There are quite a few Rolexes that are considered to be "museum-quality" and one of these models is definitely the Rolex Experimental Deep Sea Special. There are seven known prototypes that were built between 1953 and 1960 and only three have been identified. This November, the Deep Sea Special N°1 will go up for sale with a bracelet and movement that are in perfect working condition. The watch was also attached to the hull of Auguste Piccard's bathyscaphe Trieste research vessel, where it dove into the Mediterranean and reached a depth of 3,150 meters/10334 ft.
The Rolex Experimental Deep Sea Special N°1 will be going up for sale on November 8th at the Christie's Rare Watch Auction at the Hotel Four Seasons Le Bergues in Geneva, Switzerland.
