An electronic watch including a case provided with a middle and with a bezel entirely or partially forming a tactile interface, the case including an electronic device including an electronic circuit provided with a substrate wherein a peripheral area of its upper surface forms with the bezel mounted over the middle a hatch within which are included an antenna circuit of a communication module and a tactile control circuit of a tactile control member of the electronic device, the tactile control circuit including at least one cambered element made of a conductive material forming an electrode one end of which is connected to a connection terminal of the tactile control member which is comprised over the peripheral area of the upper surface of the substrate.

Electronic watch

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 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.

Watch configured to perform contactless electronic transactions

A method and device for determining a constant parameter of an inhibition value for adjusting the device operating frequency of a watch equipped with a quartz oscillator. The following steps are performed by a self-calibration circuit of the electronic watch device: from a first external pulse and a second external pulse received from a system external to the watch and separated by a measurement time, corresponding to a reference number of reference periods for a periodic calibration signal derived from the time-measurement signal and having a calibration frequency derived from the natural frequency of the quartz oscillator, determining a calibration parameter representative of a ratio between a calibration period and a reference period for the periodic calibration signal, and determining a constant inhibition parameter as a function of the calibration parameter.
