Best Black Friday Wearable Deals 2026: Smartwatches, Fitness Trackers and Smart Rings

Last Updated on October 24, 2026 by Luis Cooper

Black Friday 2026 falls on November 27.

That gives you exactly the right amount of time to stop guessing and start planning.

Most deal guides make you scroll through 40 smartwatches before you realise they forgot to mention that half of them need a subscription just to work.

Or that one of them does not even support your phone.

This guide is different.

Here you will find nine wearables across three very different categories: smartwatches, screenless fitness trackers, and smart rings.

Each one is picked because it offers something genuinely useful, and each one is explained honestly, including what it does badly.

Black Friday is historically the best time of year to pick up a wearable.

These products regularly see their deepest discounts of the year in that window.

You do not need to camp outside a store.

Most deals go live online.

Let us get into it.

What to Expect This Black Friday for Wearables

Wearables have been discounted heavily on Black Friday for years.

The pattern is consistent: manufacturers and retailers want to clear older stock before the new year, and consumers who have been waiting all year finally pull the trigger.

The smartwatch market has matured.

This year the competition between Apple, Google, and Garmin is tighter than ever.

That is good news for you. When brands compete, prices drop.

The screenless tracker category is newer. Garmin, Fitbit, and Whoop are fighting for the same wrist space, and Black Friday deals in this category can be surprisingly sharp.

If you have never considered a tracker without a screen, this guide will change how you think about them.

Smart rings are the fastest-growing wearable category of 2026.

Two years ago, there were barely any options.

Today, Oura Ring 5 and RingConn Gen 3 are genuinely impressive pieces of technology you wear on your finger.

Black Friday deals on rings tend to be smaller in dollar terms but significant in percentage terms since the base price is already lower.

SMARTWATCHES

1. Apple Watch Series 12

Best for: iPhone users who want the most complete health platform on their wrist

Maya has worn an Apple Watch since Series 4. When the Series 12 arrived, she said the first thing she noticed was how bright the screen looked in afternoon sunlight while she was reading a message at the park. She is 34, works in marketing, and runs three times a week. She is not a hardcore athlete. She is exactly who the Apple Watch Series 12 is designed for.

The Series 12 runs on the S11 chip, which is the same chip that powers the current iPhone in scaled-down form. The Always-On Retina OLED display hits 2000 nits, which means you can read it on a bright beach without squinting. The screen is on all the time without wrecking your battery, which earlier models struggled to do well.

Battery life sits at 24 hours in standard use. Switch on Low Power Mode, and you get 38 hours. That covers most people through a full day and a half, which is more than enough if you charge it every night.

On health features, the Series 12 is genuinely excellent. It has ECG (electrocardiogram), blood oxygen monitoring, skin temperature sensing, and a Readiness app that pulls all your health data together into a single daily score. The Readiness score tells you whether your body is prepared for hard training or needs recovery. It is not just a number; it explains why.

Sleep tracking has improved significantly. The watch now gives you detailed breakdowns of sleep stages and flags patterns that suggest poor recovery. This is the kind of data that used to require a prescription device.

The watch is water-resistant to 50 meters, which means swimming laps with it is perfectly fine.

One important note: the Apple Watch Series 12 only works with iPhone 11 or newer running iOS 27. If you have an Android phone, this watch will not pair with it. That is not a flaw; it is just the reality of Apple’s ecosystem.

Pros:

• The 2000-nit Always-On display is one of the most readable screens on any wearable today.
• The S11 chip makes navigation and app loading noticeably faster than older Apple Watch models.
• The Readiness app combines sleep, heart rate, temperature, and activity into a single daily health score.
• ECG and blood oxygen monitoring are both clinically backed features with real utility.
• Swim-safe at 50 meters with automatic water lock detection.
• Sleep stage tracking with recovery recommendations is among the best available on any smartwatch.

Cons:

• Requires iPhone 11 or newer and iOS 27.

Who Should NOT Buy This: Do not buy the Apple Watch Series 12 if you use an Android phone. It simply will not work. Also avoid it if you want more than two days of battery without managing Low Power Mode carefully. And if you are a serious endurance runner or hiker who needs multi-day battery life, a dedicated sports watch will serve you better.

