Wristwatch
First Claim
1. A watch comprising:
- a display (11);
an electronic circuit (12) controlling operation of the display (11), and the electronic circuit having electrical contacts;
a time set stem (13); and
at least two electrical contact elements (14, 14″
) controlled by the time set stem (13), each of the at least two electrical contact elements (14, 14″
) alternately opening and closing an electrical connection with one of the electrical contacts of the electronic circuit (12), when the time set stem (13) is rotated, to generate electrical impulse signals transmitted to the electronic circuit (12) for controlling operation of the display (11);
wherein the time set stem (13) has at least one helicoidal element (20, 20′
, 20″
, 24, 24′
) which extends along a helicoidal zone (19) of the time set stem (13), and when the time set stern (13) is sufficiently extending from the watch, the at least one helicoidal element (20, 20′
, 20″
, 24, 24′
) cooperates with the at least two electrical contact elements (14, 14″
) to move alternately the at least two electrical contact elements (14, 14″
) in and out of contact with the electrical contacts of the electronic circuit (12), for opening and closing the electrical connection of the electronic circuit (12), upon rotation of the time set stem (13).

Abstract
The present invention concerns a wristwatch type of watch. More specifically, the watch comprises a display (11), an electronic circuit (12) controlling the display, a time set stem (13), and at least two electrical contact elements (14, 14″). The time set stem (13) can be placed in different axial positions and the stem comprises a crown (16) accessible from outside the watch and a helicoidal zone (19) which may have three helicoidal elements (20, 20′, 20″). When the time set stem is placed in a position such that the contact elements (14, 14″) are facing the helicoidal zone (19), rotating the time set stem causes an electrical connection on the electronic circuit (12) 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.
