Ref. 6536 is one of the rarest Submariner models, made only for one year, 1955. It features the “Submariner” name introduced in late 1954 and a five-digit serial number. It is thought that only up to 100 examples were manufactured in total. The reference 6536 came after the reference 6204 and around the same time as the 6538 with the bigger crown. Both models were fitted with the caliber 1030 movement with bidirectional rotor which improved the efficiency of the automatic winding.

The early history of the Rolex Submariner is perhaps one of the most interesting amongst all vintage Rolex watches. These models were made in exceedingly small numbers and during a very short period only, changing reference as each development and update was introduced.

The Submariner has left a legacy of a rich variety spread over several early period, references all with subtle differences in design and construction. These Submariners, made in such small numbers and even fewer surviving, are now amongst the most desirable to collectors.

The present lot is preserved in extraordinary original condition, with a crisp and razor sharp case, near flawless "no hash" bezel insert as well as a beautiful and evenly aged dial. Undoubtedly, one of the nicest 6536 to come to market in recent years, this watch will be the crown jewel of any dive watch collection.
