BOREL Mainspring A4516-G for Felsa caliber 380, 382 - Alloy

BOREL Mainspring A 4516-G for Felsa 380, 382 caliber automatic movements plus perhaps similar ébauche watches, white alloy, with detached brake, new in envelope. 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 barely adequate job of representing the item.
