BESTFIT Mainspring 514E for Buser 150 & Felsa 349 thru 352 - Alloy

BESTFIT Mainspring 514E for Buser caliber 150 and Felsa 349, 350, 351, 352 plus perhaps similar ébauche watches, white alloy, new in envelope. See images for precise mainspring specifications. I likely have several of these so the one you get may vary slightly from the image. 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.