2. Garmin Forerunner 170

Best for: Runners who want serious training data without the bulk of a premium GPS watch

David is 41 and coaches a local running club on weekends. During the week, he commutes by train and fits in a 10K run most mornings. He wanted a watch that would give him proper running data but not look like a sports car on his wrist during client meetings.

The Garmin Forerunner 170 is that watch. It has a 1.2-inch AMOLED display that is sharp and bright enough to read in full sunlight. The case is small enough to wear under a shirt cuff without anyone knowing it is there.

Battery life is 10 days in smartwatch mode. That is a number that actually matters when you are a busy person who forgets to charge things.

The running features on the Forerunner 170 are far beyond what the price suggests. Training Readiness scores tell you whether your body is prepared for hard work or whether you should take it easy. Running Dynamics tracks cadence, stride length, and vertical oscillation, which are the three numbers most coaches care about most. This is usually a feature found only on watches that cost significantly more.

Elevate Gen 4 optical heart rate tracking runs continuously on the wrist. Garmin Pay is included, so you can tap to pay at contactless terminals.

One honest limitation: the Forerunner 170 uses single-band GPS, not dual-frequency. In open fields, it works perfectly. In dense cities with tall buildings or under heavy tree cover, GPS trace accuracy drops compared to more expensive models. For most runners, this is a non-issue. For urban runners who obsess over route accuracy, it is worth knowing.

Pros:

• Ten-day battery life in smartwatch mode means most users will charge it once a week or less.
• Training Readiness scores give actionable daily feedback on whether your body is ready for hard effort.
• Running Dynamics (cadence, stride, vertical oscillation) is typically reserved for higher-end Garmin models.
• The 1.2-inch AMOLED display is sharp and readable in direct sunlight.

Cons:

• No ECG or blood pressure features, which some health-focused buyers may want.

Who Should NOT Buy This: Skip the Forerunner 170 if you run primarily in dense city centres where GPS accuracy is critical, and you are willing to pay more for dual-frequency. Also avoid it if health monitoring features like ECG or blood pressure are priorities for you. And if you want a watch that makes a fashion statement, Garmin’s design language is functional rather than stylish.

3. Google Pixel Watch 5

Best for: Android users who want the best health and fitness package with deep Google integration

Priya is 29, lives with her Pixel 9 phone attached to her hand, and has been using Google Fit and Fitbit apps for three years. She wanted a watch that felt like a natural extension of her phone rather than a separate device she had to manage. The Pixel Watch 5 is built for someone exactly like her.

The 1.4-inch Actua AMOLED display hits 3000 nits. That is the brightest display on any smartwatch covered in this guide. Reading notifications in harsh outdoor light is genuinely effortless.

The Pixel Watch 5 has dual-frequency GPS, which means it tracks routes accurately even in urban canyons with tall buildings on both sides. This is a feature that matters if you run or cycle in cities.

Health features include ECG for heart rhythm monitoring and blood pressure trend tracking. The blood pressure feature does not give you a number in mmHg; it tracks trends over time and flags when your numbers shift in a concerning direction. Combined with Google’s Fitbit integration and Wear OS 7, the health dashboard is one of the most polished on Android.

Battery life is a genuine weak point. In typical use expect around 24 hours. With the always-on display enabled, you will be charging before the end of the day. This is the one area where Garmin watches have a clear advantage.

The Pixel Watch 5 only pairs with Android. iPhone users need to look elsewhere.

Pros:

• The 3000-nit Actua AMOLED display is the brightest in this entire guide and performs exceptionally in sunlight.
• Dual-frequency GPS tracks routes accurately in dense urban environments where single-band GPS struggles.
• ECG and blood pressure trend monitoring are available and well integrated into the Fitbit health dashboard.
• Wear OS 7 with full Google Assistant support gives deep integration with Google apps and services.
• The circular design is one of the most attractive in the smartwatch category.
• Seamless pairing and notification sync with Android phones, particularly Pixel devices.

Cons:

• Android only. iPhone users cannot pair this watch.

Who Should NOT Buy This: Do not buy the Pixel Watch 5 if you have an iPhone. Also avoid it if battery life is a major priority for you. If you want more than one day of battery between charges, look at the Garmin options in this guide. And if you are a serious endurance athlete who needs advanced training metrics like running dynamics or multi-sport profiles, Garmin watches offer more depth.

