MARTIN Mainspring for Montilier caliber 62 Pocket Watch - Steel

MARTIN Mainspring (Lépine spring) for Montilier caliber 62 movements, plus perhaps similar ébauche movements, steel, new in envelope. The caliber 62 is a 18.5 ligne pocket watch and this mainspring may also fit other similar calibers. 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.
