Abstract: A method for manufacturing a component in a substrate including: a) modifying a structure of at least one region of the substrate to make the at least one region more selective; and b) chemically etching the at least one region to selectively manufacture the component.

Abstract: A two-directional date corrector mechanism controlled by a pull-out piece for a date mechanism. The mechanism includes a 24 hour wheel, a date updating finger pivoting integrally therewith, a date driving star-wheel, and a corrector star-wheel meshing therewith and located between the date driving star-wheel and the finger and configured to be uncouplable from the finger under action of an uncoupling mechanism controlled by the pull-out piece, the uncoupling mechanism having a coupling position where the corrector star-wheel meshes with the finger, and an uncoupling position where it is released from the finger to allow the date to be corrected. A date mechanism can include such a date corrector mechanism and a timepiece can include such a date corrector mechanism.

Abstract: A change of state indicator (2) device for a timepiece display mechanism (30) by jumps of a given magnitude for the display of a transition between two stable display states of this given magnitude movable close to the display zone of this magnitude facing a supplementary display (3) driven discontinuously by a drive element (7) against elastic return means (19). A driving pinion (9) controls a star wheel (10) in a discontinuous manner to control each jump against a beak (14) of a first arm (15) of a lever (13) controlling a pivoting movement and a return to position of this indicator (2) each time this beak (14) passes between two successive tooth spaces (12) of this star wheel (10) by means of a tooth (11) between these spaces (12). The lever (13) includes a second support arm (16) for supporting the indicator (2) or controlling its displacement.

Abstract: The timepiece movement includes a barrel, an escapement that has an escape wheel and pinion (27, 25), a balance (19) and a gear train for transmitting energy stored in the barrel to the escape wheel. This gear train has an intermediary wheel (23), kinematically connected to the barrel by a first part of the gear train, and kinematically connected to the escape wheel (27) by a second part of the gear train, the second part of the gear train, and the escapement and balance are mounted in a rotating carriage (16) kinematically connected to the movement and arranged for rotating coaxially about the intermediary wheel (23) at a different speed from the speed of the intermediary wheel. The timepiece movement is characterized in that it imposes a speed of one revolution per minute on the carriage (16).

Abstract: The invention concerns an oscillating weight (1) for an automatic winding watch, including a power reserve indicator device (100) integrated in said oscillating weight (1) and including means (20) for displaying the power reserve by comparison to complementary display means (30), said display means (20) and complementary display means (30) being integrated in said oscillating weight (1). Said display means (20) and complementary display means (30) are movably mounted to rotate synchronously, at a given moment, relative to said oscillating weight (1). The invention also concerns an automatic winding watch including an oscillating weight (1) of this type, whose movements are transmitted to a mainspring of said watch.
