摘要： Provided is a timepiece that improves the ease of unwinding a spring. The timepiece has a bridge disposed between the rotor and the main plate when seen in a side view; a pawl lever that is disposed between the rotor and bridge in side view, moves bidirectionally in a direction toward and a direction away from the transmission wheel in conjunction with the rotor, and causes the transmission wheel to turn in one direction; a release mechanism that is disposed to the bridge, and can change between an engaged state in which the pawl lever and the transmission wheel are engaged, and a released state in which the pawl lever and the transmission wheel are not engaged; and a train bridge disposed in side view between the pawl lever and the rotor, and having a first hole disposed to a position superimposed with the release mechanism when seen in a plan view.

摘要： A pivot arbor for a timepiece movement includes a pivot made of a first non-magnetic metal material at at least one end in order to limit the sensitivity to magnetic fields. An outer surface of the pivot is coated with a first layer of a second material such as Ni, NiB, and/or NiP. The first layer of the second material is partially coated with a second layer of a third material selected from gold, silver, copper, platinum, rhodium, palladium and their alloys.

摘要： Timepiece wheel set with a unidirectional wheel rotating in only one direction in cooperation with a ratchet wheel, which is movable inside a ratchet wheel chamber, comprising a click that rotates integrally with this wheel, which forms a one-piece component comprising at least one spring-arm, at the end of which, on a first side, a beak cooperates directly with the toothing of a ratchet wheel in an operating position in which this spring-arm is free, and on a second side, a first hook can cooperate with a second hook of complementary shape, comprised in this one-piece click, in a rest position in which this spring-arm is in an extended position, the elasticity thereof allowing this first hook to be hooked or unhooked with respect to this second hook by the action of an operator, by maximum elongation of this spring-arm and/or by the tilting of this end.

摘要： A timepiece movement includes second, minute, and hour hand wheels with second, minute, and hour hand arbors; a 24-hour hand wheel with a 24-hour hand arbor; and a first to third guides that guide an arbor to which a hand attaches. The minute, hour, and 24-hour hand arbors have tubular configurations and are disposed coaxially to the second hand arbor. The minute hand arbor has a diameter greater than the second hand arbor, the hour hand arbor has a diameter greater than the minute hand arbor, and the 24-hour hand arbor has a diameter greater than the hour hand arbor. The first guide is between the second hand arbor and the minute hand arbor, the second guide is between the minute hand arbor and the hour hand arbor, and the third guide is between the hour hand arbor and the 24-hour hand arbor.

摘要： This invention teaches a new class of materials that can be used to manufacture hairsprings and/or other components of mechanical watches, and methods for manufacturing these components. The new class of materials is crystalline compounds, including, but not limited to, gallium arsenide, extrinsically doped gallium arsenide, extrinsically doped silicon, gallium nitride, extrinsically doped gallium nitride, gallium phosphide, extrinsically doped gallium phosphide, and quartz. This invention also teaches laminated/coated crystalline compounds. The lamination/coating may be applied by one of the following methods, including but not limited to: plasma enhanced chemical vapor deposition, atomic layer deposition, sputtering, electron beam evaporation, and thermal evaporation. Using crystalline compounds, in particular extrinsically doping the crystalline compounds, affords the possibility to controllably alter the mechanical, electrical, thermal, magnetic, and/or other properties of the watch components. These properties can be further altered by applying single or multiple laminates/coatings of varying thicknesses and/or geometries.

摘要： A timepiece barrel includes a drum defining a first compartment and a superimposed second compartment; a first tubular hub secured to a first cover and housed at least partially in the first compartment; a second tubular hub secured to a second cover housed at least partially in the second compartment. Each compartment contains a spring wound into a spiral and an inner first end of which collaborates with the first and second hubs respectively and a second end of which collaborates with the drum. The compartments are open on the side of the covers and the first and second covers are free with reference to the drum and are each provided with peripheral teeth, while the drum has no teeth.
