I have several Vintage GMTs, but with the crownguards, pointed or not, gilt, or not, chapter ring or not.
The epitome of the Rolex GMT is, to me, the first one, this reference, the 6542.
Now, to find one which will sing to you is another problem, indeed.
I'm sure that one day, you'll say " Wow, that's mine ".
And that you'll share it with us!
Waiting for this moment...
Best,
Nicolas.
