E serial ca. 1990...love the independent hour hand making the 16710 a "truer" GMT but I miss my old 16750 I had to sell to keep body and soul together. The five digit serial GMT Masters tick all the right boxes. Hunting down a faded Pepsi insert to go with the Coca Cola variant..
Not a 1675 but to me it's the business , bought new by me in July 99 & is the best of all the Rolex GMT masters in my opinion. My Rolex 16700 GMT Master 16700 A serial below .
