It is based on an ATmega running with internal 8MHz clock and external 32kHz crystal for keeping the time (RTC). The code and system have been tweaked to lower the power consumption as much as possible. The watch currently uses about 1.2uA in idle (non-display) mode and about 13mA when displaying the time. With a 200mAh regular CR2032 battery you should get 2-3 years of use!
