Abstract
Abstract In an electronic time piece of the type wherein oscillator pulses are passed into a frequency divider and the output of the frequency divider is passed through switching means to pulse a motor which drives the display mechanism, a manual control is provided external to the watch case. The manual control has a neutral position, a first active position whereat it enables mechanical correction of the hour hand, and a second active position whereat it operates the switching means to bypass a portion of the frequency divider thereby increasing the rate at which the motor is pulsed and the minutes hand is advanced.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
142 words
An electronic time piece of the type comprising a high frequency oscillator, a frequency divider circuit and switching means coupled to said divider circuit for controlling a motor, said motor driving a display mechanism which includes at least a minute hand and an hour hand, and wherein a single control mechanism accessible from the exterior is arranged to occupy three positions, the intermediate of which is a neutral position, the position of the mechanism when drawn to the exterior relative to the neutral position enabling a mechanical correction of the hour hand and a pushed-in position relative to the neutral position changing the state of the switching means to by-pass a predetermined number of stages in said frequency divider circuit, thus modifying the energy supply to the motor in a manner to increase its speed of rotation for the minute hand setting.
Claim 2
Dependent Claim
142 words
An electronic time piece of the type comprising a high frequency oscillator, a frequency divider circuit and switching means coupled to said divider circuit for controlling a motor, said motor driving a display mechanism which includes at least a minute hand and an hour hand, and wherein a single control mechanism accessible from the exterior is arranged to occupy three positions, the intermediate of which is a neutral position, the position of the mechanism when drawn to the exterior relative to the neutral position enabling a mechanical correction of the hour hand and a pushed-in position relative to the neutral position changing the state of the switching means to by-pass a predetermined number of stages in said frequency divider circuit, thus modifying the energy supply to the motor in a manner to increase its speed of rotation for the minute hand setting.
Claim 3
Dependent Claim
24 words
An electronic time piece as in claim 1 wherein the control mechanism is in the form of a stem-push piece provided with a crown.
Claim 4
Dependent Claim
47 words
An electronic time piece as in claim 1 wherein the change of state of the switch removes from the frequency dividing circuit a predetermined number of stages whereby the motor is energized at a frequency substantially higher than that applied during normal running of the time piece.
Claim 5
Dependent Claim
21 words
An electronic time piece as in claim 2 wherein the hour hand correction is effected through manual rotation of the crown.
Claim 6
Dependent Claim
25 words
An electronic time piece as claimed in claim 3 wherein the control mechanism is in the form of a stem-push piece provided with a crown.
Claim 7
Dependent Claim
22 words
An electronic time piece as claimed in claim 3 wherein the hour hand correction is effected through manual rotation of the crown.
Claim 8
Dependent Claim
16 words
An electronic time piece as claimed in claim 1 wherein said motor is a stepping motor.
Claim 9
Dependent Claim
16 words
An electronic time piece as claimed in claim 1 wherein said motor is a synchronous motor.
