Originally launched in 1967, the Sea-Dweller was the result of a historic collaboration between Rolex and French deep sea dive company COMEX in the early 1960’s to test and develop a watch that could withstand ever increasing working depths and remain intact during ascent and decompression. The primary issue with dive watches at extreme depths had been the buildup of helium gas within the case which would increase during decompression to the point of watch failure. The solution to this problem, and born of this collaboration, was the creation of a helium escape valve which allows the helium gas to leave the case through the valve instead of blowing out the watch crystal. Found today in a number of Rolex modified reference 5513 followed by reference 5514, which was the first reference manufactured by Rolex with the escape valve. Reference 5514 was specifically designed and manufactured for COMEX and not commercially available, though because of the success of the technology the Sea-Dweller was launched commercially in 1967.

The present lot, bearing serial 6’057’725 and dating from 1979 is an extraordinary early example of what is known by collectors as the “Great White”. So named because the brand had just transition from red printing of “Sea-Dweller” and the depth rating below it, to all white printing in 1978. Consigned by the family of the original owner and complete with its inner and outer boxes, hand executed ‘garantie’ as well as hangtag bearing the serial number, this is truly one of the nicest and most complete “Great White” Sea-Dwellers to come to market in recent years. With an exceptionally sharp case showing all its original factory finishing, this watch has an absolutely flawless MK1 dial with lume which has developed a wonderful creamy patina, and hands which are perfectly harmonious and matching.

Full set vintage Rolex sport watches of this quality and provenance are rarely seen anymore, making this original family “Great White” an incredible rarity.
