Update- my watchmaker says the crown and case tube appear to be unused. Only thing the crown will need is a new gasket Needless to say, I'm psyched to have picked up a basically NOS crown and casetube (among other things including a mainspring which wasn't included in the picture) for about 20% of what they'd cost me new!
Freddy - the leather book is actually the owners manual for a model 1024 rolex- including the owners manual, warranty, and, amazingly, the Chronometer certificate made out for Rolex #2,941,997. If, on the off-chance, anyone has that Rolex- I've got your original papers!!
