Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
121 words
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.
Claim 2
Dependent Claim
121 words
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.
Claim 3
Dependent Claim
79 words
An alarm electric watch as defined in claim 1, which further comprises a decoder for receiving information supplied by said selecting device, a comparator connected to said decoder for receiving information as to the position of said time-setting device, said electro-optical display having a feed circuit to which said comparator is also connected for receiving information as to the time kept by watch, whereby any concordance between the two types of information received by said comparator activates said alarm.
Claim 4
Dependent Claim
58 words
An alarm electric watch as defined in claim 1, wherein said conducting zone comprises a brush and said conducting members are interposed between isolating members and are arranged such that upon movement of said displaceable element the combination of conducting members in contact with said brush is varied from one position of said displaceable element to the next.
Claim 5
Dependent Claim
17 words
An alarm electric watch as defined in claim 3, wherein said displaceable element comprises a rotatable bezel.
Claim 6
Dependent Claim
53 words
An alarm electric watch as defined in claim 1, which further comprises a decoder for receiving information supplied by said selecting device and a manually operable switching device capable of connecting said decoder to said electro-optical display for displaying the time selected for release of the alarm instead of the time of day.
