This Rolex GMT-Master was produced in 1990. The watch is in excellent condition with a nice thick oyster case and thick lugs. This reference was the first GMT Master and is equipped with a black glossy dial, applied white gold hour markers and a sapphire crystal. It features original tritium. The pepsi bezel is in mint condition, like the rest of the watch. The spring bar holes are clean and crisp and not elongated. The original 78860 solid oyster bracelet with 501B endlinks shows hardly any stretch. The caliber 3175 movement is running accurate and was serviced.
