    Abstract: Watch comprising a movement, with a timepiece balance wheel comprising a ring distinct from the balance rim, carried by a flange with respect to which this ring is movable in rotation to modify the position of inertia blocks elastically carried by the flange, each able to be indexed in different stable angular positions corresponding to a different inertia of the timepiece balance wheel, the movement further including an operating member movable between coupled and uncoupled positions which includes a stop means for immobilizing the rim in a coupled position, and a control means for rotating the ring to modify the position of the inertia blocks in the coupled position, the watch including a crown controlling the control means, a rotating coupling ring controlling the coupling/uncoupling of the operating member through contactless interaction with an external adjustment tool.

    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.
