Just to inform you here properly, i've found another puzzle in the DeepSea Saga as I just received a email from the Curator of Maritime History, National Museum of American History, Smithsonian Institution. My logic question for my research to Mr. Paul F. Johnston was, which number had been engraved on the case back of their White dialed Rolex DeepSea Special Prototype version thats on display in Washington and we see below.

"Dear Mr. Stahl,

The engraving on the back of our Rolex:

ROLEX OYSTER / NO. 3 / DEEP SEA SPECIAL

I'd be grateful for any information you could provide as to the significance of this, and how it fits into the bigger picture of deep sea Rolex watches.

Best wishes,

Paul F. Johnston, Ph.D. Curator of Maritime History, National Museum of American History, Smithsonian Institution. "


I explained that their Rolex DDS is a Prototype, much more rare & important in general then the later, after 1960, made Display version of the DSS. Besides that, we only know of 3 early prototypes of which the Smithsonian is the only one having the experimental white dial.
