and Garret,
i don´t like to make you unsure about your Royal Oak, but if it is possible, first contact Le Brassus to talk with them about your watch
and send them pictures - but also only the number from caseback must be enough , so that they can look at there "books".
I think it was, when leaving the factory, a 5402 - but not the steel version. From the number on the caseback I believe it was
a 5402 SA (stell/gold-version).
After there answer you have to decide what to do with the watch.
I only write this, because you payed for the watch and you have to pay a lot of money for the service.
regards
Stephan
