A moon phase display mechanism driven by a horological movement, this moon phase display mechanism including a transparent support provided with an upper face and a lower face which extends at a distance from the upper face, a representation of the Moon being transferred, for example by printing or by engraving, to one of the upper or lower faces of this transparent support, a substrate being disposed under the transparent support, at a distance therefrom, the moon phase display mechanism also including a shutter which is driven by drive means moved by the horological movement and which is arranged so as to displace between the transparent support and the substrate, the shutter and the substrate having display contrasts which are inverted relative to each other.

Moon phase display mechanism

An optical device including a transparent support provided with an upper face and a lower face which extends at a distance from the upper face, the transparent support forming a lens of plano-concave shape delimited on a first side by a planar surface, and delimited on a second side, opposite the first side, by a concave surface, the optical device also including a shutter which is disposed under the concave surface of the transparent support, at a distance therefrom, the optical device finally including a substrate disposed after the shutter.

Optical device allowing to create optical aesthetic and technical effects

A back () for a watch case (), the back () including a first element () arranged so as to be screwed onto the watch case (), and a second element () including an end face bearing a pattern (M), the second element () being mounted such that it can move in rotation about an axis (C) passing through the centre of the case (), wherein the second element () has a brake arranged so as to hold same relative to the first element () in different angular positions about the rotational axis (C), the brake being disposed between the first and second elements ().

Orientable back for a timepiece

Device () for displaying a magnitude on an oscillating weight () for a self-winding timepiece movement () comprising a means () of displaying said magnitude by comparison to a complementary display means (). Said display means () pivots coaxially to said oscillating weight (), and is subject to a general pivoting motion resulting from the combination of a first pivoting motion synchronous with that of said oscillating weight (), and a second pivoting motion resulting from said display means () being pivoted by said movement () relative to said complementary display means () integral with said oscillating weight (). Oscillating weight () including such a device (). Self-winding watch including an oscillating weight () comprising such a device (), and whose motions are transmitted to a mainspring of said watch.

Display on the oscillating weight of a self-winding movement

A universal watch including a movement driving a main display means cooperating with a complementary main display means, a means for adjusting the main display means to set the time of a determined place, a secondary display means which is moveable relative to the complementary main display means, and comprises geographical reference points of different time zones. This movement drives synchronously with the main display means the secondary display means, and a structure carrying first screens, each superposed on a geographical reference point and, according to the time of day, changing position under the action of a drive torque from drive means which is greater than the resistant torque imparted thereon by friction means connected to the structure.
