OnePlus made its smartwatch debut with a bold promise: premium design, 14-day battery life, and advanced health tracking — all under $160. After years of rumors, the OnePlus Watch finally arrived. Here's everything you need to know before buying one.

Design

The OnePlus Watch features a 1.39" round AMOLED display with a 2.5D curved glass and a glossy CD-pattern finish that gives it a distinctly premium, analog watch feel. It's reminiscent of the Samsung Galaxy Watch Active 2 in form — round face, rubber strap, two side buttons — but the bold AMOLED screen and refined watch faces help it stand apart.

The standard 22mm silicone band fits universally, and the two right-side buttons make it easy to navigate workout modes without touching the screen. This is a proper smartwatch, not a fitness band.

Operating System (RTOS)

The OnePlus Watch runs a proprietary Real-Time Operating System (RTOS) — not Android Wear. Similar to Amazfit's approach, RTOS prioritizes speed, battery efficiency, and reliability over app flexibility. The interface is responsive and easy to navigate: change settings, switch watch faces, toggle fitness modes, and control music all from the wrist. For phone-free music, you'll need to transfer files from your computer to the watch directly.

Fitness & Health Tracking

OnePlus packed serious health features into this watch:

• 110 workout modes + 15 professional fitness modes
• SpO2 sensor for blood oxygen monitoring
• 24/7 heart rate monitoring with stress detection and abnormal pattern alerts
• Built-in GPS for outdoor tracking — cycling, running, hiking
• 5ATM / IP68 rated — swim-proof and built for the elements
• Calorie burn, workout duration, and activity tracking via the OnePlus Health app

Connectivity

Bluetooth 5.0 BLE keeps the watch connected to your smartphone for notifications, calls, and music control. A standout feature: the OnePlus Watch can pair with OnePlus TVs and act as a remote — volume, channel, power, and basic controls all from your wrist. Pair it with Bluetooth earphones and you have a fully phone-free navigation and music experience.

Battery Life

OnePlus claims up to 14 days on a single charge — a figure that puts it well ahead of Apple Watch and Samsung Galaxy Watch in endurance. The 402mAh battery sits between the Galaxy Watch 3 (340mAh) and Galaxy Watch (472mAh), but the RTOS efficiency makes the difference. Fast charging gets you to 50% in 15 minutes and fully charged in under 30 — a genuine advantage for anyone who hates downtime.

Cobalt Limited Edition

For those who want something more luxurious, the OnePlus Watch Cobalt Limited Edition features a stainless steel and cobalt alloy body (twice as durable and corrosion-resistant), a sapphire crystal scratch-resistant display, and a green leather strap with a golden cobalt finish. The specs are identical to the standard model — the upgrade is purely in materials and aesthetics.

Final Verdict

If you're an Android user looking for a smartwatch under $160, the OnePlus Watch is one of the best value options available. The 14-day battery, fast charging, 110 workout modes, and clean design make it a compelling choice — especially if you're already in the OnePlus ecosystem.
