I should've added, too: congratulations--that's a really lovely gift.
As gets written to everyone here who gets a watch like this: if you plan on wearing it, you should get it serviced (not sure what you mean by "manual wind dial is loose"--do you mean the crown?), but not by Omega itself. Omega will try to make it look brand new, meaning polishing it and replacing parts. Your watch, I suspect, hasn't been messed with and is entirely original. If you're interested in recommendations, you might post generally where you are, and folks can chime in about reputable watchmakers who could service the watch.
Regardless: congrats again. That's one of the most fun watches to wear that I know of.
