Ivory Patina - this very crisp and mint example of a Rolex Submariner 1680 has it in it. The condition of this watch deserves a "wow" in every aspect.The case is fat and sharp with well defined and beautifully beveled lugs. The area between the lugs is unmolested and bears fully intact numbers. The almost flawless MK1 dial is retained very well. The Tritium has consistently aged to a Ivory color and is matching with the hands. The original and matching Oyster bracelet is in equally mint condition and only shows very little wear from age. Last but not least the bezel holds a Super Fat Font insert which complements the aesthetics of the dial. This 1680 will make you hold your breath, its one of the nicest we had.
