摘要： Second adjustment system in an electronic watch employing a quartz oscillator as a time base. The watch comprises a standard oscillating circuit including the quartz oscillator, a divider, a driving circuit, and a converter. The divider produces several oscillatory output signals of different frequency so as to produce diverse time signals. A time signal selection switch selects output among these outputs. The selected output time signal corresponds to the signal required for adjusting a time delay or a time advance of the seconds indicated by the watch. An incorrect time is corrected during normal watch operation by this second adjustment system.

摘要： A system for driving a bipolar stepping motor by a pair of pulse driving currents wherein an output level of a control circuit is selected depending on one of the pulse drive currents applied just prior to the stoppage of the motor by a reset signal, switching of a set of signal transmitting paths for connecting between a reference signal generating circuit and a motor drive circuit is selected depending on an output level of the control circuit, that one of a pair of reference signals produced by the reference signal generating circuit during the operation of the motor which first appears after the release of the stop causes production of the other of the pulse drive currents by the selected path, and a predetermined time period after the release of the stop the pulse drive current of opposite polarity to that of the pulse drive current being applied to the motor which is just about to stop is applied to the motor to positively re-start the operation of the motor at a predetermined time.

摘要： An electronic timepiece can prevent overrunning when driving a motor at a high speed. The electronic timepiece has a controller that controls a driver to an on state or an off state according to the current value detected by the current detector; a polarity changer that determines driving one step of the motor ended and changes the polarity of the drive current when the on time or off time is detected to meet a specific condition; and a drive period adjuster that sets the terminal supplying the drive current to the coil to a first state if the remaining drive step count is greater than the remaining count evaluation number, and if the remaining drive step count is less than or equal to the remaining count evaluation number, sets the terminal to a second state in which the brake force applied to the rotor is greater than in the first state.

摘要： An electronic timepiece that drives a function indicator and a calendar wheel with a single motor, and can return the function indicator to the reference position when the position of the function indicator shifts due to an external disturbance. The electronic timepiece has a function indicator for displaying information other than time; a driver that drives the function indicator; a display member that is driven in conjunction with the function indicator to display information based on time; an indicator position detector configured to detect the function indicator at an indicator position detection position; and a controller that controls the driver and the indicator position detector to execute a function indicator position detection process.

摘要： A hand position identification device includes a rotation detection unit that detects a rotation state of a rotor by using an induced voltage generated in a motor for rotating a hand, a storage unit that stores a timing information piece relating to a timing at which the induced voltage exceeds a predetermined threshold, and a control unit that compares a first timing information piece stored in the storage unit and obtained in a case where the hand is located at a first position, with a second timing information piece obtained in a case where the hand is located at a second position, and that identifies the second position as an identified position in a case where a difference between the first timing information piece and the second timing information piece is equal to or more than a predetermined amount.

摘要： The presentation case is arranged for receiving an electromechanical watch provided with a stepping motor for driving the watch hands. The presentation case includes a box with a support for receiving the watch, a system for detecting the position of the hands, means for resetting the watch, connected to the hand position detection system, and configured to reset the watch on the basis of information received from the hand position detection system and a time reference, when the watch is placed on the receiving support. The resetting means include a drive means for the stepping motor of the electromechanical watch, which is arranged inside the presentation case facing the stepping motor, when the watch is placed on the receiving support, and is configured to cause a rotation of the stepping motor by inductive coupling.
