Accutron's Proprietary Electrostatic Movement. The electrostatic energy is created by twin turbines that rotate as a result of human motion at incredible speeds between two electrodes affixed to the movement. The energy, stored in an accumulator, powers two motors; a world’s first electrostatic motor fuelling the fluid second hand and a step motor powering the hour and minute hands. Power saving function: To ensure power saving, the second hand automatically stops at 12 o'clock after 5 minutes of non activity. Your timepiece continues to keep time, the hour hand and the minute hand keep moving. When you would like to see the second hand's motion, please swing arm fully up and down for 3 to 5 seconds.
