We don't talk about the original OnePlus Watch very much. At least, not kindly. But instead of slinking back into the smartwatch shadows, the firm's defiant second attempt met critical acclaim: the styling was striking and functionality much improved, but it was the seriously impressive battery life that made it stand out from the Wear OS competition. And the new OnePlus Watch 3 aims to capture that magic again.

With more of a fitness focus, the Watch 3 has all the usual sensors but can also track blood oxygen, measure your vascular health, and perform an ECG scan (or will when the tech is approved).
