Seth Thomas Poise-1 Electric Alarm Clock, Dated 1977

August 16, 2017 | By | Reply More

I repaired this Seth Thomas Poise-1 (model SS7-Q) electric alarm clock because of its sentimental value to the owner. I was particularly interested in this clock because I have the earlier version (Poise E 861-000) that my parents received as a wedding gift in 1954. The case is the same, the older version has the alarm dial on the back, the newer version has an alarm set hand on the face. The older version has a power outage indicator in the dial, the newer version doesn’t.

The case is mahogany with brass trim, the while metal face has Roman numerals and fancy hands. The clock is 5 1/4 inches tall and 5 5/16 inches wide.

The clock has the General Time M4 motor, a self-starting synchronous motor with open rotor. A rotary alarm hammer with three discs hits the large internal bell.

The clock’s owner stamped the date DEC 15, 1977 on the bottom. The 1974 Seth Thomas catalog shows this clock on page 13.

Repair job 6867. I replaced the motor and cord, and cleaned and lubricated the gears and motor.
