Abstract: A Moon phase display mechanism comprises a Moon, a mask, and a drive device arranged in such a way that the mask and the Moon move, during each lunar cycle, in the following sequence: a) with the Moon and the mask both located in an initial position, in a new Moon configuration, the Moon is driven to progressively disengage from the mask, until it is positioned in a final position in the middle of a given lunar cycle, in a full Moon configuration, b) the mask is driven to cover the Moon, until it is positioned in the final position at the end of the given lunar cycle, in a new Moon configuration, and c) the Moon and the mask are driven to rapidly return to their initial positions, in a new Moon configuration.

Abstract: Disclosed is a display device for a timepiece movement including: an hour display wheel for a predefined time zone; and a chassis pivotable to cooperate with indications that are static relative to the frame of the timepiece movement to display information, the respective angular positions of the chassis and of the hour display wheel being indexed relative to each other so the angular position of the chassis is associated with the display of information relating to the predefined time zone. The device further includes a selection mechanism arranged: to rotate the hour display wheel, responsive to a predefined action by a user, between first and second positions associated with respective first and second time zones; and to simultaneously rotate the chassis in steps so that the chassis moves from a first position, associated with the first time zone, to a second position, associated with the second time zone.

Abstract: A regulating device for a watch movement has an oscillator including at least a first and a second balance. Each balance has an inertia wheel and a balance staff. The oscillator includes at least one elastic member intended to maintain the oscillations of the oscillator. The latter also has a gear train comprising at least two mobiles. The inertia wheel of each balance is fixed in rotation to a mobile of the gear train. The gear train connects the inertia wheels of the first and second balance by a desmodromic link so that the respective oscillations of the first and second balances are in phase opposition. The regulating member further has an escapement including at least one escapement wheel and at least one anchor intended to regulate the at least one escapement wheel and to maintain the oscillations of the oscillator. A method of adjusting the frequency of the oscillator of the regulating member.

Abstract: A miniature, self-powered, user-powered lighting device, employing mechanical energy storage and incorporating miniature lighting elements which are illuminated on-demand for a limited duration for backlighting or illumination purposes without the need for a battery or other electro-chemical storage device. The device comprising a manual spring loading mechanism, a spiral spring, a manual trigger mechanism, a transmission for increasing the rotational speed, a miniature generator, and at least one light source.
