BESTFIT Mainspring 711M for Alpina 586, 588 & Felsa 294 - Alloy

BESTFIT Mainspring 711M for Alpina 586, 588, Felsa 294 and supposedly Rolex 1225, plus perhaps other similar ébauche watches, white alloy. See image 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.
