Elgin Watch Mainsprings

Mainsprings for American made Elgin watches can also be ordered at the bottom of the page by the serial number stamped on the movement.

The mainsprings listed here are by factory part number for the spring and the measurements for those who have the gauge and skill to measure a spring. To find factory part number, which is listed for each spring listed you would need a serial number book as well as Elgin parts book by watch grade. Old time watchmakers had these books and sometimes they can be purchased at local AWI or NAWCC meeting. I have seen serial number information on American Watches posted on a few websites over the past five years.
