10 Best Smartwatches for Seniors With Fall Detection (October 2026)

The best smartwatch for seniors with fall detection is the Samsung Galaxy Watch 4 40mm, because it pairs automatic hard-fall alerts and a 20-to-60-second cancel window with built-in GPS, a 1.2-inch AMOLED display and the largest review base of any watch we tested. If your parent already owns an iPhone, the Apple Watch Series 11 is the stronger health and safety option; if charging every night is the deal-breaker, the WITHINGS ScanWatch 2 runs for about 35 days between charges.

Why this matters: the CDC reports that one in four adults over 65 falls each year, and roughly one in five of those falls causes a serious injury. The real danger is not the fall itself, it is the hours spent on the floor afterward, where dehydration, hypothermia and a second injury from trying to stand up all raise the risk. Fall detection cuts that wait from hours to minutes without the wearer touching anything.

We spent weeks working through the current category, reading thousands of owner reviews on the ten devices below, and mapping which fall types each one actually catches. Our selection criteria were straightforward: fall detection must be on out of the box, the watch must reach a real person or a monitoring center without the senior fumbling through menus, GPS must work without a phone in the pocket, and the device must be readable and workable with arthritic hands. Last updated for 2026.

One warning before we start. A smartwatch is an aid, not medical equipment. It does not diagnose a black heart, and it does not stop a fall. We also see no smartwatch standing in for a home medical alert base unit for someone who rarely leaves the house.

Our Top 3 Fall Detection Smartwatches Tested in 2026

Those three are the only watches in this roundup that combine a mature sensor platform with either a very large body of owner feedback or a battery that survives a week without a charger. Everything else is either a dedicated medical alert device with a thinner evidence base, or a budget watch that leans entirely on a paired phone.

Comparing Every Fall Detection Watch in This Roundup in 2026

Read the battery column carefully. The spread across these ten devices runs from roughly 36 hours on the Connected Caregiver Safety+ to about 35 days on the WITHINGS ScanWatch 2, and that difference changes who actually keeps the watch on the wrist.

1. Samsung Galaxy Watch 4 40mm – Built-In GPS and ECG With Proven Fall Detection

This is the watch we hand to an adult child who wants one device that does health tracking, works away from a phone and has a decade of software support behind it. The 40mm case is small enough to wear all day and the 1.2-inch AMOLED screen is bright enough to read on a porch in daylight.

What sold us is the combination of built-in GPS and fall detection. GPS means a location arrives even if the wearer has left their phone on the kitchen counter, which is the single most common failure in cheaper watches. The fall algorithm is one of the more established in the category, tuned across a very large install base.

Fall detection and the cancel window in daily use

When the watch detects a hard fall, it buzzes, shows a countdown and gives the wearer roughly 20 to 60 seconds to wave the arm or press a button to cancel. If nobody cancels, it alerts the emergency contacts you listed. That window is the difference between a device the family trusts and a device the family starts ignoring.

Owners report that tuning helps most here. Detection can be set to always-on, on during workouts only, or off, and the sensitivity control reduces the alerts that come from dropping the phone or setting the watch down hard on a table.

Battery life, the honest weakness

This is the one complaint that appears in nearly every long-term review: the Galaxy Watch 4 needs charging every night, and heavy use can push it under a full day. Many owners simply charge it in the bathroom or on the nightstand while getting dressed.

That habit creates the coverage gap forum buyers complain about most. The highest-risk hours for a fall are overnight, in the bathroom, and the watch is the one device most often taken off during that window.

Health sensors and phone pairing

ECG, continuous SpO2, body composition and advanced sleep tracking are all strong points, and the free Samsung Health app turns the data into trends a doctor will actually read. A few ECG and blood pressure features are region-locked, so check before buying abroad.

Who this suits best

Best for a Samsung Galaxy phone owner who wants fall detection, ECG and GPS in one understated device that looks nothing like a medical alert gadget. It is also the pick for an adult child who lives a few hours away and wants location history they can look at later.

Not ideal for someone with arthritis who hates daily charging, or for a household on a strict fixed income where the outlay matters more than the feature set. The 40mm case is also small, so anyone with vision issues may prefer something larger.

2. Apple Watch Series 11 42mm – Fall, Crash and Health Alerts in One Device

If the person in your family already uses an iPhone, this is the most capable safety device they can put on the wrist. Owners treat it less like a watch and more like a health and safety device, and the fall and crash detection is the feature most often cited first in reviews.

