The base element () includes first () and second () openings joined to the first () and second () spars so that they constitute the flexible member, a pressure exerted simultaneously on each of the spars () in a direction transverse to the clasp leading to an elastic deformation of the spars () and to the unbolting of the at least one cover () of the base element () to allow the wearer to open the clasp.

Bracelet clasp

A bracelet clasp () including a strip (), a first end () whereof is hinged to a first end () of a first bracelet strand (), and the second end () of the strip () is free, said strip () having a cut-out () forming at least a rigid portion () and two opposing deformable portions (), each including a hook (') arranged to engage with a hole () in a second bracelet strand () and to lock the clasp on said second strand (), simultaneous pressures exerted on the deformable portions () resulting in the unlocking of the clasp.

The invention relates to a method for broadcasting a message to a wearer of a watch comprising a step of digitising, by way of an electronic device, a graphical representation displayed in an aperture of a dial of said watch and a step of transmitting, by way of said electronic device, the message associated with said digitised graphical representation.

A horological movement () including: a plate (); a mechanical resonator () including an oscillating balance () rotatably mounted relative to the plate (), and a spiral spring () coupled to the balance (); an electromagnetic regulator () coupled to the mechanical resonator () to regulate the frequency of the oscillations of the balance (), and including at least one permanent magnet () fixedly mounted relative to the plate (), at least one coil (), a quartz or silicon resonator () and an electronic circuit () connected to the resonator () and to the coil (), all mounted on the balance () while being completely included in an inner cavity () delimited by the latter.

Self-adjustable horological oscillator

A transponder for securing a product displayed in a shop. The transponder includes two blocks each including a contact surface, the contact surfaces being positioned face to face, the blocks being connected to each other by an adjustable connection, that allows to manually adjust the moving closer together or farther apart of the blocks with respect to one another, thus allowing the transponder to be attached to a suitable element of the product, by gripping the element between the contact surfaces of the blocks, one of the blocks including wireless detection and transmission equipment, which allows the remote management of the presence of the transponder on the suitable element.

Anti-theft transponder

A device for autonomous adjustment of the active length of a balance spring includes a regulator mounted on a plate with a cock, a balance spring stud holder being pivotally mounted on the cock, the regulator being pivotally mounted on the stud holder and including a pivot arm and device for changing the active length of the balance spring by pivoting the regulator. The device includes an elastic stress device to exert an elastic, return-to-position action on the regulator, and an inertia block, mounted for free rotation on the cock and connected to the pivot arm of the regulator, arranged to move the pivot arm of the regulator between a rest position and a correction position of the device, and simultaneously act on the device for changing the active length of the balance spring.

The invention relates to a timepiece comprising at least an hour indicator, a minute indicator, a movement arranged to drive the hour indicator and the minute indicator, a dial, a crown and an indicator for at least one time zone, housed inside a first case. According to the invention, the first case is rotatable inside a second case about an axis of rotation, so that a rotation of the first case in a clockwise or anticlockwise direction with respect to the second case allows a time zone to be chosen and the time in the selected time zone to be indicated.

Time zone indicator device

A timepiece movement is provided, including a first regulating member and a first escapement associated therewith; a first train connecting the first escapement to a first energy source; a second regulating member and a second escapement associated therewith; a second train connecting the second escapement to a second energy source; a display of a current time; at least one differential gear including a first input wheel meshing with the first train and a second input wheel meshing with the second train, the at least one differential gear driving the display, where the second regulating member consumes less energy than the first regulating member.

Movement with power reserve extension

A timepiece movement is provided, including a first regulating member and a first escapement connected by a first train to a first energy source, where the first train, the first escapement, the first regulating member, and the first energy source together define a first assembly; a second regulating member and a second escapement connected by a second train to a second energy source, where the second train, the second escapement, the second regulating member, and the second energy source together define a second assembly; at least one differential gear configured to ensure a kinematic connection between the first and the second assemblies; a display of the current time; and a mechanism for stopping and allowing operation of one of the regulating members, where the differential gear carries the display to display the current time regardless of which of the regulating members is operating.

An adjustable link for bracelets, including a first half link and a second half link arranged to be assembled to move with respect to each other, including an adjustment, and a locking mechanism cooperating with a complementary locking mechanism in order to form a captive assembly. The adjustment includes a screw, a hole passing through the first half link, and a blind threaded hole extending into the second half link, the through hole and the blind threaded hole facing each other, and being arranged to cooperate with the screw to continuously adjust the position of the first half link and of the second half link in the longitudinal direction in order to adjust the position between a maximum position and a minimum position.

Adjustable link for bracelets

The invention relates to a timepiece movement comprising at least first and second functions implementing the display of at least first and second pieces of information. According to the invention, the movement has a selection member comprising an actuator, at least one lever configured to take at least first and second positions, respectively corresponding to the first and second functions, and respectively corresponding to the creation of first and second kinematic connections, and a cam cooperating with the actuator and the at least one lever so as to create the first and second kinematic connections.

Chronometer with speed selector

Multi-sector mechanism () for displaying a physical quantity on a timepiece (), on several partial displays (), each representing the change in said physical quantity over a given partial range (), the total range of variation in said quantity being covered by the set of said partial ranges (), each partial display () including an indicator () that moves relative to a scale () representing the partial range () specific thereto. Each partial display () includes a continuous mechanism () for moving the moving indicator () thereof opposite a scale representing said total range, and includes eclipsing means arranged for only allowing said moving indicator () to be seen opposite said scale () representing the partial range () specific thereto, and for reducing or obscuring visibility of said moving indicator () opposite the scales representing any other partial ranges, and said continuous mechanisms () of said partial displays () are all synchronous with each other.
