Provided is a system for setting an electronic watch, the system includes a portable electronic appliance provided with a near-field communication device and a microcontroller configured to control said device. The watch includes a near-field communication module and a microcontroller configured to exchange electric signals with this module, said watch and said appliance being configured to be connected, in the near field, with one another in order to carry out the setting operation for the watch.

System for setting a watch

A fastening method is for fastening at least one display element of a watch using a fastening device. Indeed, the at least one display element is fastened thanks to the fastening method via the fastening device. For this, it is necessary to provide the at least one display element, at least one movement, and at least one split ring, then to deform the at least one split ring so as to adapt to the at least one display element before fastening the at least one split ring with the at least one display element to the at least one movement.

Motor group for watches

A method for setting an electronic watch including a near-field communication module and a microcontroller configured to exchange electric signals with this module, the method including: establishing a near-field connection between the electronic appliance and the watch; verifying, by way of the microcontroller of the electronic appliance, the accuracy of a datum indicating the clock state of the watch; sending, to the near-field communication module of the watch, by way of the near-field communication device and when instructed to do so by the microcontroller of the electronic appliance, at least one watch setting instruction when the clock state datum is inaccurate; processing said at least one instruction received by means of the microcontroller of the watch, in order to generate watch setting parameters; and configuring the watch when instructed to do so by the microcontroller of the watch, according to the setting parameters generated.

Method for setting an electronic watch

A display mechanism for a watch and a watch including the display mechanism, which includes a display for displaying information, a first and second mobile elements and a support, so that when the first mobile element moves with a first primary speed, the second mobile element moves into a first position so as to cover the display and when the first mobile element moves with a first secondary speed, the second mobile element moves into a second position so as to expose the display. Thus, the display can be exposed which allows to maximize the display surface when information is present on the display.

Display mechanism for a watch

A watch is includes a case including at least one pair of horns, a horological movement, and a near field communication module configured to perform contactless electronic transactions. The near field communication module may be connected to the horological movement by being arranged between horns of the at least one pair of horns.
