BESTFIT Mainspring 911M for NFT Caliber 38 - Alloy

BESTFIT Mainspring 911M for New Factory Tavannes 38, 41, 42, 43, 45 caliber movements plus perhaps other similar ébauche watches (including some variants of these calibers), white alloy, 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 pretty good job of representing the item.
