Abstract

A gear train mechanism for a wristwatch provides a thinner watch, the gear train comprising a frame plate, a dial, a plate interposed between the dial and the frame plate, and a shaft rotatably supporting a center wheel and pinion. The shaft is attached to the frame plate. Rubbing and misalignment of the hands is prevented by aligning their rotating support members for an extended longitudinal distance on the shaft. This is accomplished by the gear train of this invention despite a reduction in the thickness of the watch. Hour and minute hands or hour, minute, and second hands are provided in alternative embodiments.