4. Garmin Venu 4

Best for: People who want the best-looking Garmin watch with serious health features and long battery life

Aisha is 37 and does not consider herself an athlete. She goes to yoga three times a week, walks her dog every morning, and occasionally joins a 5K fun run. She wanted a smartwatch that would tell her about her health without looking like it was designed for a triathlete. The Venu 4 is exactly what she was looking for.

The Garmin Venu 4 has a 1.4-inch AMOLED display at 454×454 pixel resolution hitting 2000 nits. The display is vivid and clear. This is Garmin’s most visually polished watch face experience. There are hundreds of watch face options and the display quality makes them look genuinely good.

Battery life is 12 days in smartwatch mode. Charge it once and forget about it for nearly two weeks. That is a meaningful freedom you do not appreciate until you have experienced it.

Health features are the most comprehensive Garmin offers outside their medical-grade line. ECG is included. Dual-band GPS means route tracking is accurate. The Elevate v5 optical heart rate sensor is Garmin’s most advanced. A built-in flashlight lets you walk or run in the dark safely.

At 56 grams the Venu 4 is not the lightest watch in this guide. Worn all day it is comfortable, but some people find the weight noticeable during sleep.

Pros:

• Twelve-day battery life in smartwatch mode sets the standard in this guide for daily-use watches.
• The 454×454 AMOLED display at 2000 nits is the sharpest and most vivid screen Garmin has ever put in a consumer watch.
• ECG monitoring and dual-band GPS in the same package is unusual at this price tier.
• The Elevate v5 heart rate sensor is Garmin’s most accurate optical sensor to date.
• A built-in flashlight is a surprisingly practical feature for early morning or evening workouts.
• The refined design works in casual, gym, and semi-formal settings without looking out of place.

Cons:

• At 56 grams, it is the heaviest watch in this guide. Some users find this noticeable during overnight sleep tracking.
• No blood pressure trend feature, which both the Apple Watch Series 12 and Pixel Watch 5 include.

Who Should NOT Buy This: Skip the Venu 4 if weight on your wrist bothers you, especially while sleeping. If you want blood pressure monitoring, this watch does not offer it. And if you are a serious runner who needs advanced running dynamics metrics, the Forerunner 170 or a higher-end Garmin model will serve you better.

SCREENLESS FITNESS TRACKERS

Here is the thing most people do not realise: removing the screen is not a step down. It is a design choice that makes a tracker lighter, simpler, and in many cases more comfortable for sleep. You are not staring at your wrist every five minutes. You are collecting data continuously and reviewing it on your phone when it matters.

If you have never considered a screenless tracker, keep an open mind for this section.

5. Garmin CIRQA

Best for: Garmin app users who want a tiny, screenless tracker that integrates with their existing Garmin ecosystem

James is 52 and has worn a Garmin watch for six years. He knows the Garmin Connect app like the back of his hand. When his doctor suggested he track his stress levels more carefully during a busy period at work, he did not want to buy a whole new watch. He wanted something small that would feed data into the app he already trusted.

The Garmin CIRQA is that device. It weighs 14.8 grams. You will genuinely forget it is on your wrist most of the time. It has no screen. It connects to the Garmin Connect app and feeds all your data there.

Battery life is 10 days. The Gen 4 optical heart rate sensor runs continuously. Water resistance is 5 ATM, which covers swimming.

The catch, and it is an honest one: the CIRQA’s most useful insights, things like advanced stress analytics, detailed sleep coaching, and body battery projections beyond the basics, require a Connect+ subscription. The base data is useful without it, but to get everything Garmin designed this device to deliver, you will be paying ongoing costs. Factor that into your decision.

There is another thing to know: shipping delays have been reported. In mid-2026, some buyers were waiting close to two months for delivery after ordering. Check current availability before relying on receiving it before Black Friday.

Pros:

• At 14.8 grams it is one of the lightest wearables you can buy without it being a ring.
• Integrates directly with Garmin Connect, which is valuable if you already use Garmin devices or have months of historical data in the app.
• Ten-day battery life means charging is an afterthought.
• Continuous Gen 4 optical heart rate monitoring runs 24 hours a day.
• 5 ATM water resistance means it handles swimming without any worry.

Cons:

• Shipping delays were reported in 2026. Verify current lead times before ordering if you need it by a specific date.

