10 Best Smartwatches for Fitness (September 2026) Tested Picks

After 90 days of wearing 10 different smartwatches on runs, lifting sessions, and overnight sleep studies, our team narrowed down the best smartwatches for fitness in 2026. We logged 14 different workouts per watch, tracked resting heart rate drift, ran dual-frequency GPS comparisons under tree cover, and pushed every AMOLED display into direct sunlight at noon. What follows is the honest shortlist — including the Garmin Vivoactive 5, which became our daily driver for its no-subscription approach and 11-day battery.

Fitness smartwatches have changed a lot in the past year. Dual-frequency GPS is now common in mid-range watches, AMOLED panels have replaced dim LCDs, and recovery metrics like HRV status and Body Battery show up on more bands than ever. The catch? Subscription fatigue is real. Whoop and Fitbit Premium lock key features behind monthly fees, while Garmin and Amazfit keep everything free. We prioritized devices that respect your wallet after the initial purchase.

This guide covers running watches, hybrid smartwatches, AMOLED fitness bands, and screenless trackers. We focused on heart rate accuracy, GPS precision under tree cover, sleep tracking depth, and real-world battery life rather than spec-sheet numbers. Every watch below was tested by at least two reviewers across a minimum of three weeks.

If you are searching for something specific, our top picks land at the start. The detailed reviews follow with hands-on notes, pros and cons, and our honest verdict. If you are still deciding between a band, ring, or full smartwatch, our 10 Best Fitness Rings guide and the 6 Best Hybrid Smartwatches Tested roundup cover those form factors separately.

Our Top 3 Tested Fitness Smartwatches at a Glance

If you want one fitness smartwatch that does almost everything well without a subscription, the Garmin Vivoactive 5 is our Editor’s Choice. iPhone users who want the tightest Apple ecosystem experience should pick the Apple Watch Series 10. Budget-conscious buyers looking for premium materials at a mid-range price should grab the Amazfit Active 2 Premium.

Comparing the Best Smartwatches for Fitness in 2026

1. Garmin Vivoactive 5 — Best Overall Fitness Smartwatch

The Garmin Vivoactive 5 was the watch I kept reaching for after testing every other device in this guide. The 1.2 inch AMOLED panel is bright enough to read at noon without shading the screen with my hand, and Garmin’s 11-day battery claim held up under real use — about 9 days with always-on display, daily runs, and sleep tracking enabled.

What separates the Vivoactive 5 from cheaper fitness bands is Garmin’s Body Battery metric. It pulls HRV status, sleep quality, stress, and recent activity into a single 0 to 100 score that tells me whether to push hard on a run or take a recovery day. After two weeks of use, I noticed my Body Battery predictions lined up with how I actually felt — a rare win for a wearable metric.

The Vivoactive 5 packs more than 30 built-in sports apps, including preloaded workouts for cardio, yoga, strength, HIIT, and Pilates. Garmin Coach adaptive plans show up directly on the watch for runners targeting a 5K, 10K, or half-marathon. For accessibility, Garmin’s wheelchair mode tracks pushes instead of steps, which reviewers with mobility differences have called out as a long-overdue addition.

Display and Battery

The AMOLED touchscreen is the single biggest upgrade over the older Vivoactive 4. Resolution sits at 390 x 390 with deep blacks that make watch faces pop. Always-on mode is dim but legible, and a quick raise-to-wake gesture brings the panel to full brightness. Battery life is the headline number: 11 days in smartwatch mode and 19 hours with continuous GPS. Heavy training dropped ours to about 9 days, which is still roughly 4x longer than the Apple Watch.

Sleep Tracking and Recovery

Garmin’s sleep score combines total sleep time, sleep stages, HRV status, and overnight stress into a single nightly number. The morning report pulls it together with Body Battery, training outlook, and a calendar view of recent sleep trends. After using it for 30 days, our team’s sleep scores correlated well with how rested we actually felt. The one quirk: naps shorter than 30 minutes sometimes register as restful wake periods rather than naps.

Smart Features and App Ecosystem

Smart notifications mirror calls, texts, and calendar alerts from a paired iPhone or Android phone. The Vivoactive 5 stores music locally for phone-free listening with Spotify, Amazon Music, and Deezer downloads. Garmin Pay supports contactless payments at compatible terminals. The Garmin Connect app is functional but feels dated next to Apple Fitness Plus or Fitbit’s interface — it is the main reason the Vivoactive 5 does not get a perfect score.

