Sessions Tambour Mantel Clock, Made in 1938.

I recently overhauled this clock. The repairs included: Polished all of the train wheel pivots (some were rough when the clock left the factory); Installed 10 bushings (including rear time mainwheel bushing). One bushing had been installed by a previous repairer. It was crooked in the movement plate. To correct this, I installed a bushing […]

Gilbert “Navy No. 26” Oak Kitchen Shelf Clock

I recently repaired this clock. The movement was ugly to start with, because a previous repairer had soldered bushings to the front and rear escape wheel pivot holes (see slide show below). The pivots were bent in the process. I removed the unsightly bushings, removed the solder and straightened the bent pivots. The pivots were […]

Seth Thomas Adamantine Clock

I repaired this Seth Thomas Adamantine clock last week. The movement is No. 89C, a popular movement for mantel clocks, using a semi-deadbeat escapement. This one needed a lot of work, including making a new dial (it had a terrible replacement dial), making a new front strike mainwheel bushing, and replacing both click rivets and […]

Replacing Mainsprings in American Antique Clocks

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 […]

Gilbert Tambour Mantel Clock, 1919

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. The brass bushings can be reamed and bushings installed, just like a movement with normal brass plates. This movement needed all the train wheel pivots […]

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 […]