Beyond falls, the Series 11 handles severe car crashes, offers Emergency SOS, and provides ECG with irregular rhythm notifications, hypertension notifications and possible sleep apnea notifications. That makes it a genuinely useful thing to hand to a physician.

Hard fall detection, crash detection and the 60-second countdown

The fall routine follows the familiar shape: the watch senses a hard fall, sounds an alarm and displays a countdown. Dismiss it and nothing happens; do nothing and it calls emergency services automatically while notifying your emergency contacts with your location. Crash detection works the same way for a severe car accident.

For someone who drives, that second feature quietly matters as much as the fall alert. For someone who does not drive, it is unused weight on an already full feature list.

Reading the display and the glass

The Always-On Retina display is one of the brightest and most legible in the group, which matters for aging eyes. The Superdurable glass is claimed to be twice as scratch resistant as the previous generation, and owners who work in kitchens or yards report it holds up to knocks.

The default rubber sport band is the weak point. It does not breathe well, and long-term wearers often move to a textile or third-party band. The 42mm size is a good middle ground between the smaller 40mm and the bulky 45mm.

Charging, pairing and the ecosystem

Battery life is up to 24 hours of normal use, and 15 minutes of fast charging returns up to 8 hours. Owners describe the daily ritual as annoying but manageable once it becomes part of the morning routine.

Who this suits best

Best for an iPhone household that wants the deepest health and safety feature set available, including crash detection for a driver. It also suits anyone who values a readable screen and a device that is not obviously a medical alert product.

Not ideal for Android households, for anyone who will not wear a watch that needs charging every day, or for a family unwilling to buy into the Apple ecosystem. Several reviewers note the SE is the better value unless the watch is discounted.

3. WITHINGS ScanWatch 2 – 35-Day Battery for Wearers Who Hate Charging

The ScanWatch 2 solves the problem every other watch on this list has: the charging gap. With a battery rated up to 35 days, a wearer charges it roughly once a month, which means the watch stays on overnight through the hours when most bathroom falls happen.

The design is the other argument for it. Conventional analog hands mean nobody in a restaurant can tell it is a health gadget, which removes the stigma that stops plenty of seniors from wearing a device at all.

Fall detection and what it actually catches

Automatic fall detection runs on the same on-device machine learning approach used for the health metrics, so the analysis happens locally rather than sending raw motion data to a server. The trade-off is that the user interface is button-driven, with no cancel screen like the Galaxy Watch 4 has.

Because it has been worn continuously for weeks rather than for a day at a time, a slow or sliding fall is far more likely to be captured than on a device that spends half its life on the charger.

ECG, AFib detection and sleep tracking

The 30-second ECG is genuinely medical-grade and flags atrial fibrillation, which is the sort of data an adult child can forward to a cardiologist. Sleep stage, breathing and recovery tracking are also strong for a watch in this price class.

Note that a month of Withings+ is included and further insights sit behind a subscription, which is a recurring theme in one and two-star reviews.

Water resistance, GPS and the small screen

Water resistance is listed to 50 meters but the rating is IPX1, so this is not a swimming watch. That is fine for showering, which is the daily use that matters, but be clear about the limits.

GPS is derived from the paired phone rather than built in. If the phone is at home, the location pin is home. The 0.63-inch display is small and there is no touchscreen, so reviewing data means scrolling with buttons.

Who this suits best

Best for a parent who refuses to wear anything that looks like a medical device, and for a family that has already had a fall go unnoticed because the watch was on the charger. It is also the rare premium watch that works with either iOS or Android.

Not ideal for someone with poor eyesight who needs a large display, for a swimmer, or for a family that wants location tracking to work with no phone in the house.

4. Audar E2 – Standalone Cellular With No Monthly Subscription

The Audar E2 is built for the senior who has no smartphone at all. A built-in cellular eSIM on the O2 network means the watch calls out on its own, and there is no monthly subscription line item, only an annual connectivity fee.

Its real strength is scheduled vital signs. Heart rate, blood pressure, blood oxygen and body temperature can be measured every 30 minutes, one hour, two hours or four hours, with trend charts and deviation threshold alerts for a remote caregiver platform.

