A pressure-relief valve () including: a tube () intended to be fastened to a watch case, a recessed head () mounted movable in rotation and in translation about and along the axis of the tube (), the head () being able to adopt a first axial position where a gas flow could be performed between the inside and the outside of the watch case and a second axial position where this gas flow is prevented, a first insert () mounted within the recess of the head (), the valve () being wherein the head () is mounted on the tube () via the first insert () and wherein the head () is fastened to said first insert () by a screw thread and/or a glue.

Pressure-relief valve for a watch

A control device of a horological movement including a first part comprising a sliding guide tube and an activation module, and a second part slidably guided by the sliding guide tube in an axial direction relative to said first part, between an active position and an inactive position, wherein said second part comprises a slider fixed to the adjustment rod and cooperating with the activation module, and wherein the activation module includes a sheath fixed to the guide tube, cooperating with the slider and a sleeve kinematically connected with the sheath in a helical connection and being configured, under the action of an elastic member to apply mechanical stresses to the slider when the second part moves between the active position and inactive position.

Device for controlling a horological movement with tactile feedback and timepiece, in particular a watch, comprising such a device

A push button system for activating an actuation member, the system including a button head, a pusher actuator integral with the button head, a first hollow guide member, the pusher actuator being mounted to slide inside the first hollow guide member, the first hollow guide member being intended to be secured to a fixed element relative to the button head and to the pusher actuator, a second hollow guide member arranged in the button head, and a pin mounted to slide inside the second hollow member, and intended to be secured to the fixed element. The pusher actuator has an upper portion provided on the periphery thereof with a collar intended to cooperate with an internal face of the first hollow guide member to guide the pusher inside the member.

Push button system and timepiece comprising the same

A sealing device () for a watch () configured to be inserted into a primary space () comprised in a middle part (). The sealing device () includes an insertion organ () configured to be inserted into the primary space (), a first sealing elements set () configured to seal the primary space () between the middle part () and the insertion organ (), and a sealing elements set () configured to seal a secondary space () between a drive organ () and the insertion organ ().

Sealing device

An external watch control device () including a crown () carrying a first barrel () screwed onto a tube (), coaxially guiding a second barrel () includes a driver (), the first barrel () and the second barrel () including opposing unidirectional toothing (), the tube () containing a spring () tending to move the first barrel () away from the driver (), the unidirectional toothing () are at maximum distance when the crown () is completely screwed onto the tube (), and in meshing position when the crown () is completely unscrewed, the cooperation between the unidirectional toothing () allowing the rotation of the first barrel () in a first single direction of rotation of the crown (), and preventing it in the opposite direction against the spring () in the manner of a pawl.

External control mechanism for a timepiece

A control device () for a horological movement, including a first part including a sliding guide tube () intended to be fixed relative to the horological movement, and a second movable part () slidably guided by the guide tube in an axial direction, relative to the first part, between an active position wherein it is able to be integral, by means of an adjustment rod (), with a component of the horological movement, and an inactive position wherein the adjustment rod is intended to release the component of the horological movement. The second part includes a head () covering a reversible elastic casing module () fixed to the adjustment rod and arranged so as to occupy a rest state when the second part occupies the active and inactive positions and being urged by the guide tube when the second part moves between these positions.

A timepiece incudes a crown () housed in a cavity () provided in the case and open towards the outside, such as a cavity () in the side wall of the case () of a wristwatch, in the rest position of the crown (). To bring the crown out of its rest position, the user rotates a rotary knurling-roller (). The knurling-roller () is coupled to a tube () wherein is inserted a crown body () integral with the crown. The rotation of the knurling-roller actuates rotation as well as translation of the tube, which is linked only in translation to said cylinder (). The tube displaces the crown in an axial direction without rotating the crown around its central axis (). At least one control position of the crown and the rod can be reached, by rotating the knurling-roller () without having to manually pull the crown outwards.

Device for controlling a timepiece

A stem-crown of a water-resistant watch case includes a stem inserted into a tubular opening of a middle part of the watch case, and a crown including a first portion connected to the stem and a second handling portion. The first portion of the crown includes an annular contact surface, which is inclined at a determined angle less than 90&#xb0; relative to a longitudinal central axis of the stem-crown, extending from the link between the stem and the first portion of the crown towards the outside of the second portion of the crown. In a rest position, the first portion of the crown comes into contact or bears against an annular receiving surface of the middle part, the shape thereof complements that of an end of the tubular opening to the outside.
