Score breakdown
HR fairly close to chest strap; peaks off, ghost steps
Good calls and quick replies; no apps, NFC or swim
About 8-11 days measured, 5 with AOD
Sharp 466x466 AMOLED; daylight visibility only okay
Dual-band GPS matched references; treadmill short, no swim
Aluminium, IP68; thick, heavy, sweaty strap
Each part is rated on one scale for every smartwatch and band, from reviewers' accuracy tests and measured battery life where they exist, what reviewers found, specs and owner reports. It rates the product itself, not how good it is for the price.
Pros
- Bright AMOLED that is easy to read in direct sun
- Fast, fluid software and a tidy Nothing X app
- About eight days a charge with some GPS and calls
- Light for its size; calls are decent with moderate background noise
- GPS locks within seconds, much quicker than the Watch Pro 2
- Sleep tracking caught wake-up times better than a Huawei Watch Fit 3
- Rock-steady connection and notifications on Android and iPhone
Cons
- Bundled strap traps sweat and isn't comfortable
- Treadmill distance consistently short and occasional ghost steps
- No swim tracking despite IP68
- Transcription and news features feel half-done; app needs a login
- Thick (14.4 mm) and fairly heavy
- No swim tracking, NFC, apps or LTE
- Only seven faces can be stored and the charger is proprietary
-
Stylish, smooth and long-lasting; outdoor GPS distance was close to reality but treadmill runs read short, and health readings were not checked against a medical device.

GSMArenaNov 2025
A polished budget watch with fast dual-band GPS lock and dependable tracking; HR results matched a Huawei Watch Fit 3 but were not tested against a chest strap (global model).
-
Long battery and mostly reliable workout data: heart rate on runs and rides tracked close to a chest strap and a pricier watch, with some peak differences (global model).

Free Press JournalJun 2026
A long-term test found GPS distance and recovery heart rate close to reference watches, making it one of the better buys under Rs 8,000, though not a Garmin replacement.
-
FoneArenaMay 2026
A clear step up from the Watch Pro 2 for everyday and casual fitness users; GPS was nearly as accurate as an Amazfit Active 2 and a phone, heart rate good against an oximeter.
