The OnePlus Watch 4 is OnePlus's latest smartwatch, packing premium materials and solid software into a lightweight titanium package. It launched globally in 2026 as one of the first watches to ship with Wear OS 6 straight out of the box, which is a pretty big deal for Android wearable fans.
Overview
Built from high-grade titanium alloy, the Watch 4 is 13% lighter and 6% thinner than its predecessor, clocking in at just 43g without the strap. The 1.5-inch LTPO OLED display hits up to 3,000 nits peak brightness and is protected by Sapphire Crystal glass. It runs OxygenOS Watch 8 on top of Wear OS 6, with Google Gemini baked right in for quick voice tasks.
