BESTFIT WALTHAM MAINSPRING 37s #2232

This item is part of a retired watchmakers estate I purchased. The mainspring is NOS in the original envelope. These mainsprings are getting harder to find so get them while you can. Thank you for looking at my auction and please look at my other auctions. I have other mainsprings. All items are sold "as-is" unless otherwise noted.

I combine shipping on all mainsprings and watch parts. Just add all items to cart and check out and it will combine the shipping charges.
