BESTFIT Mainspring 511K for Bulova 10AN, 10AX, 10AE, Font 324, Enicar 410, 412, 1002 - Alloy

BESTFIT Mainspring 511K for Font 324, Bulova 10AN, 10AX, 10AE, A.S. 1361, 1336 & Enicar 410, 412, 1002 caliber movements plus perhaps similar ébauche watches, white alloy, new i envelope. See images for precise mainspring specifications. I likely have several of these so the one you get may differ slightly from the images - none of them are in the jiffy-pak that Bestfit often used. 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.
