This ad is for a genuine 40MM Rolex Vintage Explorer II 16550 reference circa 1988. It is constructed of all stainless steel and is being sold on a 93150 oyster band with 501 end pieces. The serial number begins with an Rxxxxxxx. The original warranty papers and box have been misplaced. The dial is black with luminous plots and has patina. The sapphire crystal is in fair condition and has rough edges. The bezel also has scratches and dings on it and has been polished before. The flip lock band has a good amount of wear. This watch is running but with any vintage timepiece a service is recommended to ensure timekeeping and water-tightness. 3085 caliber movement is unique to this and GMT models. My price is semi-firm, don't hesitate to offer but don't bother low balling!
