Watch movement with a drive mechanism of an analogue indicator with periodic or intermittent movement.

摘要

The watch movement (24) is equipped with an analogue display device for information whose value varies periodically or intermittently, this analog display device comprising on the one hand an indicator (26) provided with a first toothing (28) and, on the other hand, a periodic or intermittent drive mechanism (30) for this indicator (26). The drive mechanism (30) is formed by an irreversible transmission system which has an anti-shock function for the indicator (26). The display device further comprises a jumper (56) for positioning this indicator (26) which generates a positioning force on the first toothing (28), which is sufficient to accurately position this indicator (26) in a plurality of positions. discrete display positions but largely insufficient to provide a shockproof function for the indicator (26). Thus, the indicator (26) can be driven with a relatively low torque, which therefore requires less energy and makes it possible to provide a drive mechanism with a smaller reduction in the transmission of the engine torque.
