The OnePlus Watch 2 is rumored to be officially unveiled at Mobile World Congress, running Wear OS 4 and featuring a 1.43-inch AMOLED display with a Qualcomm Snapdragon W5 Gen 1 chipset. This marks a significant departure from its predecessor, the original OnePlus Watch, which ran on a proprietary OS. The move signals OnePlus' entry into the Wear OS ecosystem, following the footsteps of Xiaomi's Watch 2 Pro, and is expected to bring heightened anticipation in the smart wearables industry.
