  • Patent number: 4232510
    Abstract: Timepiece comprising means for attaining the function of measuring the time, a time display means, at least part of which is mechanically formed, a means for changing the displayed content of the time display means in response to the operation of an external actuating member and a means for setting information for setting the condition of a timepiece function in accordance with the operation of the external actuating member, the time display means serving as the display of the information to be set upon the setting of the information whereby there may be easily effected the setting of functions except the time setting without increase of the complication of the display means.
    Type: Grant

  • Patent number: 4209970
    Abstract: An electronic timepiece in which a higher frequency signal from a frequency standard is divided down to a lower frequency drive signal by a frequency converter. The drive signal is applied through a driver circuit to an electro-mechanical transducer which actuates time-representing members to indicate time. A control means is coupled to intermediate stages of the frequency converter and produces higher frequency drive signals. At least one contact plate made of flexible, electrically conductive material is adapted to be depressed from outside the watch case through a recess formed therein whereby the control means is connected to the driver circuit to apply the higher frequency drive signals to the electro-mechanical transducer thereby rapidly advancing the time-representing members.

  • Patent number: 4026100
    Abstract: A timepiece with a calendar mechanism for automatically correcting the date-indication at each end of the months with thirty days or less, which comprises first driving means for feeding a date dial, second driving means for selectively driving the date dial and means for controlling the second driving means to energized it at the end of the month with thirty days or less. The second driving means is supplied with a power blanched from the power transmitting route for the first driving means thereby resulting in the simplification in its construction.
