Timepiece wheel set () including a first guide surface () cooperating with a second guide surface () associated with a bridge (), for pivotally mounting the wheel set () relative to the bridge () about an axis (D). The first guide surface () is a single surface, located on a median plane (P) of said wheel set (), orthogonal to this axis (D), for holding the wheel set () careened or in a cantilever arrangement relative to this bridge (), and the wheel set () is free of any guide arbours on either side of this guide surface ().This wheel set () forms a ball bearing () wherein the first guide surface () forms an internal raceway () for balls () and wherein an external ball race () mounted on the bridge () includes the second guide surface () forming an external raceway for the balls ().

Timepiece wheel set with peripheral guiding

A change of state indicator () device for a timepiece display mechanism () by jumps of a given magnitude for the display of a transition between two stable display states of this given magnitude movable close to the display zone of this magnitude facing a supplementary display () driven discontinuously by a drive element () against elastic return means (). A driving pinion () controls a star wheel () in a discontinuous manner to control each jump against a beak () of a first arm () of a lever () controlling a pivoting movement and a return to position of this indicator () each time this beak () passes between two successive tooth spaces () of this star wheel () by means of a tooth () between these spaces (). The lever () includes a second support arm () for supporting the indicator () or controlling its displacement.

Change of state indicator for a jump display mechanism

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.

Universal watch

The invention concerns an oscillating weight () for an automatic winding watch, including a power reserve indicator device () integrated in said oscillating weight () and including means () for displaying the power reserve by comparison to complementary display means (), said display means () and complementary display means () being integrated in said oscillating weight (). Said display means () and complementary display means () are movably mounted to rotate synchronously, at a given moment, relative to said oscillating weight (). The invention also concerns an automatic winding watch including an oscillating weight () of this type, whose movements are transmitted to a mainspring of said watch.
