Abstract: Device for detecting and synchronising the position of at least one first wheel (16) of a timepiece mechanism (1) for an electronic analogue watch, wherein this first wheel (16) extends in one plane, the detection and synchronisation device (30) comprises at least one light source (32) emitting a light beam (34) and at least one light detection system (36), and this detection and synchronisation device is characterised in that a first light-reflecting element (40) projects from one of the upper or lower surfaces of the first wheel (16) of the timepiece mechanism (1), wherein the light source (32) and the light detection system (36) are arranged so that in a determined position of the first wheel (16) of the timepiece mechanism (1), the light beam (34) emitted by the light source (32) is reflected by the first reflective element (40) in the direction of the light detection system (36).

Abstract: A capacitive sensor to determine instantaneous angular position of a rotatable element in a timepiece, such as a setting stem of a wristwatch. Static electrodes are configured to form, in conjunction with rotor electrodes of the rotatable element, a first differential capacitance pair and a second differential capacitance pair. A sensor calculation unit is configured to sense difference values from the differential capacitances pairs and to evaluate the angular position of the rotatable element from the difference values using predetermined information relating the differential capacitance values to angular position values.

Abstract: A method of detecting a movement of a timepiece setting stem arranged to be moved axially along and/or rotated about its longitudinal axis. The method includes a light source illuminating a portion of the setting stem; a light detector receiving a reflected or diffracted light pattern from the setting stem; a processor forming a first pixel pattern representative of the reflected light pattern at a first time instant; the processor forming a second pixel pattern representative of the reflected light pattern at a second, later time instant; and determining that the setting stem has been moved, if the second pixel pattern is different or shifted with respect to the first pixel pattern.
