Hello this is my first post in a forum! So anyway i recently bought this watch and i have searched everywhere for info on the movement. Its signed by concord and its a 248 F caliber but i believe concord did not make their own movements so i am trying to find what movement this really is. It looks like some felsa calibers from the 40s -50s but i dont know which one. I also know that the cxc on the balance cock means that its imported in the us by concord. Any information you might have will be very helpfull.
Ps: it also has a beautifulblued hairspring
