Abstract
A case-back of an electronic timepiece is provided with a means to detect whether said timepiece is on a human arm or not. When the timepiece is put on the arm, said detecting means operates a switching means to enable a display. When the timepiece is taken off the arm the display is not operated, so the consumption is reduced and the battery is saved.
