Watch Description
M4 on movement, M2 on caseback, superimposed with M7. As can be seen from the patent diagram, this type of waterproof case was submitted for patent in 1954, but not granted until five years later. https://www.google.co.uk/patents/US2871654?dq=US2871654&hl=en&sa=X&ei=e25MVbnSI8bl7gaFoYHgCg&ved=0CCAQ6AEwAA

Bob, are you saying that the case back is double stamped, M7 over M2?

Yep, looks like it. See the scratches where some doofus tried to pry the back off? Still need a female stem. Come on back, JP!
