This classic matte dial 5513 from 1972 is in truely beautiful condition, look at those case chamfers! The case has clearly seen very little wear over the last 45 years and the matte charcoal dial is the same, with the Tritium lume aging to a warm golden yellow. The so-called "non-serif" dial matches the 3.8million serial number perfectly, and only the bezel insert and crown seem to have been updated. This is just an irresitable example of Rolex's most famous dive watch.
