Hi All I believe this is a 1949 Oyster Perpetual Bubble Back but not sure of the model number or the value? Sadly I have no other details.
Without pictures of the case back (inside and outside) and the movement any information would be total speculation. gatorcpa
AML looks wrong. Dial looks off center. Condition does not match age, Bezel does match any others on a google search. There are a lot of variations on these and google shows some fakes or very bad redials out there. These will take some serious research to be able to nail down price. Honestly this looks like a fake of Ryan Goslings watch.
Bezel is rotated to the left (counterclockwise). Something is amiss with the crown and stem?. Could be the pic's, but the watch looks... contrived?.
Lume dot at the 12 position is off. Crown close up to speak to @kingsrider observation of the crown/stem. HQ dial shots would give the experts a better opportunity for finding out what you have my friend! Happy 2017! Thomas
