Happy to know that this 16750 sings to you, my friend, as this is, IMO, a very interesting watch...
With Rolex, the problem is that if you only buy one watch, you're suspected to be a show off guy...
BUT If you don't have a Rolex in your collection, I think that something will miss, IMO...
So, yes, a nice Vintage Sub, and a Vintage GMT, with a great patina, is something very exciting, and appealing, Emilio...
The question is not IF but WHEN will you get your first one...LOL
Best.
