ABSTRACT:
This invention relates to a solid state timepiece and more particularly to an electronic watch which employs no moving parts. In the present invention a frequency standard in the form of a crystal oscillator acts through a solid state electronic circuit divider and display actuator to power in timed sequence the light-emitting diodes of an electro-optic display. Low cost, low power consumption and small size and weight are achieved through the use of a charge coupled binary divider chain.
