Marco Marshalloy Mainspring 3076M for Venus 60, Benrus L, MST 297, 306 - Alloy

WATCH-CRAFT Mainspring 3076W for Venus 60, Benrus L, MST 297, 306 caliber movements plus perhaps others, 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.