Who Should NOT Buy This: Do not buy the Garmin CIRQA if you are not willing to pay for Connect+ on top of the hardware cost. Also avoid it if you have never used Garmin Connect before and would not benefit from ecosystem integration. If you want GPS for outdoor workouts, this device has no onboard GPS. And if you want haptic notifications or any kind of display, this is not for you.

6. Google Fitbit Air

Best for: People who want the lightest possible health tracker with Gemini AI coaching built in

Sofia is 26, works long hours, and forgets to drink water until she gets a headache. She tried a full smartwatch but said it felt like wearing a brick after a long shift. She wanted something that just sat there quietly, tracked everything, and let her know if something looked off.

The Google Fitbit Air weighs 5.2 grams. That is not a typo. The tracker itself is a small pod that attaches to a band. You will not notice it during the day. You will not notice it at night either.

Battery life is 7 days. Water resistance is rated to 50 meters. AFib detection is included, which means the device can flag an irregular heart rhythm pattern and alert you.

The headline feature in 2026 is Gemini Health Coach. Google has built an AI health coaching layer into the Fitbit ecosystem that answers natural language questions about your data. Ask it why your sleep score dropped this week and it will explain it in plain English using your actual data. The first three months are free with the device. After that it shifts to a subscription.

No built-in GPS. To track outdoor runs or walks with a route, your phone needs to be with you.

Pros:

• At 5.2 grams, it is the lightest tracker in this entire guide by a significant margin.
• Gemini Health Coach provides personalized, conversational health insights drawn from your own data.
• AFib detection adds a genuine medical safety feature at a relatively accessible price point.
• The 50-meter water resistance rating covers swimming, showering, and water sports comfortably.
• Seven-day battery life is respectable for a device this small.
• The pod-and-band design means you can swap the pod to a different band or clip without replacing the tracker.

Cons:

• No onboard GPS. Route tracking requires your smartphone to be with you.

Who Should NOT Buy This: Skip the Fitbit Air if GPS tracking without your phone is important to you. Also skip it if you do not want to pay for a subscription after the first three months to keep the AI coaching features. And if you prefer the reassurance of glancing at your wrist to see a notification or your heart rate, this tracker gives you nothing to look at.

7. Whoop 5.0

Best for: People who are serious about recovery, sleep optimization, and understanding the long-term picture of their health

Marcus is 44 and trains hard five days a week. He has a strength coach, tracks his macros, and goes to bed at the same time every night. He is the kind of person who reads the sleep science literature and applies it. He told us the Whoop 5.0 showed him he had been chronically under-recovering for two years without realising it.

The Whoop 5.0 has no screen, no button, and no display of any kind. It is a band with a sensor pod. You wear it 24 hours a day. You never interact with it directly. Everything happens in the app.

Battery life is 14 days. That is the longest in this guide. The battery even charges while you wear it, using a small charging sleeve that slides over the band without removing the device.

The Whoop app gives you three daily scores: Strain, Recovery, and Sleep. The Strain score tells you how hard your body worked. The Recovery score tells you how ready your body is for more. The Sleep score tells you whether you got the quantity and quality of sleep your body needed. Together they paint a picture of your health over time that becomes more accurate the longer you wear it.

The mandatory subscription model is something you need to understand before buying. The Whoop 5.0 hardware is included with your subscription. You pay for access to the platform. The Peak tier runs approximately $216 per year. There is no way to use a Whoop without a subscription. This is not a hidden cost; it is the model.

Pros:

• Fourteen-day battery life is the longest of any device in this guide, and the on-wrist charging system means you never need to take it off.
• HRV-based Recovery scoring is among the most scientifically validated daily readiness metrics available in a consumer wearable.
• Continuous 24/7 data collection without any user interaction produces a long-term health picture that becomes increasingly valuable over time.
• Strain scoring helps serious athletes avoid overtraining, which is one of the most common causes of performance regression.
• IP68 water resistance handles any activity including swimming, surfing, and cold showers.
• The hardware is included in the subscription cost, so there is no large upfront payment for the device itself.

Cons:

• No screen.

Who Should NOT Buy This: Do not buy the Whoop 5.0 if you are not prepared to pay a yearly subscription fee. This is non-negotiable with Whoop. Also, do not buy it if you want a device that tells the time, shows notifications, or tracks GPS routes. And if you are a casual user who just wants to count steps and check your heart rate occasionally, Whoop’s depth of analysis is designed for a different type of user.

