Abstract
A timepiece has a wheel and pinion mechanism having upper and lower shafts rotatably mounted in bearings which are fixed in a pair of spaced apart plates. The bearing fixed in one plate has a cylindrical portion which surrounds the pinion portion of the wheel and pinion mechanism and which is spaced therefrom a slight distance which is sufficiently small to enable the pinion portion to abut the inner wall of the bearing cylindrical portion in the event the wheel and pinion mechanism tilts on its lower shaft a predetermined amount from its intended orientation thereby preventing falling of the mechanism during assembly.
