I'm not sure I'd really want to be invited onto the flight deck to inspect the Captain's ring?
Back on watches though, I always really fancied the Omega Speedmaster, but as it's double the cost of the Seamaster I couldn't justify it.
Still, it's cheaper than a Rolex, and far better built. Check out the "Torture tests" than NASA did on all the watches on the short list for the Space Programme:
