Launch details
OnePlus opened pre-orders for the Watch 3 in February 2025 at $329.99 in the US (£319 in the UK, according to Tom's Guide). Android Central notes that US shipping slipped to April 2025 because of a typo printed on the case. The reviewed model comes in one size (46.6 x 47.6 x 11.75 mm) and runs Wear OS 5 on a Snapdragon W5 chip, paired with a low-power BES2800 chip that handles lighter tasks. TechRadar says a smaller model was announced later.
What reviewers agree on
- Battery: Tom's Guide got 4 days 6 hours in smart mode, TechRadar about 4.5 days with several GPS workouts, and Android Central 4–6 days with the always-on display.
- Apps: thanks to Wear OS, it runs Google and third-party apps like any other Android watch.
- Design: a classic round look with a bright OLED screen; Android Central calls its haptic crown the best on any smartwatch.
- Health tracking: heart rate, blood oxygen, wrist temperature and sleep are all wellness features, with a quick 60-second health check.
- Size: all three outlets find it big, and there is no LTE version.
Where opinions differ
| Topic | Favourable view | Reserved view |
|---|---|---|
| Health | Tom's Guide likes the wide range of metrics, including arterial stiffness. | Tom's Guide regrets the lack of sleep apnea, fall and crash detection. |
| ECG | The ECG feature exists on the watch. | TechRadar and Android Central note it is not available in North America. |
| Sport | Android Central praises accurate heart rate and no subscription. | TechRadar found swim stroke detection inconsistent and sleep scores hard to read. |
| Updates | It launched on a current version of Wear OS. | Android Central points out only two OS updates are promised. |
Verdict
The OnePlus Watch 3 is the pick for Android users who want real multi-day battery life without giving up Wear OS apps. If you have small wrists, need LTE or sleep apnea detection, look at a Samsung Galaxy Watch instead, such as the models in our Galaxy Watch 9 analysis.
