  • Patent number: 4470707
    Abstract: An electronic analog timepiece is disclosed that utilizes digital storage devices for setting alarm time and when selectively displaying, in response to the activation of a setting member, either alarm time or actual, updated time by the timepiece hands. When setting the alarm time, the minute hand and second hand are positioned on the timepiece display to indicate alarm time in hours and minutes, respectively. Specifically, the minute and second representations of the minute hand and second hand positions on the display are transformed, in a selected storage device, to alarm time hour and minute representations, respectively. When displaying either alarm time or actual, updated time from the other time presently being displayed, the setting member is activated to produce fast rotation of the hands from one time setting to the other.

  • Patent number: 4445785
    Abstract: An electronic analog timepiece with time zone and time setting modes selected by appropriate rotation and axial movement of a crown that controls a high speed stepping motor is disclosed. The stepping motor provides high frequency signals to produce time correction rotation of the timepiece hands. The speed of the stepping motor is reduced by a deceleration ramp from high speed prior to stopping the motor at the end of time correction. The time setting mode may be selected when the watch is in the shutdown mode and the time zone mode is selected when the watch is in the normal clockwise running mode by rotating the crown in either the clockwise or counterclockwise direction. The shutdown mode may be selected from the normal running mode by pulling the crown to its out/setting position and the normal running mode may be selected from the shutdown mode by pushing the crown to its on/run position.
