HR Quick Fit Mainspring K599 for Blancpain 41, Judex 120 - Alloy

HR Quick Fit Mainspring No K599 for Blancpain caliber 41 & Judex caliber 120 movements plus perhaps other watches as well, white alloy, new in envelope. See images for further data and 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 an adequate job of representing the item.