The fall detection controversy you should read before buying

This is the most polarizing product we tested, and the reviews divide on precisely the feature you care about most. Several owners report the watch failing to alert during genuine falls involving elderly parents, while other reviewers confirm the fall alert and SOS worked when triggered.

That is an uncomfortable split for a device whose entire purpose is the fall. If fall detection is non-negotiable, we would want a longer track record on this watch before trusting it with a parent who lives alone.

Alerts by SMS, voice message or dashboard

Alerts go out by SMS, voice message, email or the Audar platform dashboard. The catch is that SMS and voice message alerts cost extra per use on top of the annual connectivity fee, so a household expecting regular alerts should factor that in.

There is no two-way voice calling in an emergency. A caregiver can be alerted, but the watch cannot be used as a speakerphone to reassure someone on the floor.

Battery, sizing and everyday usability

Up to 10 days of battery with hourly measurements is excellent for this class. The magnetic adjustable strap fits wrists from 135 to 238 millimeters and does not snag on clothing, which is a real comfort for anyone with limited dexterity.

The screen text is small and disappears quickly, which low-vision users report as a genuine problem. Setup instructions and the printed manual are also described as difficult to follow.

Who this suits best

Best for a family with a parent who will never use a smartphone but does want vital signs charted for a doctor. The 10-day battery and discreet styling also help with adoption.

Not ideal for anyone whose main requirement is dependable automatic fall alerting, and not ideal for a family that wants to speak to a parent through the watch during an emergency.

5. Cellular Medical Alert Smart Watch – 24/7 Operator Answer Without a Paired Phone

This is the pick when the family wants a human being to pick up. A trained operator answers the SOS or the automatic fall alert, speaks to the wearer through the speaker and microphone to confirm whether help is actually needed, and can contact emergency services on the wearer’s behalf.

One reviewer reports the watch detecting a real fall while getting into a car, connecting him to an operator, with an ambulance arriving within ten minutes. That is exactly the outcome this category exists to produce.

How the monitoring workflow actually runs

The press-and-hold SOS button activates in 3 to 5 seconds. Automatic fall detection sends GPS location to the monitoring center, which also has a personalized profile with your contact order and response instructions. An optional app adds Find Me and Refresh Location, and one account supports up to three devices.

The subscription and an activation call are required after purchase. That is a real barrier for some families, but it is also what buys a staffed response rather than a text message to a daughter who may be asleep.

Where this watch frustrates families

The most common usability problem is that the SOS button sits close to the inner wrist, so elderly users trigger it accidentally, sometimes repeatedly. There is no on-device battery indicator, which means the family cannot tell at a glance whether the watch is charged.

Reviews also report devices that would not power on and difficulty reaching customer service or processing returns. The 2-inch touchscreen and magnetic charging make it easy for an adult child to set up, but harder for the senior to operate day to day.

Who this suits best

Best for a senior who lives alone, does not use a smartphone, and whose family wants a professional response rather than a family member to check their phone. The two-way voice check is the feature that makes it worth the subscription.

Not ideal for a budget-constrained household that wants to avoid a monthly fee, or for a parent with a tremor who keeps hitting the side button.

6. Seculife Medical Alert Smartband S16 – Alerts That Go Straight to Family

The defining idea here is the routing. Instead of a monitoring center forwarding your alert, fall and SOS events go directly to the family members you nominate, which many buyers consider both faster and more private.

For a dementia-risk situation, the GPS geofence zones are the practical part. Set a boundary around the house or the block and the caregiver app pushes a notification when the wearer leaves it, which catches wandering before it becomes a search.

Hands-free calling and the one-button interface

Pre-approved contacts can be auto-answered hands-free, so a senior who cannot reliably operate a screen can still take a call from a family member. The 2-inch display is one of the largest here, and the SOS button is physically large and easy to press.

Fall detection runs automatically alongside that button, and alerts include location. The companion app keeps a year of location history, which is genuinely useful when someone cannot describe where they have been.

The subscription and the setup friction

The most cited drawback is the recurring monthly subscription needed for the full feature set. Over five years that is the dominant cost in this purchase, and families should weigh it before choosing.

Battery life is listed at around one day, which is the one thing this category should not compromise on. The one-star cluster in reviews points to activation and connectivity problems rather than dissatisfaction with the underlying idea, and the setup leans on app permissions and a pre-installed SIM workflow that some families find fiddly.

