I recently repaired this Schatz 1000 day clock. It is dated 10 56 (October 1956) on the back of the movement, and the front of the base has a presentation plate dated February 8, 1959. The picture on the right, below, shows the gears and the mainspring barrel. Note how large the barrel is compared to the other gears!

This Schatz standard-sized 400 day clock with diamond-shaped dial is dated 7 53 (July 1953) on the back of the movement. This clock has a glass dome with a hole in the top that fits over the brass handle. The base has brass leveling discs. The movement has two jewels (bearings), an uncommon feature in Schatz standard 400 day clocks (but all the Schatz miniature clocks have two jewels). This movement also has an extra mainspring on gear T4 (the 4th wheel in the gear train). It is visible in the left photo below. This is a very weak mainspring, and was used on a relatively small number of clocks. They found that it gave no improvement in performance.

Here is a nice example of the Schatz “London Coach” 400 day clock. This one is dated 3 56 (March 1956) on the back of the movement.

I disassembled and cleaned the movement and polished the pivots. I replaced the suspension spring with a new Horolovar 0.0024 inch thick spring (note that I used a 0.0024, not a 0.0023, as discussed in “Suspension Springs for Schatz and Kundo Miniature 400 Day Clocks”

I polished and lacquered the brass case parts except for the back panel.

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)

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:
