1675--5.1mil SN, "Mini" or "Radial" dial--posted by rolexonado

Note: "I bought [this GMT] from the original owner who wore it for a few months, thought it was too big and put in a safe where it remained until I purchased it in 2007.

Note the circular hour markers on the dial are smaller than you usually see. Also I thought the inserts with a blue tinted triangular hour marker at twelve oclock were service center replacements (the original being only in silver), but this one came from the factory with the blue tinted insert." - D.
