For sale is a nice example of a late 1970's Rolex GMT 1675. The watch is in excellent overall condition. Box, Booklets and hang tag pictured are included with the sale. I do not have the papers. 

The 5.1 million case has been previously polished but still looks great. All case engravings are legible with the naked eye. 
The bracelet is a 78360 with 580 end links and fits a 7.5 inch wrist. 
The insert is free of an marks with perfect "PEPSI" color. Crystal is free on any major blemishes. 
The dial is a matte service with hands that match perfectly. They do glow when charged with light. 
Watch runs well, keeps time but I don't know any service history.
