BOREL Mainspring 6026-Q for Lang 1036, 1136, MST 371, 372, Oris 450 to 453 - Alloy

BOREL Mainspring 6026-Q for Langendorf 1036, 1136, MST 371, 372, Oris 450, 451, 452, 453 & Reconvelier 120 caliber movements plus perhaps similar ébauche watches, white alloy. See images for precise characteristics. 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.
