OnePlus announced the OnePlus Watch 3 on February 18, 2025, and opened preorders that day; the company’s stated date for open sales was February 25. February 18 was not a universal delivery date. The watch pairs a substantial design with Wear OS 5 and ambitious battery claims, but those figures come from OnePlus, and reviewers did not treat it as an automatic best-in-class choice.
When did the OnePlus Watch 3 come out?
OnePlus dated its launch announcement February 18, 2025, and said the watch launched in the United States and Canada. Its community announcement specified the retail schedule: preorders began February 18, with open sales scheduled to begin February 25. Wareable also reported February 25 availability at launch.
| Milestone | Date | What it means |
|---|---|---|
| Announcement and preorder start | February 18, 2025 | OnePlus announced the watch and began accepting preorders. |
| Scheduled open sales | February 25, 2025 | OnePlus said general sales would begin; this was not a promise that every preorder would arrive that day. |

What makes the Watch 3 look distinctive?
The 46mm Watch 3 is a large smartwatch, with titanium construction and a sapphire crystal cover highlighted in TechRadar’s launch-period review. Those materials and the case size help explain the premium, substantial look—but wrist fit is personal, and the 46mm case may feel oversized on smaller wrists. Later coverage also identifies a 43mm Watch 3, so check the exact model and dimensions before choosing a listing or band.

TechRadar discussed the construction and size as part of its review; the impression that the watch “looks great” is subjective rather than a measurable product fact. The linked launch coverage concerns the 46mm model: TechRadar’s OnePlus Watch 3 review.
How long does the OnePlus Watch 3 battery last?
OnePlus advertised up to five days in Smart mode, up to 16 days in Power Saver mode, and a full day’s use after a ten-minute charge. These are manufacturer estimates, not independent test results. Actual runtime can vary with settings and use, and the two modes describe different feature trade-offs; the figures should not be treated as a like-for-like comparison with another watch unless that model was tested under comparable conditions.

It may suit someone who wants a large 46mm Wear OS watch, values the materials and design, and finds OnePlus’s battery modes appealing. It is less straightforward if you need a smaller case or are choosing chiefly for a guaranteed battery advantage: the advertised durations are estimates, and the available review coverage does not establish a controlled battery comparison against competitors.

Wareable’s review regarded the Watch 3 as an iteration and concluded that its improvements did not put OnePlus among the best Wear OS smartwatch options. That is the reviewer’s assessment, not a universal verdict. Compare the watch against alternatives on the factors that matter to you:
- Fit: Confirm whether you are considering the 46mm or 43mm model and check the listed dimensions.
- Software: Consider Wear OS 5 and the apps and features you actually need.
- Battery: Compare estimates or tests using the same usage conditions and mode, rather than relying on a single headline number.
- Materials: Weigh the appeal of titanium and sapphire against the watch’s substantial size.
- Price and availability: Check current listings; launch announcements and 2025 reviews do not establish today’s price, stock, or software-support status.
