BESTFIT Mainspring 415C for AS 1017, 1042, 1234, Bulova 5AD, 5AH & Buren 360 - Alloy

BESTFIT Mainspring 415C for AS caliber 1017, 1042, 1234, Bulova caliber 5AD and Buren caliber 360 movements plus similar ébauche watches, white alloy. 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.
