The Rolex 5513 Submariner existed in many forms from 1962 until about 1990. This is one of the earliest and rarest – with significant individual history. Note the early, pointed crown guards, the gilt text on the dial, the small silver underline and “double Swiss” anomaly at the bottom of the dial. This particular, early 1960s watch was provided for one of the Challengers in the Americas Cup sailing races. Rolex realised long ago that associating their watches with the very best in any field is a sound marketing tactic! Click on the pictures to see the very rare dial features in close-up.
