That’s an absolute beauty, you married well. Model reference number will be stamped inside the case back but I wouldn’t recommend you start trying to open unless you’ve got some experience with a case knife.
At some point it will be worth taking it for a service and asking the watchmaker to take note of the numbers.
I actually brought it to Omega on Regents street back when I was gifted it for a service, the reference number was printed on the assessment form: 688715/311036
