That is a very nice watch, congrats! And good luck with the academic part too!

No one has a crystal ball, but I would wager that in 12 months, the situation will be very different. Stick the money you planned to spend on the watch in a fixed deposit or some other absolutely safe investment, and in 12 months you might have a chance to buy the watch and use the interest for a beer or 2.  Or offset the price increase at the AD if that happens ...

Rolex OP39 black dial or Explorer 39mm 214270?

Wait a while more and I think you’ll see them at 6k. 

Yes, I am aware that Omega makes better watches at that price. I just wish they could make them less than 12mm thick. 

I’m in my late 40s.
