Abstract
The present invention concerns a wristwatch type of watch. More specifically, the watch comprises a display ( ), an electronic circuit ( ) controlling the display, a time set stem ( ), and at least two electrical contact elements ( ″). The time set stem ( ) can be placed in different axial positions and the stem comprises a crown ( ) accessible from outside the watch and a helicoidal zone ( ) which may have three helicoidal elements ( ″). When the time set stem is placed in a position such that the contact elements ( ″) are facing the helicoidal zone ( ), rotating the time set stem causes an electrical connection on the electronic circuit ( ) to alternately open and close. This generates at least two electrical impulse signals which are transmitted to the electronic control circuit. These signals are used to regulate different watch functions, such as time correction or controlling the time belt or the date.
