Abstract

PURPOSE: To reduce both the size and thickness of a watch, by setting the lengthwise measurement of a liquid crystal cell almost equal to the length of a movement in the shorter diameter direction and at the same time setting the sum of the diameter of a battery and the length of a coil core substantially equal to the measurement of the movement in the shorter diameter direction.
CONSTITUTION: A train wheel block 2 is set at nearly the center part of a liquid crystal support frame 1. A liquid crystal device 3, i.e., an electronic optical display device is set at an end of the longer diameter direction A of the watch movement. At the same time, a battery 4 and a step motor 5 are set at the other end and contiguously to the block 2. On the other hand, a switch block 6 is provided as if it were enclosed by the block 2, the device 3 and the step motor 5. Furthermore a quartz oscillator and a buzzer driving booster coil 9 forming an electronic circuit block 7 is set between the block 2 and the device 3.
