A method for fabricating a timepiece component made of conductive material includes: making a base from conductive material; coating the base with a first layer of sacrificial metal protection material; etching a recessed decoration mechanically or with a laser; coating the first recessed decoration and the remaining part of the first layer with a second metal and/or coloured decorative treatment layer; and removing each first sacrificial metal protection layer by chemical devices, to obtain a blank including a first decoration formed by the remaining part of the second layer.

The invention provides a wearable device, such as a watch, that provides a way to calculate an appropriate camera shutter speed and aperture setting for a given ISO speed setting to obtain settings that, when entered into a camera, will result in an appropriate photographic exposure. The devices of the invention provide a simple, fast, convenient way to calculate appropriate settings for the components of the photographic exposure triangle.

For example, an escape gear portion as a watch component includes a substrate containing silicon as a main component, and a light reflecting layer including a first silicon oxide layer, a silicon layer, and a second silicon oxide layer that are stacked, in this order, at the substrate, wherein, when the light reflecting layer is viewed in plan view, the light reflecting layer includes a first region and a second region, and a thickness of the silicon layer in the first region is different from a thickness of the silicon layer in the second region.

A method for fabrication of a composite component including a first material containing steel 316L and a second material containing zirconia powder formed in a single sintering.

The timepiece is equipped with a case which comprises a case middle, a pusher and a locking device for this pusher. The pusher is arranged movably in a translational manner in an actuation axis. The locking device contains a blocking means that is movable in a translational manner along the actuation axis and with the ability to be displaced between a locking position and an unlocking position, in which positions the pusher is respectively to the locking and unlocking positions blocked and free in translation. The locking device contains in addition a control means rotatably mounted in a general plane of the case between a first position and a second position corresponding respectively to the locking and unlocking positions for the blocking means, this control means containing means for driving the blocking means between its locking and unlocking positions.

The invention relates to a method for producing a watch glass, in which at least one diamond or jewel, or other gemstone is embedded, the method comprising the steps of providing a carrier glass, providing a cover glass, introducing at least one recess into the carrier glass, providing at least one diamond, jewel, or other gemstone, inserting the at least one diamond, jewel, or gemstone into the at least one recess of the carrier glass, placing the cover glass on the carrier glass, and connecting the cover glass to the carrier glass such that an airtight connection point between the cover glass and the carrier glass is formed, which is subject to a suction cup effect. The invention further relates to a watch glass that is produced according to the method of the invention. The invention further relates to a watch having a watch glass according to the invention.

A control system for a rotating element of a timepiece including a control element for actuating the rotating element and a transmission device between the control element and the rotating element. In the control system a gearing device includes a hybrid gearing device including a first element, which is movable around a first rotation axis and including a drive runner made from elastomeric material, and a second element, which is movable around a second rotation axis and including a rolling tooth system. The drive runner cooperates with the rolling tooth system by friction.
