Disclosed is a solid state wristwatch of relatively small size useful as a small man's watch or even a ladies' watch. It incorporates an arm responsive inertial switch for energizing a light emitting diode display. The display forms part of a timing module and is mounted on one side of a laminar ceramic substrate. Mounted on the other side of the substrate is a combination timepiece and calendar circuit chip. Printed circuits are formed on non-contacting surfaces of the substrate laminations and interconnected by conductive pins. The entire timing module is staked to a plastic frame which also carries the watch batteries, quartz crystal, trimmer capacitor, switches, or other watch components.

Disclosed is a solid state wristwatch of small size particularly adapted for use as a ladies' watch. A plurality of small individual display stations formed of light emitting diodes are mounted on one side of a laminar ceramic substrate. The stations are viewed through a window formed of hardened red glass arcuately curved in the direction of the long dimension of the display. The watch case or bezel is similarly curved to conform to the window providing a more pleasing appearance and to conserve space.

Solid state ladies' wristwatch

Disclosed is a solid state wristwatch having an active electro-optical display in the form of light emitting diodes. The display is mounted on one sloping side of a groove in a circular module frame and comprises a ceramic substrate having the display on one side and a large scale integrated circuit on the other. The angular orientation of the display coincides with the axis of an angularly oriented viewing window constructed so that the watch case shades at least part of the display. Viewing under bright daylight is enhanced and through ambient light responsive control of current to the display, battery energy under most viewing conditions is conserved.
