Special Features

  • Quartz Accuracy - Stabilized quartz crystal assures high accuracy to within ±15 seconds per month.
  • Reliability - A minimum number of parts (17 in entire motor) reduces wear within the motor and assures trouble-free operation. The motor is completely enclosed in its case, so dust and dirt cannot get into the motor.
  • Compact Size - The motor is approximately 2-1/8”x 2-1/8” x 1/2”.
  • Battery Life - The motor runs approximately two years on a fresh “AA” battery, not included.
  • Step Second Motion - The second hand, if used, moves in exact one second steps.
  • Select clock hands from hand page.

 

    These Seiko motors will operate a second hand, but second hands are considered optional. See the bottom of the motor page for the link to our selection of second hands. Seiko motors require a .034 - .035 diameter second hand bushing as shown below. This hole size is too large for many other motors..All models have a 5/16" shaft diameter so a 3/8" mounting hole is the correct size to drill in your case.
