Abstract

The drive serves as a quartz clock mechanism (3). The second shaft (20) of the quartz clock mechanism is connected to a spring element (17) for compensating for shocks and catches of the shaft. The spring element transfers the drive force of the mechanism to a rotatably mounted coupling wheel (18). The coupling wheel forms a selectable transmission between its star teeth and those of a drive pinion (12) which is pressed into a drive tube (9). The drive tube acts directly or indirectly on the housing body (1).
