Is the OnePlus Watch 3 46mm worth it?
Yes — the longest-lasting Wear OS watch.
It runs full Wear OS with Google's apps, yet lasts about four to five days between charges, more than twice most rivals, because a second low-power chip runs the basics. The screen is sharp and bright, the crown now scrolls, GPS is dual-band and the titanium-framed case is built to military toughness standards. It costs less than a Pixel Watch. It comes in one big 46mm size (a 43mm version is sold separately) with no LTE, the always-on screen cuts battery to about two days, and it doesn't work with iPhone.
Good to know
- Battery drops to about two days with the always-on screen.
- One big 46mm size, with no LTE option.
- No fall, crash or sleep apnea detection.
- The charger only fits one way round.
- About four to five days of battery

How we reached this verdict
Tom's Guide (4.5/5) got four days and six hours from it, calls it a premium, well-priced Android watch, and notes there's only one size and no fall or crash detection. Trusted Reviews (4.5/5) calls it the new king of Wear OS, for its 120-hour battery, tougher build, multiband GPS and a crown that finally scrolls.
We compared independent expert reviews with the manufacturer's specifications, then checked it's sold at a major retailer where you live. We don't test products ourselves.
