I recently repaired this clock and polished and lacquered the base. It is identical to one I repaired several months ago, even having the same date code (11 54). I polished the pivots and replaced the suspension spring. The original mainspring is in excellent condition, and opened out to over a foot in diameter when removed from the barrel.

Horolovar back plate no. 1010. Uses 0.0024 inch thick suspension spring. Repair job 5167.

Schatz (Aug. Schatz & Sohne) made this 1000 day clock in November 1954 (it has date code 11 54 on the rear of the movement). This is the earlier movement style with straight legs. Around mid-1955, Schatz changed the plate design to have curved legs (see this article for a view of the curved leg design).

I cleaned the movement, polished several pivots, and replaced the mainspring and suspension spring.

Below are some photos, there are more in my Picasa Web Album.

Here is a video of the clock:

Why I Replaced the Mainspring

The original mainspring had rust and sticky green gunk on it. An earlier repairer soaking the entire mainspring barrel in cleaning fluid instead of removing the spring for cleaning probably caused this.

I recently restored this Schatz rectangular case 1000 day clock. It is dated 3 56 (March 1956) on the movement. The movement needed cleaning and two pivots polished. The suspension spring was replaced. The case and pendulum were disassembled, the old lacquer removed, the parts polished, and the parts with brushed finish were cleaned with a Scotch-Brite pad. Then the parts were sprayed with lacquer. The movement plates, bezel and hands were cleaned and lacquered also.

In 1954, Schatz introduced their 1000 Day Clock. The 1000 day clock is based on Schatz’s miniature 400 day clock movement (see Why 400 Day Clocks Run So Long). A larger mainspring, with about 2.5 times the amount of energy storage, is used, but the gears and escapement are similar. The pendulum makes 10 rotations per minute.

Here are videos of the 1000 day clock in operation, and a closeup view of the escapement:

Here are some photos of the 1000 day clock:

This clock is dated 8-57 (August 1957) on the movement and is part of my clock collection.

The 1000 day clock uses a 0.0024 inch thick Horolovar suspension spring, or complete suspension unit number 10B. See this post for information on ordering suspension springs or units.
