ABSTRACT:
A watch assembly is disclosed which includes a watchcase that has frames along opposite sides which define the perimeter of the watchcase platform on which is mounted a crystal having at least one opening which receives a rocker switch for controlling watch functions. The recess formed by the opening in the crystal when the crystal is attached by adhesion substantially to the entire top surface of the watchcase platform has at least one hole at the bottom of the recess to provide for the rocker switch to have access to at least one switch contact inside the case. The rocker switch includes a manually-operated actuator arm disposed in the recess and having at least one projecting leg extending through at least one hole in the platform in the watchcase to actuate at least one switch contact mounted on a timekeeping circuitry module inside the case. Resilient washers which are disposed about the legs of the actuator arm seal off the inside of the watchcase from the outside of the watchcase when the rocker switch is properly seated in the recess. The resilient washers also provide for spacing and for return of the actuator bar to its original position after it is pressed.
