Many antique American clocks have mainsprings that are stronger than necessary. The most popular replacement mainsprings are even stronger than the originals. These strong replacement springs cause wear to the main wheel teeth and pivot holes. Thinner mainsprings are available, and should be used to replace old replacement springs that are too strong. Here is […]

Seth Thomas Dark Mahogany Tambour Mantel Clock, ca. 1920

This Seth Thomas tambour mantel clock is very plain, yet is a great example of an old clock of classic design that will be reliable for many years. It has the No. 89 movement, very reliable and efficient, and one of their best movements, in my opinion. The clock is 17 inches wide, 9 1/8 […]

E. N. Welch Oak Kitchen Clock

I recently repaired this clock, and replaced the mainsprings with longer, thinner ones to make the clock keep better time and reduce mainwheel tooth wear. The dial and hands are original, unfortunately, part of the top of the case is broken off. The clock was made around 1880 – 1890. The E. N. Welch Mfg. […]

Waterbury Tambour Mantel Clock ca. 1920

This Waterbury tambour mantel clock was made around 1920. The movement plates are steel that have been given a thin brass plating. Brass bushings were inserted in the plates so that the pivots (steel gear shafts) can turn in brass holes as usual (steel on steel would cause severe wear). See more photos. This clock […]

Seth Thomas Lyre Movement in Fancy Round Drop Case

My customer sent this movement to be repaired, because the clock fell off the wall, bending the center arbor and causing 2 gears to come out of the movement plates. The movement has the nice thin original Seth Thomas mainsprings. Time Mainspring: 11/16 inch wide by 0.0165 inch thick. Strike Mainspring: 11/16 inch wide by […]
