The Oppo Watch X3 is a new high-end smartwatch packing a bright LTPO OLED display and extended battery life. Available in three colours, the Watch X3 is compatible with Android and iOS devices too.

Oppo has just launched the Find N6 in its home market. At the same time, the company has also presented the Watch X3. Again, Oppo has only launched the Watch X3 in China so far with no word on global availability. With that being said, the Watch X2 is available globally running Wear OS as an alternative to the Pixel Watch 4 and Galaxy Watch8 (curr. $207 - refurbished on Amazon).

By contrast, the Watch X3 comes pre-loaded with ColorOS Watch 16.0 in China. Also, the smartwatch is compatible with devices running Android 10 or iOS 14.0 and newer. A digital crown and a solitary hardware button occupy the Watch X3's right-hand side, just like its predecessor.

The Oppo Watch X3 is 11 mm thick and weighs 43 g excluding a watch strap.

Oppo installs a 1.5-inch LTPO OLED display too that resolves at 466 x 466 pixels with a 60 Hz refresh rate. While the company mentions 3,000 nits peak brightness, this is only true in direct sunlight when a sports mode is running. Normally, the Watch X3 can only be manually adjusted up to 600 nits.

Meanwhile, the included 646 mAh battery is said to last up to 5 days in smartwatch mode. The Snapdragon W5 chipset should help the Watch X3 run to 16 days of battery life in power-saving mode, though. The Watch X3 also promises a suite of health monitoring sensors, including ones dedicated to taking an ECG and checking skin temperature. Oppo charges CNY 2,799 (~$405) for the Watch X3 in a choice of black, orange and titanium finishes.
