COLMI V23: A cheap smartwatch with multiple sensors and IP67 certification

The COLMI V23 is a cheap yet stylish smartwatch that is available in multiple styles. The V23 costs between US$27 and US$38 depending on the style chosen, but all come with a 1.28-inch IPS screen that resolves at 240 x 240 pixels. The display is a touchscreen, too. The smartwatch weighs 41 g, while the watch face is around 10.5 mm thick. 

COLMI has equipped the V23 with an RTK8762 processor, along with Bluetooth 5.0 connectivity. According to the manufacturer, the smartwatch should be compatible with Android 4.4 and iOS 8.0 or newer. When paired to a smartphone, the V23 can display notifications, control music playback and act as a remote camera shutter.

The V23 supposedly has a heart rate monitor and possesses blood oxygen and oxygen saturation monitoring capabilities. The accuracy of these sensors is unknown though as COLMI has not specified which sensors it has used. Similarly, the V23 can be used as a pedometer and to measure sleep quality.

Additionally, the smartwatch is IP67 certified and has a 200 mAh battery. Finally, the V23 supports seven sports modes, but COLMI has not included a GPS module. The COLMI V23 is available to order from AliExpress and Gearbest via the links below.
