Kundo Miniature 400 Day Clock

Here is a Kundo miniature 400 day clock that I just finished giving a general service and repair. The pivots were in good condition, but it needed cleaning and a suspension spring replacement. The photo below shows the gears and anchor before the back plate was put on, and the complete clock: Here is a […]

Seth Thomas 8 Day Four Sided Top Shelf Clock

I recently overhauled this Seth Thomas shelf clock. This clock has an excellent movement design, as it runs very efficiently, allowing the use of thin mainsprings to reduce wear. Both the time and strike mainsprings in this clock are the original springs, and measure 11/16 inch wide and 0.015 inches thick. This is much thinner […]

Another 1950’s Regula 8 Day Cuckoo Clock Movement

I just overhauled another 8 day cuckoo clock from the 1950’s with a Regula movement. This one is interesting in that the back of the movement is labeled “Hubert Herr, Triberg” beneath the Regula logo. Later, Hebert Herr manufactured his own movements in competition with Regula. This movement differs from the previous one in having […]

1950’s Regula Cuckoo Clock Movement

I just overhauled a 1950’s cuckoo clock with a Regula 8 day movement.This older movement is different from the modern one, so I am illustrating it here. This movement needed to have the pivots polished and bushings installed. The pivots were not too badly worn, but some appeared to not have been well polished when […]

Speaker Mounting in Quartz Chime Clocks

Speaker Mounting in Quartz Chime Clocks

Some quartz (battery operated) chiming clocks sound much better than others. A major factor of sound quality is the mounting of the speaker that produces the sound. In some clocks, the speaker is mounted inside the case and the sound cannot project outward. These clocks have quiet, tinny sounding chime. The best clocks have the […]

The Upper Suspension Block Must Fit the Saddle Correctly

A recent repair job on a Kundo oval base 400 day clock reminded me that the upper suspension block must fit properly in the saddle. I cleaned the movement and replaced the suspension spring. It did not need any pivot polishing. After assembly, the clock ran, but the pendulum made a small rotation even when […]

Westclox Big Ben and Baby Ben Identification Guide

I have added recent research findings and more material to the guide, and it is available for download in […]

A Tale of Three Movements and a Clock (Ansonia Long Drop Regulator A)

About 1880, a fine Ansonia Regulator A, time only with calendar, was purchased for an office. The clock was enjoyed by many descendants of the original owner. It was well maintained, and always gave good service. In the late 1990’s, the clock was taken to a repair shop, and the repairman said he could not […]

Golden Hour Clock Repair Notes

Golden Hour Clock Repair Notes

1) Early Golden Hour clocks (made around 1953 and 1954) don’t use nylon pads to support the rotating gear ring. Instead, they have three slightly raised metal areas. When these wear down, the friction increases and can cause the clock to be unreliable. On 3-31-08 I repaired one by applying several pieces of black plastic […]

Seth Thomas Oak Kitchen Clock with 89E Movement

I overhauled the movement of this clock recently. One of the teeth on the escape wheel was too short, so I inserted a new tooth. Both mainsprings are original Seth Thomas mainsprings that measure 0.0165 inch thick. The strike speed is adequate, but I wouldn’t want the mainspring to be much weaker. The pendulum takes […]

New Baby Ben Alarm Clocks Have Lost Their “Soul”

When the Big Ben alarm clock was introduced in 1908, one of its important features was that the entire back of the case was the bell. This made the alarm ring louder and deeper than other alarm clocks of the time, which had a small bell on the top. When the Baby Ben alarm came […]
