I just repaired this Schatz 1000 day clock made in February 1955. This is the round model, and this one is old enough to have a glass dome (the plastic dome model have an extra piece on the base to engage the dome’s locking lugs).

I polished most of the brass pieces, and installed a new old stock dial.

Repair job 6070. The movement is Horolovar back plate no. 1010. It uses a .0024 inch thick Horolovar suspension spring. I polished the pivots. Polishing the barrel pivots on the barrel arbor makes these clocks run better.

This is such a pretty clock, and I really like this style, so I had to show it here. This was made by Kundo (Kienineger & Obergfell) in Germany in the 1950s, and has the diamond-shaped dial. It is a standard-size 400 day clock.

Job 5857. Cleaned, one pivot polished, new suspension spring (Horolovar 0.0032 inch thick) installed.

Schatz Midget 400 Day Clock Made in 1968This Schatz “Midget” 400 day clock was made in September, 1968 (date code 9 68 on the back of the movement). The midget is identified by “JUM/7″ in the circle on the back. The pendulum on these clocks goes faster than on the miniature models – it makes 12 half-oscillations per minute.

Repair job 5906. Horolovar back plate no. 1013B. I polished the pivots, replaced the damaged barrel cap, and replaced the suspension spring with 0.0023 inch thick Horolovar spring. (The Horolovar repair guide calls for a 0.0022 inch spring, but that was too thin and the clock ran slow, so I used a 0.0023 inch thick spring. This midget movement makes 12 beats per minute, not 10 as stated in the Repair Guide.)

Here is another Kundo standard 400 day clock with large dial, as I described in Kundo and Welby Standard 400 day Clocks with Large Dial.

This example has “wings” on the movement to make it look like the wide movement that was first used on Kundo standard 400 day clocks. It has the older type of pendulum like the Welby clock had, but has the short (later) type of movement mounting nuts

I recently repaired this Schatz standard 400 day clock. The dial is brass with embossed numerals, painted ivory. The hands are thin stamped brass, to reduce their weight.

I really like these Schatz 400 day clocks with Roman numerals. I’ve shown this model before, but I like it so much that here is one I just repaired. The dial has the Schatz logo, and the movement has no date, so it was made ca. 1951 – 1952. I polished the base and pillars.

Repair job 5760. Horolovar back plate no. 1278. 0.004 inch thick Horolovar suspension spring.

This is a Schatz ”Bermuda Coach” 400 day clock. It has the Schatz miniature 400 day clock movement (Horolovar back plate no. 1013a) and a date of 9 55 (September 1955) on the back. The height including the handle is 8 1/2 inches. The front and side panels are plastic. The brass rear panel has a polished front and gold painted rear.

See more photos (including a photo of the clock before polishing).

This 400 day clock with disc pendulum was made around 1900 – 1910. The brass base has a wooden insert. There is no suspension guard over the suspension spring, so I had to be extra careful in packing it for shipping.

See more photos.

Repair job 5689. The movement is Horolovar back plate number 1471. The suspension spring is .004 inch thick thinned by 30 strokes of 600 grit abrasive paper. New 19 x 36 mainspring.
