Footnotes:
The Submariner Ref.6536-1 is one of the earlier Submariner references that was only produced for a few years whilst Rolex were perfecting the model. It went through numerous alterations before arriving at the noteworthy references 5512 and 5513, produced from 1959 and 1962 respectively. The 6536-1 has a thinner case than other models of the period but showcases the classic features of the early models.

The popularity of pre-crown guard Submariners has surged in recent years, thanks in no small part to their presence in the James Bond favourites 'Dr. No' and 'Goldfinger'.
