Micro USB is also used to charge lithium-polymer battery of 300mAh. With 300mAh battery and daily active time of 30min autonomy of 10 days should be possible. There are also RTC chip with alarm function, accelerometer, ambient light sensor, piezo transducer and hall effect switches to replace mechanical switches. Small neodymium magnet on the side of the watch is used to activate hall switches and emulates the look of “Crown” of mechanical watches.
