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 watch corrector () including at least one case () and at least one mobile element (). In order to avoid a movement according to a degree of freedom, the at least one mobile element () is inserted by force, preferably, the at least one mobile element () includes at least one second immobilisation member () configured to immobilise the at least one mobile element () in the at least one case (), and the at least one case () is inserted by force, preferably, the at least one case () includes at least one first immobilisation member () being configured to immobilise the at least one case () in the watch middle ().

Watch corrector and watch middle

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

A crown-push-button () provided with a spring () disposed within a cage () integral in rotation with the movement of the head () of the crown-push-button (), the spring () being arranged within the cage () so as to be rotated with the cage. The base () of the spring cage is provided with cells () cooperating with protuberances () formed in a washer () disposed on the seat () of the tube () of the crown-push-button, the rotation of the crown-push-button being then accompanied by a click as the protuberances () pass in the cells (), which allows the user to ensure that the desired functions have been activated.

Crown-push-button for a timepiece

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 crown/pusher including a tube attached to a watch case, a recessed head integral with a stem which is movable with respect to the tube and defines an axis, the recessed head being mounted to move in rotation and in translation respectively around and along the axis of the stem, a return spring disposed around the stem, the crown/pusher includes a cage housing the spring, the cage being traversed by the stem and including an upper part integral with the recessed head and a lower part freely mounted with respect to the recessed head, the upper part cooperating with the lower part in order to drive the lower part in its rotational movement and in order to move in translation along the axis with respect to the lower part, the spring being compressed inside the cage in order to be driven in rotation with the cage.

Crown/pusher for timepieces

A method for manufacturing a decorative article () including the following steps of: making a blank by injection moulding a material comprising a metallic material, machining and/or polishing the blank to form a product, and forming the product to print a raised or recessed relief pattern () on part of the surface of the product, the product with the pattern () forming the decorative article. Also, a decorative article, notably an external timepiece part made of a sintered material having on part of its surface a raised or recessed relief pattern () made by a forming process. Preferably, the sintered material is a grade 5 titanium alloy (Ti6V4Al) or a stainless steel.

Method for manufacturing a decorative article

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.
