I think that this is such a pretty clock that I decided to show it here. The case has glass panels, and the movement is the Kundo miniature (Horolovar back plate no. 1406H). It was made in the 1950s. The case still has it original finish – not bad after about 60 years. When a case is this good, it is best to leave it alone, and not do any polishing.

This Schatz standard 400 day clock looks ordinary – but – it has model number 54 instead of 49 in the circle on the back. Movement model 54 normally refers to the Schatz 1000 day clock, and 49 is the model of their standard 400 day clock. I’ve seen several of these mis-stamped clocks, so perhaps a batch of them was made. The circle containing the 54 is 16.2 millimeters diameter, the same as that on the 1000 day clock.

Date 8 54 (August 1954) is stamped on the back.

This time-only long drop octagon clock by Ansonia Clock Co., has an oak case 31 3/8 inches tall and 17 1/4 inches wide. The minute hand is 5 9/16 inches long and the paper dial’s minute track is 11 inches outside diameter.

The movement is 8-day time only, and it is interesting that the pendulum is hung from the case backboard a couple of inches above the movement.

The original mainspring is 3/4 inches wide and 0.016 inch thick.

I overhauled the movement and polished the base and pillars of this clock. The owner had thought his clock would never look good again:

The movement is dated 4 54 (April 1954) on the back.

This Schatz standard 400 day clock is dated 2 55 (February 1955) on the movement. The pillars have a design that I don’t recall seeing before. Most pillars of this time have a series of maple leaves. These pillars have what appear to be oak leaves (or are they stylized Christmas trees?).

This clock has an unusual movement that may have been made by Laporte Hubbell ca. 1865. There is no name on the movement or the case. The paper dial is a replacement, as is the mirror in the front door.

The case is 44 inches tall and 18 inches wide. The length of the minute hand is 5 1/2 inches. The case is solid walnut (not veneered)  and there is mahogany veneer on the backboard behind the pendulum.

I’ve seen similar movements with a lever escapement pictured in books, but this clock has a pendulum and a Graham deadbeat escapement. The movement is time-only with double spring drive, and may run for a month on a winding.

The case may have had some modifications made, although it looks old. The front door just sets in place, with two brass strips at the top to hold it. The mirror is new.

Daylight Saving Time in the USA officially starts Sunday March 13, 2011 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 12th).

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.

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).

This clock strikes the hours and half-hours on a heavy coil gong. The case is 17 1/8 inches wide and 9 3/4 inches tall. The dial’s minute track is 4 3/8  inch diameter, and the minute hand is 2 1/4 inches from center to tip. The video below shows the clock striking:

When the clock arrived in my shop, the finish had been stripped from the case. I stained it with brown mahogany gel stain, and finished it with spray semi-gloss Deft lacquer.

This movement is a good example of an American clock movement with weak mainsprings. The springs are open (no barrel), 3/4 inch wide, 0.014 inch thick, and about 8 feet long. Many American movements have stronger springs (0.0165 – 0.018 inch thick). A 0.018 inch thick mainspring provides over twice the force of a 0.014 inch thick spring (because the force is proportional to the thickness cubed).

This movement has a strip deadbeat escapement with a very small escape arc (the minimum swing needed for the clock to tick). The running arc is over 3 times the escape arc, showing that the thin springs provide plenty of power for this movement. Unfortunately, it is difficult to find weak enough springs if replacements are necessary. Springs that are too strong will cause wear. The video below shows a closeup of the escapement, and shows the amount of pendulum swing, starting from the minimum:
