Device for detecting an angular reference posititon of a rotary member in a watch movement.

摘要

The invention relates to a device (10) for detecting a reference position of a wheel or a disc of a watch movement, as well as a method for detecting a reference position of a wheel or a disc of a movement. watchmaker. This device comprises at least a first rotary member (20) and an electromechanical switch configured to be in a first position when a passive zone (22) of the first member makes electrical contact with a passive zone of a second rotary member (40) and to be in a second position when a neutral zone (24) of the first member is in contact with the second member. In one embodiment, a device as disclosed can be placed in a quartz watch to detect and act on the position of one or more hands, for example the second hand, the minute hand, etc.