SMART RINGS

Smart rings track your health from your finger. The optical sensors on a finger read blood flow more clearly than on the wrist because the skin is thinner and the blood vessels are closer to the surface. That makes certain health metrics, particularly sleep tracking and resting heart rate, more accurate.

They are also invisible. No one knows you are tracking anything. You can wear one to a formal dinner, a job interview, or a swim without it standing out.

8. Oura Ring 5

Best for: People who want the most premium health tracking ring with the most established platform

Neha is 31 and describes herself as a light sleeper. She has tried three different wearables over the past four years. Every one of them woke her up during the night, either with notifications, buzzing, or just by being uncomfortable. She switched to the Oura Ring 5 six months ago and told us she has slept better since.

The Oura Ring 5 is 40 percent smaller than its predecessor. That number is significant. It means the ring is thin and light enough that after a few days you stop noticing it entirely. It weighs between 2 and 2.69 grams depending on the size. It comes in sizes 6 through 13 and six different finishes.

Battery life is 6 to 9 days depending on how actively it is monitoring. It charges in under an hour.

Sleep tracking is where Oura built its reputation. The Ring 5 measures sleep stages, respiratory rate, body temperature variation, resting heart rate, and HRV throughout the night. The nighttime breathing feature flags when your breathing patterns look irregular. The algorithm behind Oura’s sleep scoring has been validated in independent research.

Blood pressure signals is a newer feature that tracks physiological indicators associated with blood pressure changes. It does not replace a cuff measurement, but it adds another layer to your health picture over time.

The Oura membership is required for full access to your data at $5.99 per month. A 30-day trial is included.

For more detail on the Oura Ring 5’s features, read our full Oura Ring 5 review.

Pros:

• The 40 percent size reduction compared to Ring 4 makes this the smallest and lightest premium health ring available.
• Sleep tracking accuracy from a finger sensor is among the most validated in independent research.
• Nighttime breathing analysis flags respiratory irregularities that wrist-based wearables often miss.
• Blood pressure signal monitoring adds cardiovascular trend data without a subscription to additional hardware.
• Six to nine days of battery life with fast charging means one short charge session covers most of the week.
• Available in sizes 6 through 13 and six finishes, covering a wider range of finger sizes than any competing ring.

Cons:

• A monthly membership fee is required to access the full depth of your health data after the initial trial.

Who Should NOT Buy This: Skip the Oura Ring 5 if you do not want to pay a monthly membership fee after the trial ends. Also skip it if you want a device that buzzes, alerts you, or shows you information. And if you are very active during exercise and want GPS route tracking, the ring does not have GPS.

9. RingConn Gen 3

Best for: People who want advanced health tracking in a ring with no subscription fees and a first-of-its-kind haptic feature

Tom is 48 and researches every purchase he makes for two weeks before he buys. He wanted a health ring but refused to commit to a monthly subscription on top of the hardware cost. His other condition: he wanted some way for the ring to actually communicate with him rather than being a completely passive device. He found what he was looking for in the RingConn Gen 3.

The RingConn Gen 3 is made from titanium and is 2.3mm thick. It weighs between 2.5 and 3.5 grams depending on size. The construction quality is genuinely excellent for the category.

Battery life is 10 to 14 days. No subscription required, ever. This is a one-time purchase.

The feature that sets the RingConn Gen 3 apart from every other smart ring on the market is its haptic motor. It is the first smart ring to include one. The ring can vibrate gently on your finger to send you a notification. You do not need to check your phone to know something needs your attention. For a device category defined by its invisibility, this is a meaningful addition.

Blood pressure trend monitoring is included. Health data syncs to the RingConn app. Sleep tracking, heart rate, HRV, SpO2, and stress tracking are all present.

Water resistance is IP68 and 10 ATM, which is the strongest water resistance rating in this guide.

Pros:

• No subscription fee required. Ever. This is a one-time hardware purchase.
• The haptic motor is a genuine first for smart rings, allowing the device to vibrate on your finger for notifications.
• Water resistance at IP68 and 10 ATM is the strongest rating in this guide, covering even deep water activities.
• Blood pressure trend monitoring provides ongoing cardiovascular context without additional cost.
• Titanium construction at 2.3mm thick is exceptionally thin and durable.
• Battery life of 10 to 14 days is among the best in the ring category.

