Marco Mainspring #3272 for Venus Caliber 170 Chronograph - Steel

Marco steel mainspring #3272 for Venus caliber 170 Chronograph and perhaps others. The V170 was a 12½ ligne movement produced between 1940 and 1952 and was the basis for a whole plethora of Chronographs of the day. I likely have several of these so the one you get may differ slightly from the images. See images for precise mainspring specifications. 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.
