This clock has cream color painted base, pillars, dial and pendulum balls, with hand painted flowers on the dial. It is dated 10 52 (October 1952) on the back of the movement.

Here is a video:

Repair job 5147. The movement is Horolovar back plate no. 1281, dated 10 52 (October 1952). It uses a 0.004 inch thick Horolovar suspension spring. I cleaned the movement and polished 10 pivots.

This popular 400 day clock from the 1950s has an oval base and dome. It uses the Kundo miniature 400 day clock movement with a 0.0023 inch thick Horolovar suspension spring. It has a pendulum locking device at the bottom rear of the movement.

Here is another “Plymouth” tambour mantel clock by Seth Thomas (see this post for two others). This one does not have a date code, I estimate that it is from the early 1930s. It has a no. 89I movement that strikes the hours and half-hours on a coil gong. The movement has a code of R-6 on the back.

The case is 19 3/4 inches wide and 9 1/4 inches tall. The dial has a 4.5 inch time track, and is aluminum with embossed and painted numerals.

The movement has the original mainsprings that still open up very far and provide plenty of power. They are 3/4  inch wide loop end springs. The thicknesses are:

Time mainspring: 0.017 inch

Strike mainspring: 0.0167 inch

Job 5146. I had last repaired this clock over 10 years ago, and it just needed to be disassembled and cleaned to make it run well again.

This beautiful clock was made about 1950 and has nickel-plated base, pillars, movement plates, pendulum, suspension guard, etc. These nickel-plated models are not nearly as common as the standard brass model.

Here is a Jahresuhrenfabrik (Year Clock Company) 400 day clock made about 1949 in Germany. This company’s clocks were given the name Schatz soon after this. This clock has an attractive and unusual style of bezel around the dial, with wide front section and embossed decoration. The movement has the same gearing as older Jahresuhrenfabrik movements. This is the first movement with 49 in the circle on the back plate, characterized by not saying “No (0) Jewels Unadjusted.”

The dial is held by taper pins (later ones used collars held by a screw). It has the early style of motion work, with a cock holding the minute wheel. Later motion work has a screw through the center of the minute wheel.

The suspension guard has a short slider. It is probably original, although it looks like a later one with the top part cut off.

The base is like that on Kundo clocks of the period. I’ll need to see more examples to know if it is original to this clock.

Daylight Saving Time in the USA officially starts Sunday March 14, 20010 at 2:00 a.m. You will need to set your clocks forward one hour. I recommend doing this before you go to bed on Saturday night (March 13th).

On the vast majority of clocks, it is okay to set the hands forward one hour. When setting the hands, you should pause at each time the clock will strike or chime. On clocks where you set the hands directly (not having a time set knob), move the minute hand (long hand), and the hour hand will automatically follow.

Hermle Clocks (such as the ones I sell at Bill’s Clockworks): You may turn the minute hand ahead one hour, pausing each quarter hour for a chiming clock or each half hour for a striking clock.

Cuckoo Clocks: Move the minute hand ahead one hour, pausing at the hour and half hour for the clock to cuckoo.

Grandfather Clocks: Move the minute hand forward one hour, pausing at each quarter hour for the clock to chime.

Chelsea Ship’s Bell Clocks: Turn the minute hand ahead pausing at the hour and half hour for the clock to strike.

Antique American wall, mantel and shelf clocks: Move the minute hand forward one hour, pausing at the hour and half hour for the clock to strike.

French Antique Clocks: Move the minute hand forward one hour, pausing at the hour and half hour for the clock to strike.

400 Day Clocks: Move the minute hand forward one hour.

IMPORTANT: DO NOT FORCE THE MINUTE HAND. IF YOU FEEL AN OBSTRUCTION, STOP MOVING THE HAND.

IMPORTANT: DO NOT MOVE THE HOUR (SHORT) HAND – IT WILL MOVE BY ITSELF AS YOU MOVE THE MINUTE HAND.

DISCLAIMER: I AM PROVIDING THIS INFORMATION AS A FREE SERVICE. I AM NOT RESPONSIBLE FOR ANY PROBLEMS CAUSED BY FOLLOWING THESE DIRECTIONS.

Marine or Ship’s Chronometer: IT IS BEST TO LEAVE THE HANDS ALONE. Consult a specialist before setting a chronometer. It is best not to set the hands, just record the chronometer’s error each day.
