Rolex Oyster Perpetual Ref.: 6619 18K Full Gold!

Very neat Rolex Oyster Perpetual 6619, 1966.The watch is made from 18K full of gold and measuring 26mm.The movement works fine and runs on time , but I don't have any maintenance history anymore.The only minus that's a small hairline on the dial between 10 and 11 hours marker.
