Abstract
Abstract The invention relates to a time setting device for an electronic watch comprising an oscillator, a frequency divider and counting and display devices for the minutes and for the hours connected in series. This device comprises further at least one commutator to switch the input of the counter of the watch onto a capacitor, a resistor charging said capacitor, the forward or backward stepping of this counter of one unit being controlled by the discharge of said capacitor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
71 words
A time setting device for an electronic watch comprising an oscillator, a frequency divider and counting and display devices for the minutes and for the hours connected in series and which comprises further at least one commutator to switch the input of the counter of the watch onto a capacitor, a resistor charging said capacitor, the stepping of this counter of one unit being controlled by the discharge of said capacitor.
Claim 2
Dependent Claim
71 words
A time setting device for an electronic watch comprising an oscillator, a frequency divider and counting and display devices for the minutes and for the hours connected in series and which comprises further at least one commutator to switch the input of the counter of the watch onto a capacitor, a resistor charging said capacitor, the stepping of this counter of one unit being controlled by the discharge of said capacitor.
Claim 3
Dependent Claim
27 words
A device according to claim 1 which comprises two commutators, the one for the setting of the minutes and the other for the setting of the hours.
Claim 4
Dependent Claim
70 words
A device according to claim 2, wherein said commutators, each associated with one of the counters of the watch, cause by the discharge of a capacitor, the forward stepping of one unit of the considered counter; and which comprises further two other commutators, each associated with one of the counters of the watch, causing by the discharge of a capacitor, the backward stepping of one unit of the considered counter.
Claim 5
Dependent Claim
14 words
A device according to claim 1, wherein the stepping of said counter is forward.
Claim 6
Dependent Claim
14 words
A device according to claim 1, wherein the stepping of said counter is backward.
