So, here's the GMT that arrived yesterday, bought from a guy in New York.
This shot's as it was out of the packaging...
As you can see the glass was pretty scuffed up taking the shine off the dial.
Removing the bezel revealed years of gunge and dirt etc.
Removed the pushers which were pretty bunged up too.
After a bl**dy good clean, popped the movement back in.
And, really pleased with the results :-)