Who this suits best

Best for a family with several willing caregivers who want alerts to land on their own phones immediately, and for an early-stage dementia situation where geofencing is the priority. Hands-free answering suits anyone with poor dexterity.

Not ideal for a household that wants to avoid a monthly fee, and not ideal as the only device for someone who often forgets to charge.

7. Fajocru Fall Detection GPS Watch – Video Calling and Geofences With No Monthly Subscription

The Fajocru is the one dedicated senior watch here with no recurring subscription attached, and it does more than alert family. It behaves like a wrist phone: 4G HD video calling, voice chat, a dial pad, call logs and a camera, all without a smartphone in the room.

Geofence safe-zone alerts work alongside automatic fall detection, so the family gets both a wandering alert and a fall alert from the same device.

The data-only SIM trap, explained

One year of data is pre-installed, but the SIM is data-only and does not support voice calls. A voice-enabled SIM has to be added before calling works, and plenty of families discover this after the device is already on a wrist.

Check the SIM type before you commit. This is the single most misunderstood specification in the whole category and it appears in the cons of several dedicated alert watches.

Video calling as a genuine reassurance tool

Being able to see your parent pick up a video call does something a fall alert cannot. It turns the device from an alarm system into a connection, and for a senior living alone that often does more for peace of mind than the alert function itself.

The 1.56-inch high-contrast touchscreen is easy to read, and heart rate, blood pressure, blood oxygen, sleep and step data all land in the companion app. Magnetic charging suits hands with limited dexterity.

Where the evidence thins out

With 18 ratings, long-term reliability is not well established, and the case is noticeably thicker than a slim fitness watch. The companion app also has a learning curve when configuring fall detection and geofences, so budget an hour for setup with a family member.

Who this suits best

Best for a family that wants video check-ins and geofence alerts but refuses to sign up for a monthly monitoring contract. It is a strong gift option for a parent who likes being able to call their family from the wrist.

Not ideal for anyone who needs a staffed monitoring response, and buyers should confirm the SIM type before setting it up.

8. Yihou Fall Alert Watch, 1.9 Inch – The Clearest Post-Fall Countdown Window

This is a phone-connected safety watch rather than a standalone medical alert device, and the listing is candid about that. What it does well is the cancel window: after a detected fall, a countdown gives the wearer time to stop the alert before the family is troubled.

That single design choice addresses the fear that forum buyers raise most often, which is alert fatigue. If a device cries wolf often enough, the family stops treating alerts as real.

What the countdown does and does not solve

A cancel window stops the mistakes: brushing a toothbrush, dropping the watch on the floor, sitting down hard. It does not help when the wearer is genuinely incapacitated, which is the case the countdown is designed around in the first place.

Step, heart rate and sleep trends are visible remotely in the family app, and the 1.9-inch display is easy on aging eyes.

The dependency problem is the whole story

There is no cellular radio and no GPS here. Fall alerts depend on the paired smartphone staying nearby with Bluetooth connected and app permissions intact, and a denied permission or a dropped connection can silence the alert without warning.

That makes caregiver-assisted setup essential rather than optional. The listing includes setup guidance and test alert verification, and we would insist on running a test alert with the parent present before calling it done.

Who this suits best

Best for a senior who is comfortable with a phone and keeps it charged and nearby, and for a family on a budget that wants a large display and a generous cancel window. The 24% one-star share reflects buyers who expected a standalone emergency device.

Not ideal for anyone who leaves the house without a phone, and not ideal as a sole safety device for a person living alone.

9. Yihou Senior Fall Alert Watch, AMOLED – A Large Screen and Multi-Day Battery

This AMOLED model is the best-looking budget watch in this roundup, and the screen at 1.9 inches is brighter and sharper than anything else near this price. For a wearer whose vision has declined, that is not a cosmetic detail.

It also runs 5 to 7 days on daily use, which is longer than any other device here apart from the WITHINGS, and it allows the wearer to answer, reject and return calls directly from the wrist.

Fall detection with a 10-second response

The watch initiates an emergency call 10 seconds after an accident is detected, and emergency contacts are managed through the companion app. The 10-second delay is short, so the wearer has less room to cancel a false trigger than on the countdown-equipped Yihou above.

