Bought this on a bit of a whim off the Bay and can't wait for it to arrive.....to see if there actually is a movement inside. Assuming there is, it will need - and get - mucho TLC.
Probably not a 30mm movement inside that one. More likely a cal. 26.5. Nothing wrong with that one. Just as high grade as the 30's, just a little bit smaller.
With any luck, just Polywatch the crystal and wipe down the case. Get the movement serviced and you should be good to go. Everything else looks original.
Congratulation on a nice vintage purchase.

Yann, don´t be so shy - these are really beautiful "originals"
BTW what Ref. is this? Is it CK 2192 ?
Is it pressure shut or with a screw in back?
