BESTFIT Mainspring JA208 for 16s Hamilton No. 534 / 718047 - Alloy

BESTFIT Mainspring MS-JA208 for Hamilton 16s Movements, Factory No. 534 / 718047, T-end, alloy, new in possibly unsealed package. See images for precise mainspring specifications. I likely have several of these so the one you get may differ slightly from the images. I specialize in hard to find watch parts so I usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
