Alarm electric watch
First Claim
1. An alarm electric watch having an electro-optical display for the time and an alarm mechanism, said watch having a selecting device for the time at which the alarm is released, said time-selecting device comprising a manually displaceable element movable carried by a support element of said watch, one of said elements having an electrically conducting zone, a plurality of electrically conducting members associated with the electronic circuit of the watch carried by the other of said elements such that upon movement of said displaceable element a different combination of said conducting members makes contact with said conducting zone at each position of said displaceable element, each of said combinations of conducting members determining the time at which said alarm is released.

Abstract
An electric alarm watch with an electro-optical display and an alarm mechanism which is released by a time-selecting device including a manually displaceable time-selector mounted for movement to different positions corresponding to the time of day for selecting the time at which the alarm goes off. At each position of the time-selector a particular set or combination of electrically conducting members is engaged by an electrically conducting zone or brush for producing an electronic signal which is peculiar to that particular position of the time-selector. A decoder may be used for receiving this signal and supplying it in decoded form to a comparator which compares the information from the time-selector with that received from the time-display portion of the watch. The alarm goes off when the information from the watch circuit is in concordance with that received from the time-selector.
