Our take on the OnePlus Watch 3

The OnePlus Watch 3 is a stainless-steel smartwatch with a 1.5-inch AMOLED screen, always-on display and sapphire glass. It runs a dual-engine setup with a Snapdragon chip and a low-power co-processor, so it can last days between charges while still tracking GPS workouts, heart rate and sleep. It is rated 5 ATM for swimming and has a barometer, compass and gyro. The best new price is $259.99 at eBay as of November 4, 2026, and three stores list it new.