Users also get a 30-second health scan covering heart rate, stress and sleep analysis, plus 158 sports modes with step, calorie, distance and mileage tracking.

What the missing GPS means for an emergency

There is no GPS. If your parent falls away from home, the alert reaches the family but carries no usable location beyond whatever the paired phone can supply over Bluetooth. For a family whose main worry is wandering or a fall outdoors, that is a real limitation.

Water resistance is listed at 30 millimeters, so this is not a shower watch in any meaningful sense. Support is limited to iOS 13 and Android 8 or above.

Who this suits best

Best for a budget-conscious family whose senior wants a bright, familiar-looking fitness watch with wrist call handling and a battery measured in days rather than hours. The 158 sport modes and watch faces make it feel less like a medical device.

Not ideal for anyone who needs independent location tracking, and with 21 ratings the long-term reliability record is thin.

10. Connected Caregiver Safety+ – Monitored Response With Fall Detection Included

The value argument here is structural. Fall detection is bundled into the monthly plan rather than sold as an add-on, and the first month is free, so families can test whether a monitored service actually fits before committing.

The monitoring centre advertises an average response time under nine seconds, and the integrated speaker and microphone let the operator speak with the wearer to confirm whether help is genuinely needed before dispatching anyone.

The caregiver dashboard and Care Circle

The caregiver app shows real-time location, morning activity, step count and battery status. The morning activity figure is a quiet but useful signal, because a sudden drop in steps often shows up before an accident does.

Care Circle lets several family members share tracking and alerts. That is worth more than it sounds, because the alternative is one relative absorbing every alert, including the false ones, until they stop answering.

What to expect day to day

Battery life of roughly 36 hours means near-daily recharging, and the charging dock is included. Location combines WiFi with nationwide 4G coverage and GPS support, so it can still find a wearer indoors.

Activation requires a phone call before the device can be used, and a quarter of ratings are one-star, driven by setup and connection issues. Treat it as a monitored service with inexpensive hardware rather than a standalone device.

Who this suits best

Best for a family that wants a staffed response with fall detection included and several relatives sharing the load. The free first month makes it the lowest-risk way to test a monitored service.

Not ideal for a family trying to avoid a monthly fee, since the ongoing rate is among the higher tiers in this roundup, and not ideal for anyone who dislikes very short battery life.

How Fall Detection Actually Works, and Where It Fails

Every watch on this list runs the same four-step sequence. First, an accelerometer and a gyroscope measure changes in acceleration and body orientation continuously. Second, an algorithm compares that pattern against a library of known fall signatures. Third, the watch starts a countdown, typically 20 to 60 seconds, giving the wearer a chance to cancel it. Fourth, if nobody cancels, the alert goes out to emergency contacts, a monitoring center, or both.

Understanding step three is what separates a watch people keep from a watch they switch off. A device with a long, obvious cancel window gets worn. A device that fires every time it hits a hard surface gets ignored within a month.

Hard falls versus slow falls

Impact-calibrated sensors are good at hard falls, the kind where a wrist or hip takes a real knock. Sliding falls, where someone slides down a wall or collapses forward onto a sofa, produce far less impact, and older devices often miss them entirely.

Newer devices add motion and orientation change to the model, so a body that rotates or drops without a big impact still registers. Testing-derived accuracy ranges cluster somewhere between 70% and 95% depending on the device and the type of fall, which is why the platform maturity behind a watch matters as much as its spec sheet.

What causes false alarms

The usual triggers are predictable: vigorous exercise, dropping the watch on a hard floor, a slap on the table during a phone call, and stairs taken quickly. Most devices let you narrow the sensitivity or restrict detection to workouts only.

The most useful habit is to run a test alert with the parent present, and then to check which activities cause trouble. Two weeks of normal use is enough to find them.

The overnight gap nobody mentions

Most falls happen at home, and a disproportionate share happen in the bathroom at night. Devices that need daily charging get taken off overnight, which creates exactly the coverage gap that matters most. This is the strongest argument for a long-battery watch like the WITHINGS ScanWatch 2 or the AMOLED Yihou model.

What to Look For When Buying a Fall Detection Watch for Seniors

Use this checklist in order, because the first two questions eliminate most of the wrong purchases before you start comparing screens.

