Abstract: The invention relates to a skeleton watch including: a case middle; a movement including: a frame; time display means; a reduction mechanism meshed with the time display means; a motor including: an electromagnet; a stator; a rotor bearing a pinion meshed with the reduction mechanism; an electronic circuit including: a piezoelectric quartz; a control circuit connected to the quartz and to the stator by means of electrical conductors; an additional plate which carries the electronic circuit, said additional plate being distinct from the back cover and fixed to the frame.

Abstract: The present invention concerns a push-piece winding button control device 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, wherein said 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, and wherein the device further comprises 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: The invention concerns a device for controlling at least two electronic and/or mechanical functions of a portable object of small dimensions, this device including a control stem (4) which is axially movable between at least a first and a second position, this control stem (4) being provided at a first end (6) with an actuation member (8), and being provided towards a second end (10) with a position indexing plate (58) arranged to cooperate with an elastic member (80) in order to match each of the first and second positions of the control stem (4) with one of the mechanical or electronic functions.

Abstract: Portable object comprising a frame arranged to serve as a cradle for a control stem, the actuation in rotation of which makes it possible to control at least one electronic or mechanical function of the portable object, a magnetized ring being driven in rotation by the control stem, the rotation of the magnetized ring being detected by at least one inductive sensor disposed inside a housing of the frame inside which the inductive sensor is held by elastic means.

Abstract: The present invention concerns an electronic timepiece with two analogue type hands. The timepiece includes an hour hand and a minute hand, the hour hand and the minute hand being arranged to operate independently of each other. The hour hand and the minute hand are arranged to operate in a first operating mode and in a second operating mode, which is arranged to be actuated by the timepiece detecting an event. In the second operating mode, the hour hand and the minute hand are arranged to operate in a different manner from their mode of operation in the first operating mode.

Abstract: A portable electronic device includes at least one electronic module and the electronic module includes, in particular, a main plate provided with a cavity arranged for receiving an electrical energy source, at least one movement associated with a printed circuit, an elastically deformable contact member for ensuring an electrical connection between the electrical energy source and the printed circuit, and a holder for holding the electrical energy source. The holder includes a removable holder made of insulating material arranged to receive the energy source and including a removable clamp for holding the energy source in place. The holder can be inserted inside the cavity.

Abstract: An electronic clock mechanism includes an analog display device including a ring of dates and a stopwatch hand associated with a graduation of a small counter. The ring and hand are driven by a same electric motor via a permanent gear train, the hand being mounted on a wheel of the permanent gear train, the wheel arranged between a motor pinion and a movable element including a date driving wheel. The ring and date driving wheel respectively include two sets of teeth forming a permanent gear having a relatively large clearance to define a dead angle region for the date driving wheel as the ring is positioned by a jumper. The dead angle region is used to drive the stopwatch hand independently of the ring. The permanent gear train is arranged such that torque for positioning the rotor creates for the date driving wheel a blocking torque for shock-resistance.
