Marco TIME Mainspring #3329 for Imhof caliber 447 Travel Clock - Steel

Marco Mainspring No. 3329 for Imhof caliber 447 Travel Clocks, steel, new in envelope. This is the TIME side mainspring, the alarm side is quite different, see images for precise mainspring specifications. These are likely covered in some very old grease and will need to be cleaned thoroughly before being used. I likely have several of these so the one you get may differ slightly from the images. I specialize is hard to find watch parts and all parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
