This 1977 Rolex Oyster Perpetual Date Submariner ref. 1680 is highly sought after. The original and sought-after matte-black dial is as clean as they come, with the original matching hands. The bubbledate crystal is pristine and has been polished. The date appears clouded in the photos, but not anymore. This case is scratchless and the 5.2 million serial number is crystal clear. We just had our Rolex-approved watchmaker dismantle and clean this fine Submariner and it is accurate.
