Replacing Mainsprings in American Antique Clocks

Most spring driven American antique clocks are overpowered (they have springs that are stronger than necessary). Even at age 100 years (give or take) the mainsprings are almost always strong enough to operate the clock reliably, assuming that the clock has been repaired properly, including POLISHING THE PIVOTS and installing bushings. A spring should be […]

I just finished repairing this 1919 Gilbert Mantel clock (the movement has “19” stamped on the front plate, meaning 1919). This movement has nickel plated steel plates with brass bushings.

Schatz 1000 Day Clock

In 1954, Schatz introduced their 1000 Day Clock. The 1000 day clock is based on Schatz’s miniature 400 day clock movement (see Why 400 Day Clocks Run So Long). A larger mainspring, with about 2.5 times the amount of energy storage, is used, but the gears and escapement are similar. The pendulum makes 10 rotations […]
