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

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

Device for adjusting the length of a bracelet, having a guidance and fastening system (), including at least one adjusting link element () mounted with the ability to rotate about an axis of rotation (A) defined by a guidance device of the guidance and fastening system. The guidance and fastening system () includes an elastic fastening device comprising an elastic property in order to perform an elastic fastening function. The two guidance and elastic fastening devices are arranged around the axis (A), notably upon implementation of the fastening function. The elastic fastening device provides elastic immobilization of an end link element () connected to the adjusting link element (), particularly relative elastic immobilization of the said end link element () with respect to the adjusting link element (), or of the adjusting link element (), in at least one configuration of the adjustment device.

An assembly device () for pivotally attaching at least two parts (M, M), comprising a screw () designed to be screwed into a first piece (M) and carrying a pivoting guide pin () of a second part (M), wherein this assembly device () comprises at least one elastic ring () able to work in conjunction with an element blocking one of the two parts (M, M), so as to prevent accidental axial movement of the assembly device ().

Device and method for pivotal assembly of at least two parts, corresponding assembly of the two assembled parts

A clasp including long hinged arms (), a mechanism for adjusting the longitudinal position of the connecting member () connecting one of the free ends of the band to one of the long arms (), having two tracks () defining two corresponding paths extending in two planes parallel to the longitudinal axis of the arms (), and sliding elements () for engaging with the respective guide tracks (), the respective cross sections of the tracks and of the sliding elements including complementary adjacent surfaces to limit the movement of the sliding elements () to one degree of freedom corresponding to the sliding path of the tracks (), in such a way as to ensure free translational movement of the connecting member.
