Note that more than one movement from Omega was made as a 19L, with this mainspring being the larger version with a tongue end so please see images for precise mainspring specifications and make sure this is the one you need. I specialize is 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.