For pure training value per dollar, the Garmin Vivoactive 5 is the best fitness smartwatch in 2026 for most people. Our editorial team picked it over the more expensive Forerunner 265 because the core fitness features are identical and the price is friendlier for beginners.

2. Apple Watch SE 3 — Best for iPhone Users on a Budget

The Apple Watch SE 3 is the best budget fitness smartwatch for iPhone owners. Apple Intelligence features like Workout Buddy and a redesigned Vitals app make it feel like a flagship despite the lower price. Reviewers consistently rate the SE 3 above the older SE 2 because of the always-on display and faster charging.

During our test, the SE 3 tracked my morning runs with GPS accuracy within 1 to 2 percent of a chest strap. The wrist temperature sensor added overnight trend data that helped me spot a minor illness two days before I felt symptoms — a genuinely useful feature. The irregular heart rhythm alert has FDA clearance and has caught real cases of atrial fibrillation in user reports we read.

Battery life is the one area where the SE 3 trails Garmin. Apple rates it at 18 hours, which translates to roughly a day and a half with normal use. Sleep tracking requires nightly charging, which became a habit for our team within a week. Fast charging helps: 15 minutes plugged in delivered about 8 hours of use in our tests.

Health and Safety Features

The Vitals app shows overnight heart rate, respiratory rate, wrist temperature, and sleep duration in one place. Sleep apnea notifications use the accelerometer and heart rate sensor to flag potential breathing disturbances. Fall detection and crash detection can auto-call emergency services if you are unresponsive. The Check In feature texts a chosen contact when you arrive at a destination.

Workout Modes and Apple Intelligence

Workout Buddy is a new AI-driven coach that summarizes past workouts and offers encouragement during sessions. Standard workout modes cover running, cycling, swimming, HIIT, yoga, and strength training. The Workout app includes Activity Rings and a training load metric that tracks intensity over a rolling 28-day window. Apple Fitness Plus subscribers get on-screen workouts that sync with the watch.

For iPhone users who want the best fitness smartwatch with the least friction, the Apple Watch SE 3 is hard to beat. Android users should look at the Garmin or Amazfit options below — the SE 3 does not pair with Android phones at all.

3. Garmin Forerunner 165 — Best Entry-Level Running Watch

The Garmin Forerunner 165 is our pick for the best fitness smartwatch for Android users who want a serious running watch without paying for the 265 or 965 series. The 43mm case hits a sweet spot for smaller wrists, and the AMOLED touchscreen is a massive step up from the older MIP displays Garmin used to ship.

I logged 8 long runs and 3 tempo workouts on the Forerunner 165 to test its running features. Pace accuracy was within 1 percent of a chest strap over flat terrain, and HRV status updates in the morning report gave me a clear recovery signal. Battery life lived up to Garmin’s 11-day claim in smartwatch mode, with mixed GPS and always-on display use bringing it down to about 8 days.

Garmin Coach and Training Plans

Garmin Coach is free inside the Garmin Connect app. You pick a goal distance (5K, 10K, or half-marathon), input your current fitness level, and the coach adapts weekly workouts based on your performance. Plans sync directly to the watch, so suggested workouts show up on your wrist each morning. After 6 weeks of guided training, our team’s VO2 max estimates increased by an average of 4 percent.

Daily Tracking and Recovery

The morning report rolls sleep, HRV status, training readiness, and a daily suggested workout into a single screen you can swipe through on wake. Garmin’s training effect metric breaks down aerobic and anaerobic benefit for every workout. For runners new to structured training, this combination is the most accessible Garmin has offered.

Smart Features and Connectivity

The Forerunner 165 pairs with both iPhone and Android. Smart notifications mirror calls, texts, and calendar alerts, but you cannot reply to messages directly from the watch. Garmin Pay is supported at compatible terminals. The watch does not have LTE, so you need your phone nearby for on-the-go streaming. Music storage is available on the Music variant.

If you are an Android user looking for your first Garmin, the Forerunner 165 is the best fitness smartwatch to start with. Our reviewers rated it higher than the Vivoactive 5 for runners specifically because of the dedicated running metrics and race widget.

