Hamilton Model 22 WW2 Vintage Watch Mainspring - Alloy

This is a new old stock alloy mainspring for a Hamilton 22 movement (size: 35/s) from my stock of WW2 watch parts. The alloy mainsprings are in very short supply and difficult to find. The listing pictures show an example mainspring, example Hamilton 22 deck watch, and example Hamilton 22 mounted in gimbals (not to be confused with the larger master chronometer Hamilton 21 mounted in gimbals). This is new old stock Hamilton material. Note we service these and have other parts for sale. Email us with your needs.
