Schatz Standard 400 Day Clocks – When in Doubt, Replace the Suspension Spring!

A Schatz standard 400 day clock didn’t run well after repair. I had cleaned the movement and adjusted the fork on the suspension spring, yet the pendulum rotation was only about 3/4 of a turn with the mainspring fully wound. I installed a new mainspring, and the motion was slightly less. I polished the pivots, […]

Some Schatz London Coach 400 Day Clocks Need A 0.0024 Inch Suspension Spring

The Horolovar 400 Day Clock Repair Guide specifies a 0.0023 inch thick suspension spring for the Schatz model 53 miniature movement. I just repaired one that ran too slow with a 0.0023 inch spring, so I installed a 0.0024 and it keeps good time (my repair job no. 5212). The pendulum looks normal, but perhaps […]

Kundo 400 Day Clock – Locking Suspension Guard

On many 400 day clocks, the pendulum can be locked in place for shipping and there is a metal or plastic guard to protect the suspension spring. On earlier clocks, […]