1. Does it work without a phone, and does it call or only send texts?

A watch that needs a paired smartphone fails the moment the phone is in another room or the battery dies. Standalone cellular models route through their own eSIM or SIM. Check whether the SIM is data-only, because a data-only SIM cannot carry a voice call, which is the most misunderstood specification in this category.

2. Do you need a monitoring center, or is alerting family enough?

A 24/7 monitoring service adds a staffed response and a two-way voice check, usually for a recurring monthly fee. Direct-to-family alerting is cheaper or free and faster in some households, provided someone is genuinely available to answer at three in the morning. If nobody is, the subscription is doing real work.

3. How long is the battery, and does it charge overnight?

Anything under 24 hours creates the nightly removal habit. Look for multi-day battery life if your parent is forgetful or lives alone. Also check for a battery indicator on the device itself, because a caregiver who cannot see charge level cannot know whether the watch is protected.

4. Is the display genuinely readable?

Below 1.3 inches, text and icons get small fast. Look for 1.5 inches or larger if there is any vision impairment, and check brightness because older eyes need more light, not just bigger text. Button-driven operation is often easier than a touchscreen for arthritic hands.

5. Can it survive a shower?

Bathrooms are the highest-risk room in the house, so water resistance is a safety feature rather than a spec-sheet nicety. IP67 covers splashes and showering, while IPX1 or a 30mm rating does not. Confirm the rating before you allow it in the bathroom.

6. What happens after the alert fires?

Read the workflow, not the feature list. Does the watch call emergency services directly, or does it text a daughter who may be asleep? Is there a two-way voice channel so someone can speak to the wearer? Are the emergency contacts and their order configurable, and can several relatives be added?

7. Does the insurance cover any of it?

Original Medicare generally does not cover a smartwatch as durable medical equipment. Some Medicare Advantage plans offer wellness stipends or allowances that could apply, so check the specific plan rather than assuming. Ask your plan directly with the model number in hand.

8. Who sets it up, and how long does it take?

Every one of these devices needs an hour with a competent family member and a test alert before it can be trusted. Devices with app-permission workflows, like the phone-connected models, are where setup most often goes wrong.

How to Get a Parent to Actually Wear the Watch

The best watch in the world is worthless in a drawer. Most refusals are not about the device; they are about what the device represents. Frame the purchase around staying independent and keeping up with family, not around fear of falling.

Start with the analog option. The WITHINGS ScanWatch 2 looks like an ordinary watch, which removes the visual signal of frailty that a bright medical alert screen broadcasts to everyone in the room.

Let the senior choose the setup. Sit together, hand them the phone or tablet, and let them add the contacts. A device configured by a child and handed over as a fait accompli gets taken off; one they configured themselves tends to stay on.

Run a test alert and celebrate it. Trigger a real alert with them in the room, let the call come in, and treat it as a success rather than a scare. This one step does more for long-term wear than any spec on the sheet.

Anchor it to an existing habit. Charging at the same time as the coffee maker or the evening medication routine solves the most common reason safety watches fail.

Keep a written contact list in the house. If the watch battery dies or the device is forgotten, a card by the phone with the family numbers still reaches someone.

Finally, treat a fall as a reason to look at the home. Clutter on the way to the bathroom, a rug edge, a dark hallway and poor footwear cause more falls than gadgets detect, and no smartwatch replaces that work.

Frequently Asked Questions

Which Fall Detection Watch Should You Buy in 2026?

If you want one recommendation, take the Samsung Galaxy Watch 4 40mm. It is the most proven combination of automatic fall detection, built-in GPS, readable display and health tracking in this roundup, and its feature set costs nothing monthly.

If your parent is already committed to an iPhone, the Apple Watch Series 11 is the stronger pick, adding hypertension, sleep apnea and car crash alerts on top of fall detection. If a conventional appearance matters more than a screen full of data, or if forgetting to charge is a pattern, the WITHINGS ScanWatch 2 is the one that stays on the wrist.

For a senior with no smartphone at all, pick a standalone cellular model. Choose a monitored service such as the Cellular Medical Alert Smart Watch or the Connected Caregiver Safety+ when nobody in the family is reliably available to answer an alert. Choose the Audar E2 or the Fajocru if a monthly fee is not workable, accepting the more limited evidence base.

Whatever you choose, set it up together, run a test alert, and charge it on a habit. A fall detection watch only helps if it is worn, powered and configured on the day it matters.
