OnePlus has formally introduced its inaugural smartwatch alongside its new 9-series flagships. The wearable has a round case made of "surgical-grade" stainless steel, or a special alloy in its limited-edition Cobalt version. The OEM claims its 402mAh battery can last for up to 2 weeks, and charges using its in-house Warp technology.
