This Rolex GMT-Master was produced in 1991. The watch is in good 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 black bezel insert shows some signs of wear, giving the watch some character. The spring bar holes are clean and crisp and not elongated. The original 78860 solid oyster bracelet with 501B endlinks shows some signs of stretch. The movement is running accurate and was checked by our watchmaker.
