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

The most delicate part of a 400 day clock is the thin wire called the “suspension spring” that holds the pendulum and controls its rotation. 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, […]

Seth Thomas 44 AG Clock Movement

I repaired this Seth Thomas 44 AG clock movement. It uses 11/16 inch wide mainsprings, and has 4 gears in each train (time and strike). The movement has a strip deadbeat escapement, and stopworks for time and strike mainsprings. This shape of movement is sometimes called a “hip” movement because of the shape of the […]

Schatz Miniature 400 Day Clock, March 1956

A couple brought in this clock that they received it as a wedding gift over 50 years ago. They told me that the clock was put away in its box and was forgotten until recently. I disassembled and cleaned the movement. The only problem found was that the pendulum hook had come unscrewed. This clock […]

Schatz “London Coach” 400 Day Clock, April 1960

This beautiful little clock was given to my customer’s mother in 1960, but it never worked for more than 5 minutes. It spent its life sitting idly on a shelf, and was given to my customer recently. I disassembled the movement and cleaned it. A couple of the pivot holes were slightly too tight, and […]

Mainsprings for Seth Thomas 89C Clock Movement (6-18-10)

Mainsprings for Seth Thomas 89C Clock Movement (6-18-10)

When this movement came in for repair it had extremely strong replacement mainsprings from Germany (the ones that uncoil to over 20″ diameter when released). I don’t like such strong springs in American clock movements, especially the Seth Thomas 89 movements, which are efficient). After routine repair (pivot polishing, bushing) and not so routine repair […]

Measurement of Mainsprings for 8-Day American Antique Clocks, June 2010

Over the past three years, I’ve posted about mainsprings for antique American clocks. I started with a post on June 12, 2007 about a mainspring from Merritt’s Antiques. Most clock parts distributors offer a “standard” American loop end 8-day mainspring 3/4 inch wide by 0.018 inch thick and 96 inches long. These springs are too […]

I recently overhauled this Waterbury walnut cased shelf clock made around the 1880s or 1890s.This clock has a nice original painted dial. The hour hand is the original solid spade hand. The minute hand has been replaced. This clock movement is known for running on thinner than average mainsprings. Even with the weaker springs, there […]
