Cosmograph 6234 questions

[chrisinwilson]

If anyone can help better identify this watch, I would greatly appreciate it. This is a Cosmograph that my father purchased used in 1963. He gave it to me about 20 years ago, and since recently learning about the collectibility of Cosmographs, we are both curious to learn more about the watch. The model number is 6234 and the serial number puts it at about 1961 manufacture date (though some dates say 1949 or '51 but I doubt it). However, the the dial, hands and bezel don't look anything like any other 6234s I can find online. Rather, it looks more like a 6239, with dial and bezel that appear to be from the early '70s. My dad doesn't recall ever having it serviced but there are enough inconsistencies between the features of this watch and descriptions of 6234s that I have to wonder. Thanks to anyone who might be able to shed some light on this or direct me to someone who can.

if it reads 6234 between the lugs then you've got a bit (actually a lot) of a mash up.

6234 case
6263 dial
6265 bezel

parts could be worth a bit if genuine

It is indeed 6234 between the lugs. Thanks for the additional reference numbers. Those parts appear to match up. Now to try to solve the mystery of how this mash-up was made...

Take the bracelet off and show some Macros of the print on the case, you don't have to show the entire serial number. Reason is to determine perhaps if case re engraved or case has some questions.
Besides the obvious question of why there is a later Oyster dial from a screw down Daytona and later than 63 imo. Lots of questions.

OK, a few more pics. Between the lugs on both sides. Serial number included. View of the case back and side view of the bezel for some added perspective.
