Just purchased an early 1940s Movado cal. 75, a little on the small side but it has a strong-looking military-type dial and is in good working condition. The dial, however -- and I presume the movement -- appears to be a little loose within the case. When I shake the watch gently I hear and feel some to-and-fro movement. And when I pull the crown out it is possible to gently shake the dial/movement within the case. I've not yet opened the screw back to investigate at this time.
Does anyone know what might be causing this? Do Movado's from the 40s period have case screws that might be loose? Or should there be some type of spacer between the dial and the bezel?
I am going to take the Movado to a watchmaker for servicing, but would appreciate any feedback if anyone has dealt with a similar issue.