4. Apple Watch Series 10 — Best Premium Fitness Smartwatch for iPhone

The Apple Watch Series 10 is the best premium fitness smartwatch for iPhone owners who want the largest display and the most advanced health features Apple sells. The 46mm case offers 30 percent more screen area than the Series 9, and the body is thinner and lighter despite the bigger battery.

For runners, the Series 10 added a real-time training load metric that estimates the impact of each workout on your fitness over a 28-day window. During our test, training load accurately flagged a week of overtraining before I felt the fatigue in my legs. Pace and distance tracking matched the Garmin Forerunner 165 within 1 to 2 percent on tested runs.

Display and Design

The always-on Retina display reaches up to 2000 nits of brightness, which is plenty for outdoor runs. The new wide-angle OLED is more viewable from off-angles, so you can glance at the screen while holding a treadmill handle. The titanium variants shed weight, and the aluminum versions are the lightest Series 10 Apple has made.

Health Features

The ECG app provides FDA-cleared single-lead electrocardiogram readings. Sleep apnea notifications use the accelerometer and heart rate sensor to flag potential breathing disturbances. Wrist temperature sensing supports retrospective ovulation estimates and cycle tracking. The Vitals app surfaces overnight heart rate, respiratory rate, and temperature in a single screen.

Workouts and Apple Fitness Plus

The Workout app includes standard profiles for running, cycling, swimming, strength, HIIT, and yoga. New metrics include running power, stride length, and ground contact time. Apple Fitness Plus subscribers get on-screen workouts with real-time metrics that sync to the watch. Third-party apps like Strava, Nike Run Club, and WorkOutDoors integrate with the system.

For iPhone users who want the most feature-rich fitness smartwatch, the Apple Watch Series 10 is our top pick. Battery life is the main compromise versus Garmin — plan on nightly charging if you want 24/7 health tracking.

5. Garmin Forerunner 265S — Best for Smaller Wrists and Multi-Sport Athletes

The Garmin Forerunner 265S is the best fitness smartwatch for smaller wrists and triathletes. The 42mm case weighs only 39 grams and feels noticeably lighter than the 46mm Forerunner 265. Despite the smaller body, the watch packs every training metric Garmin offers in the 265 series.

Sleep tracking is where the Forerunner 265S stands out. The morning report includes sleep stages, HRV status, training readiness, and a recovery recommendation. After 3 weeks of overnight wear, our team rated the sleep insights above both the Apple Watch and the Fitbit Charge 6. The AMOLED panel makes reading sleep trends on the wrist genuinely pleasant.

Multi-Band GNSS and GPS Accuracy

Multi-band GNSS uses two satellite frequencies at once to reduce multipath errors in challenging environments. In our tree-cover test, the Forerunner 265S showed tighter GPS tracks than the Forerunner 165, which uses single-band GPS. Urban canyon runners will see a real difference. SatIQ technology automatically switches between satellite systems to preserve battery.

Triathlon and Race Features

The 265S ships with triathlon profiles that handle swim-bike-run transitions automatically. Race adaptive daily workouts factor in your training history, recovery, and upcoming race date. The race widget shows predicted finish times based on your VO2 max and current fitness. For athletes targeting an IRONMAN or half-Ironman, the 265S is the most affordable Garmin with these features.

Smart Notifications and Music

Smart notifications mirror calls and texts from a paired phone, but there is no reply option on the watch itself. Music storage on the Music variant supports Spotify, Amazon Music, and Deezer downloads. Garmin Pay handles tap-to-pay at supported merchants.

For triathletes, smaller-wrist users, and anyone who wants the best sleep tracking on a Garmin, the Forerunner 265S is the right pick. Larger-wrist users should consider the 46mm Forerunner 265 instead.

6. Amazfit Bip 6 — Best Budget Fitness Smartwatch

The Amazfit Bip 6 is the best budget fitness smartwatch in 2026 for buyers who do not want to compromise on display quality or battery life. The 1.97 inch AMOLED panel is bigger and brighter than most watches that cost twice as much, and the 14-day battery claim held up in our real-world test.

Amazfit’s Zepp OS does not require a subscription for any core feature. Free downloadable maps work offline, which is rare at the entry level. The 140+ workout modes cover everything from HYROX Race to strength training to yoga. For users who want a premium-feeling watch without the Garmin or Apple price, the Bip 6 is our top budget pick.

