Some notes regarding suspension spring material.

 Measuring the thickness is usually not an accurate way of determining your suspension spring requirement. It is best to identify your clock in the 400 day repair guide. This book also has drawings of the suspension units after assembly. This is a great help as the location of the fork on the spring is critical to the proper function of the clock. Springs are 5-1/2” long.

Here is a brief guide of the most popular suspension spring usage:

 

.0032 Full size Kieninger & Oberfield, Full size Kundo

.0023 Miniature K & O & miniature Kundo

.0023 Schatz “53” on back-plate (miniature)

.0040 Schatz with “49” on the back-plate

.0024 Schatz 1000 day, “54” stamped on the back-plate.

 

Suspension spring prices are:  $3.00 each, Buy three or more springs of the same size for $2.50 each.

Order by size in Inches.

Example:   .0019
