The OnePlus Watch 2R is a lightweight, budget-friendly smartwatch that offers a compelling blend of performance and battery life, positioned as a more affordable alternative to the OnePlus Watch 2.
It features a 1.43-inch AMOLED display with a resolution of 466 x 466 pixels and a maximum brightness of 600 nits (1000 nits in high brightness mode).
The watch is powered by the Snapdragon W5 Gen 1 and BES2700BP chipsets, delivering top-tier performance and smooth operation on Wear OS 4.
It boasts up to 100 hours of battery life in Smart Mode, extending to 12 days in Power Saver Mode, and supports fast VOOC flash charging.

The device is constructed with an aluminum alloy chassis and a fluororubber strap with a stainless steel buckle, making it significantly lighter than its predecessor—weighing approximately 37g without the strap and 59g with it, compared to the Watch 2's 49g and 80g respectively.
It features IP68 and 5ATM water resistance, suitable for swimming and diving up to 50 meters.
