Elgin Factory Mainspring for 0s No. 6094 (825) - Alloy

Elgin factory mainspring Factory No. 6094 for 0s (& 1s) movements, alloy, new in envelope. When in steel this is a No. 825 and it has the typical Elgin DB&H end. These were made in several strengths and those that I can supply are shown in the drop-down list. I likely have several of these in each strength so the one you get may differ slightly from the images. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
