Abstract: A gear train structure of an electronic watch which is high in hand indication accuracy and which eliminates the occurrence of stopping of the watch due to dust, nap or the like. The electronic watch gear train structure includes a second wheel 13 having a minute hand attached thereto, and a braking wheel 15 for applying to the second wheel 13 a rotary torque of a reverse direction to a direction of rotation of the second wheel 13. The braking Wheel 15 includes a gear adapted to mesh with the second wheel 13, a spring 21 having one end thereof fastened to a shaft of the gear, and a balance spring frame 23 having a circumferential wall surface for contacting with the free end side of the spring 21.

Abstract: An electronic timekeeping apparatus includes a temperature value generating circuit for generating a temperature value, a temperature value converting circuit including a slope adjusting circuit which provides a slope corrected output in accordance with a frequency versus temperature characteristic of the apparatus in response to the temperature value, a pace compensation data circuit for producing pace compensation data corresponding to the slope corrected output, and a pace compensating circuit for compensating pace of the apparatus in accordance with the pace compensation data. An offset adjustment circuit may operate on said temperature value or said slope corrected output.
