BESTFIT Mainspring 612M for Rolex H/HT, 700, 710, 760, Reconvillier 2320, 2322 - Alloy

BESTFIT Mainspring 612M for Rolex caliber H/HT, Reconvillier caliber 2320, 2322 movements plus 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 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.
