Watch 431: Hairsprings

July 28, 2025 @ 8:00 am - August 1, 2025 @ 5:00 pm UTC-4

$1195

This class encompasses the basics of hairspring manipulations. You will start with a uncolletted, unstudded hairspring. One error at a time will be introduced, and correction and the logic behind the repair will be discussed prior to the correction. Techniques will be shown and through this educational experience strong basics should begin to emerge. Simple bends and multiple bends will be addressed. Correction of errors in the flat will also be a part of this seldom offered program. The finale will be the correction of multiple errors in a balance installed within a stripped mainplate and bridge. This class will touch upon truing the hairspring at the collet, safe removal, installation, manipulation, centering in the round and flat, regulator pins and more.

Cost: $1195 for AWCI members / $1345 for non-members

Class Schedule: 5 days, Monday – Thursday 8:00 a.m. – 5:00 p.m. Friday 8 a.m. – 3 p.m.
