Schatz introduced their 1000 day clock in 1954. There are two case styles: round base with glass or plastic dome, and rectangular base with brass cover having glass or plastic panels. A 1000 day clock can be identified by the “54” in a circle on the back of the movement. (Note: a small number of Schatz standard 400 day clocks were mistakenly marked "54".)
Bill's Clockworks is located in Flora, Indiana (about an hour north of Indianapolis). If you are too far away to visit us, we'll be happy for you to send your 1000 day clock to us for repair. Packing and shipping instructions are given below.
We take the time to repair your clock properly. The movement of your clock is disassembled, cleaned and examined. We polish any rough pivots, replace the mainspring if necessary, repair or replace any damaged parts, and do a final cleaning. Then the movement is assembled, lubricated, adjusted and tested. We guarantee our work for two years.
(Polishing is available only as part of an overhaul - it is not available as a separate service):
(Note: don't polish the clock yourself unless you are prepared to disassemble the parts before polishing. If left assembled, polish will remain in the joints and crevices, possibly causing corrosion after a time.)
After receiving your clock, I will examine it and I will examine it let you know if the repair cost will exceed the estimate given above. If you decide to have the clock returned without repair, the charge will be $60 for the estimate and return shipping.Note: If the clock has been repaired by someone else and it still doesn't work, I will be happy to repair it, but the repair bill may be significantly higher than stated above. I recently received a clock that had unsightly blobs of solder and bent wheel teeth, requiring replacement of two major parts.
You may send your Schatz 1000 day clock now for repair, and it will probably be finished within 5 weeks. Please contact us if you need expedited repair service.

Please include a note with your 1000 day clock with your name, address, e-mail address and phone number. Please state if you would like the base polished. I'll e-mail, call or write you to acknowledge the receipt of your clock when it arrives. If the repair will cost more than the above prices, I'll notify you.
Be very careful when unpacking the clock and removing the bubble wrap.
After following the instructions for unlocking the pendulum, and leveling the clock, start the pendulum as follows:
Rotate the pendulum gently one-half (1/2) turn only and release it. The clock will then start running.
The suspension spring (thin flat wire) that that the pendulum hangs from IS VERY DELICATE and must not be bent or twisted in any way. Damage of the suspension wire by the customer is NOT COVERED BY THE WARRANTY.
The Schatz 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 (except for the barrel and second wheel) and escapement (except that the anchor has a longer arbor) are the same. The pendulum makes 10 rotations per minute.
Below are some movies showing 1000 day clocks in operation (note - 1000 day clocks do not strike or chime, the sounds you hear are in the background):
One thousand day clocks (and many others by Schatz) have a date stamped on the back of the movement. There will be digits for the month and the year. For example, 12 57 means December 1957.
See my blog for examples of 1000 day and 400 day clocks I have repaired.
I unwind the mainbspring and take the movement apart. This includes taking the mainspring out of the barrel. The pivot holes are cleaned with alcohol to remove dried and sticky oil, then the pivot holes are polished. The mainspring, ratchet, barrel, gears, plates and other parts are cleaned and inspected for damage. Any damaged parts are repaired or replaced. Any rough or pitted pivots are polished and cleaned again. The pivot holes are cleaned with pegwood, then the movement is assembled and lubricated. A new suspension spring unit is assembled (if needed). The movement is tested, first with minimum power, then fully wound, to verify that the fork is at the correct location on the suspension spring. If the suspension guard is missing, it is replaced. The clock is run and regulated for several days.
Schatz introduced their 1000 day clock in 1954. There were two case styles: round base with glass or plastic dome (glass came first and was changed to plastic around 1956), and rectangular base with brass cover (first with glass panels, then plastic). The first movements had straight legs, and were changed to the more graceful curved legs around mid-1955. The round base model came with several different styles of decoration above the dial. Most of the dials have small radial Roman numerals, but a few have small upright Arabic numerals.
