Indexing device () for a pull-out piece () for a timepiece,

Pull-out piece indexing device

A system () for displaying time or time derivative information, in particular a measured time, the system including a limb () comprising at least one modifiable graphic element (-) forming time or time derivative reference information, a member () for indicating the time or time derivative information in cooperation with the limb, a device () for modifying the graphic element, and a device () for resetting, by action of a user, to a predetermined configuration, in particular for resetting to zero, the time or time derivative information displayed by cooperation of the indication member and of the limb.

Horological display system

Rotating bezel blocking device

A transmission coupling (), especially a timepiece transmission coupling, for the mechanical linkage of at least one first part (A) of a first shaft at least movable in rotation about a first axis (A) to at least one second part (A) of a second shaft at least movable in rotation about a second axis (A), the first and second axes being parallel or substantially parallel, the transmission coupling including the at least one first part (A), the at least one second part (A), and at least a first elastic return system ('-) arranged so as to limit or cancel out the play between the at least one first part (A) and the at least one second part (A), and connecting the at least one first part (A) and the at least one second part (A).

Timepiece transmission coupling

A bracelet clasp including first and second movable leaves pivoted about a central blade, that can occupy a first closed position suitable for holding a bracelet around the wrist of its wearer and a second open position suitable for removing the bracelet from the hand of its wearer. The two movable leaves include at least one element for interaction between them which acts on the second movable leaf when the first movable leaf is actuated, in the closing and/or opening phase of the clasp.

Fold-over clasp for a bracelet

This timepiece has a case () enclosing a horological movement (), and a transmission mechanism for transmitting constant-velocity rotary movements between two stems () on parallel axes, connecting the outside of the case () to the horological movement () through a hole in the case (). The adjacent ends of the two stems () are connected to two respective sliding elements () having defined cross sections engaged with two respective slide-ways () having cross sections complementary to those of the sliding elements, having sliding planes perpendicular to said axes, the two slide-ways () being connected to a common linking member () and being oriented at an angle of 90&#xb0; to each other.
