Abstract: A push-piece winding button control device is for a portable object of small dimensions. This device includes a pivoting control stem axially movable between at least a transitory first position and a stable second position. The device further includes a position indexing plate arranged to be integral in translation with the control stem, while keeping the same orientation relative to the frame. The device also includes a cam follower arranged to cooperate with a longitudinal cam path formed in the position indexing plate. The cam path includes a recess defining the stable position of the control stem, and a ramp-shaped profile portion which rises from the recess towards the transitory position.
Abstract: A watch case includes a case middle, a bezel, and an external element at least partially disposed between the case middle and the bezel. The bezel includes at least one hollow revealing the external element. The external element is attached directly to the case middle, independently of an attachment of the bezel to the case middle.
Abstract: A device for attachment of a timepiece movement to a watch case, including a peripheral attachment element of the movement positioned in abutment on an axial bearing surface of the case. The device includes thermoformed studs integral with the case having a mushroom shape at an end thereof providing an axial retaining surface acting as a rivet to hold the peripheral attachment element of the movement against the axial bearing surface of the case.

Abstract: Method for forming an assembly of elementary timepiece components, each available in different colored variants, wherein at least some of said different elementary components are the same color as each other, characterized in that a random selection of each said elementary component is made until said complete assembly is obtained, so that at least two elementary components are of different colors.
Abstract: Device for electromechanical watch (1) allowing an electronic control circuit of the watch (1) movement to determine the moment at which and the direction in which an indication showing a magnitude of time has to be corrected, said device including a wheel (68), which is driven by the watch (1) movement and carries means (70, 72) for actuating first and second detection means (46a, 46b) connected to the electronic control circuit, said electronic control circuit deducing, from the moment at which and the order in which the first and second detection means (46a, 46b) are actuated by the means actuating the wheel (68) driven by the watch (1) movement, the direction in which the wheel (68) is being driven by the movement at the moment when the magnitude of time has to be respectively incremented or decremented.
