THE Iconic watch and movement. Nice!
I have an Oris divers watch. I also have Rolex and Omega, but I think for biggest bang for your buck, Oris wins.
I will also add that the Rolex is a vintage model, circa 1971. It's 43 years old and is as accurate today as my modern Rolex. It is 40mm in diameter; the Speedy is 42mm.
Taken with my Panasonic LX7. Incidentally, for those not familiar with GMT watches, Rolex was the first to add a fourth hand (arrowhead), in conjunction with the rotating 24 hour bezel, to allow setting a second timezone.