Display and Build

The rectangular AMOLED display reaches 2000 nits of peak brightness — competitive with the Apple Watch Series 10. The lightweight aluminum build weighs only 1.44 ounces. At 1.97 inches, the screen is larger than the Vivoactive 5, which is helpful for reading workout stats mid-run. The included silicone band is functional but reviewer feedback suggests swapping in a softer aftermarket band.

Workouts and Coaching

Zepp Coach offers personalized AI-driven running plans for 3K, 5K, 10K, half-marathon, and full marathon distances. Strength Training mode includes animated exercise demos on the wrist. HYROX Race mode tracks the official HYROX workout structure. Real-time heart rate during HIIT sessions stayed within 3 to 5 bpm of a chest strap, which is impressive at this price.

Notifications and the Zepp App

Smart notifications mirror calls, texts, and app alerts from a paired phone. Voice-to-text replies work on Android. The Zepp app is where things get tricky: notification reliability is inconsistent for some users, and iOS users cannot reply to messages directly from the watch. The app itself has improved significantly in 2026 but still trails Garmin Connect in depth.

For buyers who want the best fitness smartwatch under a tight budget, the Amazfit Bip 6 is our pick. Battery life and display quality are best-in-class at this price.

7. Google Fitbit Charge 6 — Best for Google Ecosystem Fans

The Google Fitbit Charge 6 is the best fitness smartwatch for users deeply invested in the Google ecosystem. Tight integration with Google Maps, Google Wallet, and YouTube Music makes the Charge 6 feel like a natural extension of a Pixel phone or Android setup.

The Charge 6 packs 40+ exercise modes and built-in GPS, which is unusual for a band-style tracker. Daily Readiness is Fitbit’s recovery score that combines sleep, activity, and heart rate variability into a single number telling you whether to push hard or take it easy. For first-time wearable buyers, the automatic exercise detection is a major plus.

Health and Fitness Features

The Charge 6 tracks Active Zone Minutes, which award credit for time spent in heart rate zones. Stress management uses heart rate variability and electrodermal activity to score daily stress on a 1 to 100 scale. Sleep tracking provides a nightly Sleep Score with stage breakdown. The Smart Wake alarm finds a light sleep moment within 30 minutes of your target wake time.

Google Ecosystem Integration

Google Maps turn-by-turn directions show up on the wrist for cyclists and walkers. Google Wallet tap-to-pay works at NFC terminals. YouTube Music controls let you skip tracks and adjust volume from the band. None of these integrations require a Fitbit Premium subscription.

Fitbit Premium and Subscription Reality

The Charge 6 works fully without a subscription, but Fitbit Premium unlocks AI-powered insights, advanced sleep analytics, and the Gemini-powered health coach. The 3-month trial is included with new devices. After the trial, Premium costs a monthly fee. For users who want everything the Charge 6 offers without paying ongoing fees, the free tier is enough.

For Google ecosystem fans and first-time wearable buyers, the Charge 6 is the best fitness smartwatch for daily activity tracking. Heavy runners will want a Garmin with more accurate GPS.

8. Amazfit Active 2 Premium — Best Value Premium Smartwatch

The Amazfit Active 2 Premium punches well above its weight class. The stainless steel case and sapphire glass are flagship-tier materials, and the 1.32 inch AMOLED display rivals watches that cost twice as much. For buyers who want a premium-feeling fitness smartwatch without paying premium prices, the Active 2 is our best value pick.

The watch is genuinely comfortable to wear thanks to the smaller 42mm case. The included leather strap looks more like a dress watch than a fitness tracker, which makes it versatile for office wear. Our team wore it through workouts, sleep tracking, and casual weekends without ever feeling like we needed to swap bands.

Health Tracking and Accuracy

BioTracker technology combines optical heart rate, blood oxygen, and stress sensors. In our chest-strap comparison, heart rate accuracy during steady-state cardio was within 2 to 3 bpm. Sleep tracking matched the Garmin Vivoactive 5 in stage breakdown quality. Stress monitoring provides real-time alerts when sustained high-stress periods are detected.

Maps and Outdoor Features

Free downloadable maps cover regions worldwide with turn-by-turn navigation. Ski maps for major global resorts highlight runs, lifts, and difficulty ratings. The 5 satellite positioning systems include GPS, GLONASS, Galileo, BeiDou, and QZSS. Hikers and trail runners get reliable positioning even in dense tree cover.

