My impression is that generally 218 dials are specific to particular cases. However there are some notable exceptions. The silver dial in the two watches on the left is to be found in all three of the cases pictured. These are 2975, 2984 and 2978.
It is more common to find that some individual cases may have a number of different dials. I think I have seen the same railroad approved dial in several different cases. Some comments please.
