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.

Method for creating a component

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.

A change of state indicator () device for a timepiece display mechanism () 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 () driven discontinuously by a drive element () against elastic return means (). A driving pinion () controls a star wheel () in a discontinuous manner to control each jump against a beak () of a first arm () of a lever () controlling a pivoting movement and a return to position of this indicator () each time this beak () passes between two successive tooth spaces () of this star wheel () by means of a tooth () between these spaces (). The lever () includes a second support arm () for supporting the indicator () or controlling its displacement.
