The B57 is a budget smart watch with a 1.3-inch 240x240 IPS color screen, a 130mAh battery and a 4MB body memory. It covers the basics: step counting, all-day heart rate, blood oxygen and blood pressure readings, sleep and sedentary reminders, call and message notifications from apps like WhatsApp and Facebook, music control and weather. It suits shoppers who want notifications and health stats on the wrist without paying for a name brand. Against rivals at this level it has a small battery and a basic sensor set, and its health readings are estimates rather than medical-grade measurements.

It also shows call, SMS and social app notifications with the sender's name and content, including QQ, WeChat, Facebook, WhatsApp, Twitter and Skype.
Other functions include three alarm clocks, a sedentary reminder, a find-the-bracelet feature, do not disturb mode, raise-to-wake screen, three clock faces, music control, weather display and long press to reject incoming calls.
