Schatz Standard 400 Day Clock with Roman Numeral Dial, ca. 1950 – 1952

Bill Stoddard — Tue, 01 May 2012 12:00:43 +0000

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. 1950 – 1952. I polished the base and pillars.

Jahresuhrenfabrik Disc Pendulum 400 Day Clock

Bill Stoddard — Thu, 26 Apr 2012 12:00:35 +0000

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 place number 1471. The suspension spring is .004 inch thick thinned by 30 strikes of 600 grit abrasive paper. New 19 x 36 mainspring.

Schatz Standard 400 Day Clock with 54 Instead of 49 in Circle on the Back

Bill Stoddard — Mon, 16 Apr 2012 12:00:49 +0000

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.

Schatz Square Dial 400 Day Clock, 1954

Bill Stoddard — Sun, 15 Apr 2012 01:03:53 +0000

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.

Schatz 1000 Day Clock, 1956, with 1959 Presentation Plate

Bill Stoddard — Sat, 14 Jan 2012 20:49:36 +0000

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!

Schatz Diamond Dial 400 Day Clock with Hole in Dome

Bill Stoddard — Sat, 14 Jan 2012 20:14:19 +0000

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.

Schatz “London Coach” 400 Day Clock, March 1956

Bill Stoddard — Wed, 07 Dec 2011 12:51:20 +0000

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.

Hermle 1950s 400 Day Clock

Bill Stoddard — Sat, 26 Nov 2011 01:57:41 +0000

Here’s a Hermle 400 day clock form the 1950s that I repaired recently. Hermle 400 day clocks are not very common. I get many Schatz and Kundo 400 days, but see a Hermle only every couple of years.

The dial has a 3 15/16 inch minute track, and the minute hand is 2 inches long from center to tip. The original instructions are with the clock.

The pivots were rough on this clock, and I think they left the factory this way. I polished them all.

Repair job 5589. Horolovar back plate number 1103. Suspension unit 25A, with fork raised to prevent fluttering (5.2 mm space bvetween upper block and fork). 0.0033 inch Horolovar suspension spring.

Kundo Nickel Plated 400 Day Clock Made about 1950

Bill Stoddard — Wed, 31 Aug 2011 11:55:55 +0000

This Kundo standard-sized 400 day clock has a nickel plated finish instead of the common plain brass. It has a wide-plate movement so I believe it was made on the early 1950s. The back plate has no name, just the Kundo logo in a circle. It uses a 0.0032 inch thick suspension spring. I didn’t do a full repair on this clock – just replaced the suspension spring. The gears are not nickel plated.
