Design]The frame is precisely designed by a five-axis CNC machine.It can provide maximum protection for the watch. We designed the side crown as a red sports car wheel to bless your passionate life. You may start your healthy life by pressing the “wheel”. [Functions] Equipped with 10 sports modes, its functions include HR and BP monitoring, sleep monitoring, steps, calorie, speed, distance, GPS track record, heart rate alert, messages, alarm, timer, countdown, music control, stand-up alert, disconnection alert, and remote shutter. [Chic] An artificial gemstone with better transparency is used as its screen. As thick as 0.047 inches, the screen can give you better touch experience and visual effects.It allows you to switch between “digital dial” and “indicator dial” directly, and you may adjust the screen brightness and screen-on duration (maximum: 30 seconds). And you can set the “wrist rotation screen-on” sensitivity to get better user experience. [Endurance] In normal conditions, it can be used for 7-10 days and stand by for over 30 days. If the functions, “messages” and “wrist turning screen-on”, are disabled and only the functions, “clock” and “steps”, are used, the battery life will be greatly extended. The battery life of the smart watch will be lowered if the “24-hour HR and BP monitoring” is enabled, so you may enable or disable it at will.
