Schatz Standard 400 Day Clock with 2 Jewels, Auxiliary Mainspring and Adjustable Pallets

May 20, 2015 | By | Reply More

This Schatz standard 400 day clock is from 1953 and has several unusual features:

  • The movement has 2 jewel bearings (most standard size movements have no jewels). The jewel bearings don’t affect how well the clock works, and may have been a sales feature;
  • It has an auxiliary mainspring and barrel on the 4th gear. Some clocks from the early 1950s have this, they were trying to make the timekeeping stay more constant as the clock ran down. It was not successful;
  • The top of the clock has a handle that goes through a hole in top of the glass dome;
  • The anchor of the escapement has adjustable pallets (most Schatz standard movements have a solid body anchor with non-adjustable pallets).

The adjustable pallet anchor is not really a good feature, as it tempts a tinkerer to move the pallets, putting the escapement out of adjustment. The factory set the pallets correctly, and they do not need adjustment. The photos below show the adjustable pallet anchor and a regular, solid body anchor.
