PM Merelloy Mainspring M260 - Hamilton 16s movements No. 534 - Alloy

PM Merelloy Mainspring M260 for Hamilton 16s movements, Factory No. 534, alloy, new in envelope. See images for additional information and note this is equivalent to a HR SA208. 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.
