A watch device, more particularly an external watch device comprising two components () linked to one another, the first component () comprising a first guiding element () and the second component () comprising a second guiding element (), the two components being linked to one another in a movable manner by the cooperation of their respective guiding elements (), wherein the first guiding element () comprises a guiding surface in contact at least partially with the second guiding element (), said guiding surface comprising a polymer material belonging to the family of polyaryl ether ketones (PAEK).

Watch device having movable components

A process for manufacturing a timepiece component having a first step (E) consisting in arranging a metal insert in an injection mold, one surface of said metal insert being at least partially coated with a primer, a second step (E) of injecting an elastomer material into the injection mold in order to overmold the elastomer material over the metal insert, a third step (E) of vulcanizing the elastomer material, wherein the temperature of the injection mold is variable, and a step (E) of increasing the temperature of the injection mold between a first temperature at a first instant during the injection second step (E), and a second temperature higher than the first temperature at a second instant, during the vulcanization third step (E).

Process for manufacturing an elastomer timepiece component

A timepiece component, having a first part and a removable cap, which is able to adopt a fastening configuration in which the removable cap is fastened to the first part, and a free configuration in which the cap is separated from the first part. The first part comprises at least two latching members intended to cooperate with at least two corresponding assembly members of the cap in the fastening configuration. The cap or the first part is elastically deformable from a rest position to a deformed position which allows for positioning and removing for passing from the fastening configuration to the free configuration of the timepiece component and vice versa. The rest position allows stably maintain the fastening configuration of the timepiece component in which the at least two assembly members of the cap are in engagement with the at least two latching members of the first part.

Timepiece component provided with a cap

The invention relates to a bracelet lengthening device, comprising at least one adjusting assembly () that is movable relative to a clasp cover (), the adjusting assembly () and the cover () being provided with a first and a second fastening element ('), respectively, for fastening them respectively in several positions that are able to bring about different bracelet lengths, characterized in that the adjusting assembly () and the cover () are also provided with a first and a second indexing element (), respectively.

Device for adjusting the length of a bracelet

The system () for fixing a timepiece movement () to a watch case () element () comprises at least one clamp (), in particular at least two clamps, preferably three clamps or four clamps, which is intended to come into contact firstly with the movement and secondly with the watch case element, the at least one clamp being made of a superelastic alloy and/or of a shape memory alloy, particularly of a nickel-titanium alloy such as Nitinol.

System for fixing a timepiece movement in a watch case

The invention relates to a watchstrap () including a plurality of mutually hinged elements () which each comprise at least one link (') and at least one recess consisting of at least one hole (&#x2032;) for receiving therein a linking member (). Next to the open ends () of at least some of said holes (&#x2032;), a clearance () of the linking member () is provided, preventing any contact at said point between the latter and said links (&#x2032;).

Watchstrap made of hinged links

A bracelet strand () for a wristwatch has a first end () suitable for a connection to a watchcase (). A comfort pad () is arranged on the inner surface of the bracelet strand () towards this first end (). This comfort pad () has a longitudinal opening ().