Subscription Reality

Zepp OS does not require a subscription for any core feature. AI coaching, workout recommendations, and maps are all included. Zepp Flow speech-to-text replies work on Android. AWS-secured data protection is a unique privacy claim that some buyers will appreciate. For users who want a premium smartwatch without subscription fees, the Active 2 is a strong choice.

For buyers who want a premium-looking fitness smartwatch with no subscription fees, the Amazfit Active 2 is our top value pick. The Apple Watch and Garmin alternatives cost noticeably more for similar core features.

9. Garmin Forerunner 55 — Best for Beginners Who Want Garmin Simplicity

The Garmin Forerunner 55 is the best fitness smartwatch for beginners who want Garmin reliability without the complexity of newer AMOLED models. The button-only navigation is a feature, not a bug — you cannot accidentally swipe to the wrong screen during a hard run.

Battery life is the headline: 2 weeks in smartwatch mode and 20 hours with continuous GPS. Reviewers who have used the Forerunner 55 for 3+ years report excellent durability and continued satisfaction. This watch outlasts the trends.

Running Features

PacePro offers race day strategy by suggesting target splits based on the course elevation profile. Race time predictions estimate finish times based on your VO2 max and recent training. Built-in activity profiles cover running, cycling, track run, virtual run, pool swim, Pilates, HIIT, and breathwork.

Display Trade-Offs

The transflective memory-in-pixel (MIP) display is dimmer than AMOLED but easier to read in direct sunlight without backlight. The trade-off is intentional: Garmin prioritized battery life and outdoor readability over color vibrancy. If you train mostly outdoors and want a watch that lasts a full marathon block on a single charge, the MIP display makes sense.

For first-time Garmin buyers and runners who want simple, reliable fitness tracking, the Forerunner 55 is a sensible starting point. Heavy data users should jump to the Forerunner 165.

10. Amazfit Active Max — Best for Strength Training and Marathon Runners

The Amazfit Active Max is the best fitness smartwatch for strength training athletes and marathon runners who want a premium watch without subscription fees. The 3000-nit AMOLED panel is the brightest on our list and stays readable under direct noon sunlight. The 25-day battery is the longest of any AMOLED watch here.

Strength training gets serious attention: 170+ workout modes include HYROX Race, Strength Training with rep counting, and detailed exercise breakdowns. Zepp Coach provides personalized marathon training plans for 3K, 5K, 10K, half, and full marathon distances. The BioCharge metric tracks your daily energy based on heart rate variability, similar to Garmin’s Body Battery.

Maps and Outdoor Navigation

4GB onboard storage holds downloaded terrain and ski maps for offline navigation. The 5 satellite positioning systems cover GPS, GLONASS, Galileo, BeiDou, and QZSS for fast, accurate GPS acquisition. Turn-by-turn directions show directly on the wrist, which is rare at this price. Hikers and trail runners will appreciate not needing a phone in their pocket.

Connectivity and Smart Features

Bluetooth calls work directly from the watch with a built-in speaker and microphone. Zepp Flow hands-free message replies work on Android. iOS users get message notifications but no reply option. The Amazon Music app on the watch is a nice touch for phone-free listening.

Who Should Buy the Active Max

The Active Max is for serious athletes who want maximum battery, premium materials, and comprehensive tracking without subscription fees. Marathon runners, ultra-distance hikers, and strength athletes training for HYROX events will get the most out of this watch. Casual users should consider the cheaper Amazfit Bip 6.

For buyers in the strength training and marathon communities, the Active Max is the best fitness smartwatch in 2026 that does not lock features behind a subscription.

How We Chose the Best Fitness Smartwatches

Our team spent 90 days testing 10 different fitness smartwatches for this guide. Each watch was worn by at least two reviewers across a minimum of 3 weeks. We logged heart rate against a Polar H10 chest strap during steady-state cardio, HIIT, and strength sessions. GPS tracks were compared against a known course measured with a Garmin GPSMAP 67. Sleep tracking was cross-referenced with a Withings Sleep Analyzer mat. Battery claims were tested with always-on display enabled, daily runs, and overnight sleep tracking.

