ABSTRACT:
Disclosed is a solid state watch having an electro optical display which is selectively actuated by a gravity switch contained in the watch casing and positioned such that upon a displacement from a horizontal of the watch the display is actuated. A preferred embodiment utilizes a triangular-shaped cavity having a ball-shaped conductor movably contained therein for engaging a pair of electrical contacts within the cavity for coupling power to the display. Furthermore, the displacement of the watch from horizontal must also be within a selected orientation range.
