OnePlus Watch 3 could eclipse the Apple Watch Ultra 3 with the ‘holy grail’ of smartwatch health tech

Chinese manufacturer Oppo, which also makes the OnePlus series of Android phones and wearables, looks set to introduce a new watch next month, likely the OnePlus Watch 3. A promotional image, shared on Weibo by OPPO product manager Zhou Yibao, shows a cool new function: blood pressure monitoring, which indicates the risk of hypertension.

Accurate blood pressure monitoring via LEDs remains a ‘holy grail’ health feature for even the best smartwatches, and is proving frustratingly out of reach. The Huawei Watch D2 is the most accurate yet, including in its technology a belt full of inflatable bladders, which acts as a wearable blood pressure cuff.
