Seth Thomas 8-Day OG Shelf Clock

I recently repaired the movement of this Seth Thomas 8-day OG shelf clock. Before repair, the clock would run for several minutes and then stop. While running, it would go in and out of beat (the ticking would sometimes be even and sometimes uneven). The movement was taken apart and cleaned. The major problem was […]

Seth Thomas Adamantine Clock Movement with Thin Time Mainspring

I recently repaired a Seth Thomas Adamantine mantel clock made around 1905. It has a No. 89 movement. This movement is very efficient in operation, due to the use of a deadbeat escapement. Even with a thin time mainspring, these movements typically take an excellent escapement motion. This particular example has thin, original mainsprings. Time […]

I thought it would be fun to show all the parts of this movement. In the first photo it has been disassembled and is ready for cleaning. You can tell it needs cleaning by the black deposits on the pivots (the ends of the gear shafts that turn in the holes in the brass movement […]

Junghans W202 Clock Movement

I repaired this Junghans W202 clock movement. It has the numbers 33 3 on the back which may be a date code of March, 1933; does anyone know if this is correct? The biggest weakness of this movement is that the mainsprings are attached to their barrels by tongues cut out of the barrel wall […]

Date Codes on Late 1940s Seth Thomas Electric Clocks

The owner of an old clock often asks, “How old is it?” Some clockmaking companies helped us answer this question by putting date codes on their products. (Actually, date coding was done for business reasons, including facilitating the ordering of spare parts.) Seth Thomas is one company that put date codes on many of their […]

1949 – 1950 Schatz 400 Day Clock With No Name On Dial

400 day or “Anniversary” clocks were introduced in the 1880s in Germany. Their popularity had its ups and downs, reaching a peak in the 1950s, when many U.S. servicemen sent clocks home as gifts. For years, most 400 day clocks did not have the maker’s name or country on the dial. Later (1920s?), “Made in […]

These cases are durable, and can usually be polished to look very nice. Sometimes the colors fade with age. Adamantine clocks were made from about […]
