Out of the Deep Blue: The Rolex Experimental Deep Sea Special N°1

Rolex Experimental Deep Sea Special N°1

This watch is THE FIRST AND ONLY Rolex Deep Sea Special that made the first dive attached to Auguste Piccard’s bathyscaphe Trieste in 1953. On this watch that made history, the case, the original movement and the bracelet are in perfect working condition.

This is the N°1 – A watch that made history on 30 September 1953, and will make it once again on 8 November 2021.

Developed as a prototype for perfecting the Rolex diving watch concept, this Rolex Deep Sea Special N°1 was attached to the hull of Auguste Piccard’s bathyscaphe Trieste for the inaugural deep-sea trial to a depth of 3,150 meters in the Mediterranean on 30 September 1953.

This watch then served as the proving ground for the Rolex Deep Sea Special N°3 that would reach 10,908 meters in the Mariana Trench with the Trieste on 23 January 1960 and is today on display at the Smithsonian Institution in Washington DC.

Rolex Experimental Deep Sea Special N°1

The Christie’s Rare Watches Auction on 8 November 2021 at the Hotel Four Seasons Les Bergues in Geneva promises to be a landmark event. Among the treasures to come up for sale, an extraordinary and rare timepiece, not just a witness but a participant in an event that to this day epitomizes the human spirit of adventure – and the commitment to the Excellent and the Exceptional that Rolex has always stood for. The Rolex Experimental Deep Sea Special N°1 entrusted to Christie’s only strengthens the enduring fascination of a watch brand that, always true to its purpose, not only defines time but transcends it.

Not one of the watches that could, but the only one that did.

“For a holy grail watch such as this prototype Deep Sea Special Number 1 to become available is a dream come true in so many ways and for so many watch lovers, Rolex fans and connoisseurs around the world.”

“THIS WATCH is the ultimate incarnation of the Oyster case design which from then on defined the Rolex watches and the brand,” says Rémi Guillemin, Head of Watches, Christie’s Geneva.




The rarest among the rare Rolexes – the Deep Sea Special Prototypes from 1953 to 1960

It is said seven prototypes were built between 1953 and 1960. This much is absolutely certain, only three have so far been identified: the Deep Sea Special N°1 with a ‘low glass’ (made from Plexiglas) that accompanied Trieste on its first deep-sea trial down to 3,150 meters (10,245 feet) off the island of Ponza in 1953; the Deep Sea Special N°3 with a ‘high glass’ (a taller and thicker crystal, also of Plexiglas, one of the invaluable learnings from N°1) that made the trip down to the bottom of the Mariana Trench (10,916 meters, 35,814 feet) in 1960 and is today out of reach but on display, together with the Trieste, at the Smithsonian Institute in Washington DC; and Deep Sea Special N°5, also a ‘high glass’ version, which presumably served as a proving ground for further extreme testing in the period leading up to 1960, and was offered at auction by Christie’s in 2000.

In the early to mid-1960s, to celebrate the dive down to the world’s deepest place and after the unexpected worldwide success and enthusiasm that this event generated, Rolex produced about three dozen display models to share their exploit and know-how with the public. In 2009, Number 31 of this commercial/promotional series was sold by Christie’s.