We prioritized heart rate accuracy, GPS precision under tree cover, sleep tracking depth, real-world battery life, and subscription transparency. We weighted these categories equally because a watch that excels in one but fails in another is not useful for daily training. The Garmin Vivoactive 5 took our top spot because it scored consistently high across all five categories without locking features behind a monthly fee.

Heart Rate Accuracy

Optical wrist heart rate sensors have improved significantly since 2023, but accuracy still drops during high-intensity intervals and weightlifting. In our tests, the Apple Watch SE 3 and Garmin Forerunner 265S were the most accurate during HIIT. The Amazfit Bip 6 surprised us with strong steady-state performance at its budget price point. None of the watches fully match a chest strap for rep-counting accuracy during lifting, but the Garmin and Apple watches come closest.

GPS Precision

Dual-frequency GPS makes a real difference in challenging environments. Our tree-cover test showed the Garmin Forerunner 265S tracking tighter paths than single-band watches. Urban canyon runners should prioritize dual-frequency models. Trail hikers benefit from 5-satellite system support, which the Amazfit watches provide at a lower cost than Garmin’s flagship.

Battery Life Reality

Manufacturer battery claims are best-case numbers. With continuous heart rate, sleep tracking, and 3 to 5 workouts per week, expect roughly 70 to 80 percent of the advertised battery life. The Garmin watches held their claims best. The Apple Watch needs daily charging regardless of how light your use is.

Subscription Transparency

Subscription fatigue is real. Whoop 5.0 requires a monthly fee even after paying full hardware price. Fitbit Premium adds AI insights behind a paywall. Garmin Connect+ is optional and not pushy. Amazfit watches have no subscription requirement. We weighted devices that respect your wallet after the initial purchase more heavily in our final ranking.

Fitness Smartwatch Buying Guide: What to Look for in 2026

Choosing the best fitness smartwatch depends on your training style, phone ecosystem, and tolerance for subscriptions. Here are the five criteria our team used to make our final picks.

Smartphone Ecosystem Compatibility

Apple Watch only works with iPhone. Galaxy Watch works best with Samsung phones but pairs with other Android devices. Pixel Watch requires Android. Garmin, Fitbit, and Amazfit pair with both iPhone and Android. If you are an iPhone user, the Apple Watch SE 3 or Series 10 will give you the smoothest experience. Android users should look at Garmin, Fitbit, or Amazfit for the best value. Our 10 best smartwatches under $200 guide has more Android-friendly picks.

Heart Rate and GPS Accuracy Priorities

For runners and cyclists, GPS accuracy matters more than step counting. Dual-frequency GPS watches track tighter paths in tree cover and urban canyons. Single-frequency GPS is fine for open-road runners on a budget. For weightlifters, wrist heart rate accuracy drops during reps, so consider a chest strap for serious tracking.

Battery Life Threshold

If you hate daily charging, look for watches with at least 7-day battery life. Garmin watches lead this category with 11 to 15 days in smartwatch mode. Apple Watch needs nightly charging if you track sleep. Amazfit watches balance AMOLED displays with multi-week battery life. Marathon runners should consider the Garmin Forerunner 265S or Amazfit Active Max.

Subscription vs. No Subscription

Whoop requires a monthly subscription to access any data. Fitbit Premium adds AI insights but the core tracking is free. Garmin Connect+ is optional. Amazfit watches have no subscription. If you want to avoid monthly fees entirely, Garmin and Amazfit are the safest picks. For more outdoor-specific picks, our 10 Best Outdoor Smartwatches guide has dedicated options.

Form Factor: Band, Watch, or Ring

Band-style trackers like the Fitbit Charge 6 are lightweight and slim but have small screens. Smartwatches like the Apple Watch and Garmin Forerunner offer bigger displays and more apps. Rings like the Oura Ring are screenless and focus on sleep tracking. If you want a classic watch look with fitness sensors, our 6 Best Hybrid Smartwatches guide covers that form factor.

Special Features Worth Considering

Sleep apnea detection appears on the Apple Watch SE 3, Series 10, and some Garmin models. ECG capability is available on Apple Watch and Fitbit Charge 6. Women’s health tracking with cycle predictions is strong on Apple Watch and Garmin. Offline maps for hiking are best on Garmin Fenix and Forerunner 265 series, plus the Amazfit Active Max. For shoppers who want a tighter shortlist around a price band, our 10 Best Smartwatches Under $300 Tested Guide breaks down the best options in that range.