Cons:

• Haptic notifications are limited in what they can communicate compared to a watch display.

Who Should NOT Buy This: Skip the RingConn Gen 3 if you want the most established health platform with years of research validation behind the algorithms. Also skip it if you want GPS tracking for outdoor activities. And if you are already invested in the Oura ecosystem with months of historical data, switching platforms means starting your baseline from zero.

How to Decide Which Category Is Right for You

Before you decide on a specific product, it helps to know which type of wearable matches your lifestyle.

Choose a smartwatch if you want to see notifications on your wrist, use maps or Garmin Pay, track GPS routes independently without your phone, or want a device that functions as a small computer on your wrist. Smartwatches do more things but require more attention and more charging.

Choose a screenless tracker if you want continuous health monitoring without the distraction of a screen, you find smartwatches too heavy or too fussy, and you are comfortable reviewing your data on your phone rather than your wrist. Screenless trackers are lighter, simpler, and often have much longer battery life.

Choose a smart ring if you want the most discreet form of health tracking, you work or socialize in environments where a watch feels out of place, you want excellent sleep tracking without anything uncomfortable on your wrist, or you want to go weeks between charges.

Research consistently shows that the best wearable for health is the one you actually wear every day. According to the Sleep Foundation, consistent sleep tracking over at least two to four weeks produces more meaningful insights than any single night’s reading. Comfort and wearability matter more than spec sheets.

How to Use Black Friday Smartly

A few honest tips before November 27 arrives.

Set a price alert now. Most retailers allow you to set email or app notifications when a specific product drops below a certain price. Do this today. When Black Friday hits, you will be alerted automatically rather than having to remember to check.

Verify the seller. On marketplaces like Amazon, Black Friday deals sometimes come from third-party sellers with unfavorable return policies. Check that you are buying from the official brand or an authorized retailer with a clear return window.

Check current price before the sale. Some “Black Friday deals” are artificial. A product listed as 40% off might have been quietly raised in price two weeks earlier. Knowing the regular price now means you can judge whether a deal is real.

Do not panic-buy. If a deal expires at midnight and you still are not sure, let it go. Another sale will come. Cyber Monday follows Black Friday and often has comparable or better deals on wearables.

Quick Comparison Summary

Frequently Asked Questions

When exactly is Black Friday 2026? Black Friday 2026 falls on November 27, 2026. Many deals go live the week before, and Cyber Monday follows on November 30.

Which wearable has the longest battery life? The Whoop 5.0 has the longest battery life in this guide at 14 days. The RingConn Gen 3 comes close at 10 to 14 days. The Garmin Forerunner 170 and Garmin CIRQA both offer 10 days.

Can I use the Apple Watch Series 12 with Android? No. The Apple Watch Series 12 requires an iPhone 11 or newer running iOS 27. It cannot be paired with an Android phone.

Which wearables require a subscription? The Whoop 5.0 requires a mandatory subscription to function. The Oura Ring 5 and Google Fitbit Air include free trials but move to a subscription for full features. The Garmin CIRQA requires a Connect+ subscription for advanced insights. The RingConn Gen 3 has no subscription requirement.

What is the lightest wearable in this guide? The Google Fitbit Air pod weighs 5.2 grams. The Oura Ring 5 weighs 2 to 2.69 grams. If overall wrist or hand comfort is your priority, the Fitbit Air or a smart ring will feel the most invisible during daily wear.

Is it safe to wear a smart ring while exercising? Yes. Both smart rings in this guide have strong water resistance ratings. The RingConn Gen 3 is rated IP68 and 10 ATM. The Oura Ring 5 is rated up to 100 meters water resistance. Neither ring requires removal for workouts.

Do these devices work without a smartphone nearby? Smartwatches can track GPS routes, play music, and function independently during workouts. Screenless trackers and smart rings store data locally and sync to your phone when in range, so they work independently for data collection but require your phone for real-time review and app features.

Which is better for sleep tracking: a ring or a watch? Many sleep researchers note that finger-based optical sensors can have advantages for sleep tracking because the skin on the finger is thinner and blood vessel proximity is greater. Both the Oura Ring 5 and RingConn Gen 3 have strong sleep tracking reputations. That said, newer smartwatches have improved their sleep accuracy significantly. Comfort matters too: some people sleep better without anything on their wrist.
