Crown screw-in is good. (0.7 turn of crown to unlock)

The case is Ref.1501 (confirmed between the lugs). The caseback is stamped “1500” with a date code “I.70,” suggesting it may have been replaced at some point.
This does not materially affect wearability or performance, and the core components remain consistent. That said, collectors who prioritize all-original caseback matching may take this into account.
