The OnePlus Watch lineup has evolved dramatically since the original model launched in 2021. From a promising but flawed RTOS-based debut to a full Wear OS powerhouse with the OnePlus Watch 2 and beyond, the journey has been remarkable. This guide covers every OnePlus Watch model, their specs, and how they compare in 2026.
The Original OnePlus Watch (2021)
The first OnePlus Watch launched with a circular 1.39-inch AMOLED display, 46mm stainless steel case, and a claimed 14-day battery life. It ran on a custom RTOS instead of Wear OS, which limited app support and smart features. Despite impressive build quality and smooth performance for basic tasks, the lack of third-party apps held it back.
Key specs included IP68 water resistance, continuous heart rate and SpO2 monitoring, GPS tracking, and Warp Charge fast charging. For more on smartwatch alternatives, check our Huawei Watch GT 2e review for comparison.
OnePlus Watch 2 – The Wear OS Revolution (2024)
OnePlus addressed the biggest complaint with the Watch 2 by switching to Wear OS 4, powered by a dual-chip architecture. The Snapdragon W5 Gen 1 handles demanding tasks while a smaller BES2700 co-processor manages always-on display and basic notifications for efficiency. This gave the Watch 2 both full smartwatch capabilities and strong battery life.
It retained the circular 1.43-inch AMOLED display, added a rotating crown, and improved fitness tracking with dual-frequency GPS. Running Google services natively meant support for Google Maps, Google Assistant, WhatsApp replies, and thousands of Play Store apps.
OnePlus Watch 2R – The Affordable Option
Released alongside the Watch 2, the 2R is a lighter, more affordable variant with an aluminum case instead of stainless steel. It shares the same dual-chip Wear OS platform, display quality, and fitness tracking, making it one of the best value Wear OS watches on the market.

OnePlus Watch 3 and Beyond (2025-2026)
The OnePlus Watch 3 continued refining the formula with upgraded sensors including a more accurate heart rate monitor and temperature sensor. Battery life improved further, and OnePlus added advanced running metrics like VO2 max estimation and recovery time recommendations.
Rumors suggest a OnePlus Watch 4 could feature a micro-LED display and even tighter integration with the OnePlus ecosystem, including camera shutter control for OnePlus phones and seamless audio switching with OnePlus Buds.
