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.

The invention relates to a wristwatch with a clock generator assembly. The clock generator assembly comprises a first clock generator, a pulse counter, and an output device. The first clock generator comprises a piezoelectric oscillating crystal and is configured to generate a clock signal. The pulse counter is configured to count the clock signal of the first clock generator, wherein the output device is configured to output a useful signal if a count value of the counted clock signal of the first clock generator is equal to a predetermined count value.

A sympathique watch (10) including a horological movement including a going train (20), a display train (30) connected to at least one display of a time value, a sympathique hand-setting mechanism and a crown (13) operated hand-setting mechanism.
