Waltham Factory Mainspring for 12s Colonial R "C" No. 2252 - Steel

Waltham Factory Mainspring for 12s Colonial R "C" Movements, # 2252, steel, new in envelope. Has a DB&H end which is unique among Colonial models. These came in several different strengths and those that I have available should be in the drop-down list. I do likely have several of these in each strength so the one you get may differ slightly from the images. See image for further details. 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.
