Quick Fit Mainspring #1922 for LeCoultre Caliber 449, 450, 468A - Steel

Quick Fit steel mainspring #1922 for LeCoultre caliber 449, 450, 468A and many others in this family (470, 478, 479, etc.). These are 12¾ ligne movements produced in 1940's and 1950's and are commonly found on Royal Air Force Military watches, among other watches - including the 494 which is often seen as a calendar and moonphase! 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.
