This is a stunning vintage GMT with dark nearly orange colored indices, just as I love it the most. Time has created this beautiful Patina and gave this timepiece a unique look and Aura. Exactly how I like it. This is a 5.5 Million Serial, dating the watch to around 1978. It is amazing how 35 years left so much Patina? I wonder if it is the result of the sun, or humidity, or how some watches have all this Patina and others don’t?
