Question is in reference to replacement of movement from a functional watch. I am attempting to use old the gold case (pictured) due to its sentimental value. I had someone open it up to tell me that it is a REF 14701 4 SC? Can have a professional watch repair shop replace only the movement from a functional watch (REF. 14701 SC-61)? I would think this would be possible but I am not sure if the REF #'s match or if there are any differences in the case. Thank you!
