Abstract (en)
[origin: EP2626752A1] The device (30) has a light source (32) which emits a light beam (34), and a light detection system (36). A light-reflecting element (40) projects from one of an upper or lower surface of a wheel (16) of a timepiece mechanism (1). The light source and the light detection system are arranged in a position of the wheel of the timepiece mechanism. The light beam emitted by the light source is reflected by the light-reflecting element in the direction of the light detection system.
