I recently repaired this Schatz cuckoo clock. It has the KU50 movement, and the case is the bird and leaf style with light color shaded finish. See my previous post, Four Schatz Cuckoo Clocks, for some other case styles. The top piece of the case isn’t shown in the photos.

Dimensions: Height (no top) 11 1/4 inches, width 8 1/16 inches, dial diameter (black part) 2 7/8 inches.

Most 400 day clocks have a round brass base that is polished and lacquered.

Some nickel-plated 400 day clocks were made. These are uncommon, and I see only 1 or 2 of these per year in my repair shop.

I recently repaired a copper plated Schatz 400 day clock! It is the only one I have ever seen.

The photos above show 3 examples for comparison: a Kundo standard with nickel finish (uncommon), a Schatz standard with copper plated finish (rare), and a Kundo standard with brass base (the most common 400 day clock)

5. Schatz Standard 400 Day Clock with “Holey” Dome

This is the most unusal Schatz 400 day clock I’ve seen – it has a copper plated finish. It is the only one I’ve see in all my years of collecting and repairing clocks. When the clock came in for repair, the finish on the base had been damaged by attempted polishing. The movement and bezel still looked good!

I sent the following parts to Ken’s Clock Clinic for replating:

• Pendulum parts: hook, 8 half-ball covers, 4 arms, regulator assembly, decorative washer and center assembly;
• Case parts: 2 pillars, 4 pillar ends, platform, base cup, base cup screw, base, 3 finials.

The movement plates, suspension guard, guard washers, ratchet, ratchet cock, ratchet cock washer, bezel, saddle, saddle washer, saddle bridge, plate washers are copper plated. The hand nut, gear train and motion work are not copper plated.

This clock was made around 1940 or 1950. The dial has no maker’s name, and the pack plate says Jahresuhrenfabrik 49 Germany in a circle.

I didn’t clean the movment plates in cleaning fluid for fear of damaging the lacquer or the copper plating. I pegged and smooth broached the pivot holes to clean them. The movment is identified in the Horolovar 400 day clock book as plate no. 1278.

See more pictures.

I thank Ken of Ken’s Clock Clinic for taking on this plating project. The base was especially challenging to do.

I recently repaired 3 Schatz cuckoo clocks, and have photos of another I repaired several years ago. These examples show 4 case styles: maple leaf, hunting, oak leaf and multi-color. An earlier post shows the movement and gears of the Schatz hunting model cuckoo clock.

Schatz introduced their cuckoo clock movement in 1950, and probably made cuckoo clocks up until the late 1950s or early 1960s.

The movements are the same design, but I noticed some variations:

• There are 2 different logo circles on the back plate. The earlier ones say: ”Jahresuhrenfabrik Germany” around the circle and “50″ in the center.  The later ones say: “Aug. Schatz & Sohne Germany” around the circle, and “KU 50″ in the center.
• One of the “50″ movements has a brass lever to open and close the cuckoo door, the others have a blued steel lever.
• The clocks with “50″ movements had lighter weights that clocks with the “KU 50″ movement. See bottom of article for a list of weights.

See a Schatz sales brochure that shows 2 models of cuckoo clock.

See more photos of the maple leaf cuckoo clock (has a “50″ movement).

See more photos of the hunting cuckoo clock ((has a “50″ movement).

See more photos of the oak leaf cuckoo clock (has a “KU 50″ movement).

See more photos of the multi-color cuckoo clock (has a “KU 50″ movement).

(Three of them don’t have their top piece in the pictures.)

I measured the chains on the multi-color clock: 42 links per foot, 1.2 mm wire diameter.

Weights:

• Maple leaf cuckoo clock: about 2 pounds 12 ounces each.
• Hunting model cuckoo clock: 2 pounds 12 ounces and 2 pounds 14 ounces.
• Oak leaf cuckoo clock: 3 pounds 5 ounces and 3 pounds 6 ounces.
• Multi-color cuckoo clock: 3 pounds 4 ounces and 3 pounds 5 ounces.

I believe the above list is in chronological order, it seems that Schatz used heavier weights for later clocks.

The Schatz is different from most cuckoos in that there are separate controls for door and bird – bird goes in and out with each cuckoo while the door stays open. Here is a video showing this:

I recently repaired this square dial Schatz 400 day clock made in November 1953. I cleaned the movement, polished the pivots and the anchor pin, and replaced the suspension spring. These clocks use a 0.004 inch thick Horolovar suspension spring. I also polished and lacquered the base and pillars. The square dial clock is not as common as the round dial model.

5. Schatz Diamond Dial 400 Day Clock Made in 1952

This Schatz (Jahresuhernfabrik) standard size 400 day clock was made around 1949 – 1950. It has some differences from those made around 1950 – 1951. The “early” features include:

• No name on the dial;
• short sliding tube on suspension guard;
• the dial is secured with taper pins (instead of collars with screw);
• the minute wheel is held by a cock instead of a screw, and the canon pinion is larger in diameter than the later style.

This clock has its original instruction sheets.

The single sheet appears to have been hand typed, and is signed “Devon Sales Company, Devon, Connecicut”

The 4 page instructions were printed in Germany and contain both German and English text. They contain the heading “Directions for setting up ORIGINAL SCHATZ 400 day lever clock” The instructions explain raising the sliding tube on the suspension guard, hanging and starting the pendulum, the purpose of the cup in the base, how to tell if the clock is out of beat, how to adjust the beat, and regulating the clock. The instructions don’t cover winding and setting the clock, perhaps they assumed that people already knew how to wind and set a clock (which was probably true in 1950!)

This Schtaz standard size 400 day clock was made in August 1952. It has a special glass dome with a hole in the top for the handle to protrude. The handle has a spring loaded brass dust washer which the dome presses down slightly when it is set in place. The dome is 5 1/2 inches in diameter, 9 3/8 inches tall, with a 1 inch diameter hole. The hole in the dome should have a brass trim washer around it, which is missing on this dome.

The movement on this clock is unusual. It has one jewel bearing in the front plate (for the anchor). Most standard 400 day clocks have no jewels (however, the Schatz miniature 53 movement always has 2 jewels). There were a few 2-jewel standard Schatz movements, but this is the first I’ve heard of with one jewel!

The movement is characterized as Horolovar back plate no. 1281. The date code is 8 52.
