OnePlus Watch 4

Sharper every glance.

Where engineering meets elegance — an all-titanium build with distinctive rivet detailing, offered in two refined colorways: Midnight Titanium and Evergreen Titanium.*

Titanium. Lighter every step.

At just 43g and 11mm, OnePlus Watch 4 is 13% lighter and 6% thinner than its predecessor* — full titanium alloy comfort you'll forget you're wearing.¹

Smarter every answer.

Power meets endurance, smarter. Our Dual-Engine Architecture teams the Snapdragon® W5 with the cutting-edge BES2800. Together, they deliver elite performance for your active life and significantly extended battery life, so you can do more, for longer.

A built-in pace assistant tracks your gap to target in real time, guiding form and effort so you can focus on running — not constantly checking your wrist.

2. Substances with hardness close to that of the screen, such as sand and dust, still exist in daily life and are not entirely scratch-proof. We recommend avoiding severe impacts, drops on granite, concrete, or tiled surfaces during use. Also, avoid scratching, bumping, or scraping with sharp metal objects such as keys and jewelry.

3. Military Standard: Tested and certified for 16 items, including altitude, high temperature, low temperature, temperature shock, solar radiation, rain, damp heat, salt spray, sand dust, immersion, vibration, shock, temperature-humidity-altitude, fluid contamination, acidic atmosphere, and freezing rain.

This means the wearable device can withstand simulated static water pressure at a depth of 1.5 meters for 30 minutes and can withstand high-temperature and high-pressure water jet testing. However, this does not imply that the device is waterproof in water depths of 1.5 meters, nor does it mean it can be used for extended periods in environments with continuous high-pressure water flow.We do not recommend using this product in saltwater or on the beach. Water and dust resistance performance may decrease with prolonged use of the device. Actual performance may vary depending on actual usage and environmental factors.
