Elgin Factory Mainspring for 18s No. 6079 (812) - Alloy

Elgin factory mainspring No. 6079 (812) for 18s movements, alloy, new in envelope. Has the typical Elgin DB&H end. See images for precise mainspring specifications. These were available in a couple of different strengths and those that I can supply can be found in the drop-down list. While not an easy number to find (maybe once a year or so I come across one) as this is the Elgin factory alloy versions of a #812. I probably don't have several of these but the one you get may still differ slightly from the images. I specialize is hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
