Important Notice regarding importation into the United States of Rolex watches
Sotheby's cannot arrange for the delivery of Rolex watches to the United States because U.S. laws restricts the import of Rolex watches. The buyer or a designated agent may collect the property in the country of sale."

COMEX (Compagnie Maritime d'Expertise) is a company specialised in underwater engineering and deep diving operations based in Marseille. In 1972, COMEX divers used the Rolex Sea-Dweller models in a world record-setting simulated dive which took them down to 2000 feet for one hour and a half. The watch performed so well that COMEX decided to use only Rolex diving watches and chronometers in their work.

In June 1972, the divers Alain Jourde and Claude Bourdier again went down to 2000 feet, in an experimentation which lasted 28 days. The divers remained at the lowest point, 2000 feet under sea level (610 meters), for 50 hours, a record-breaking feat, while wearing Rolex Sea-Dweller watches. At 2000 feet, there is a high percentage of helium gas, which can penetrate even a water-tight watch case. The gas cannot escape quickly enough upon resurfacing, and as the outside pressure decreases, the pressure remaining inside the watch due to the built-up gas can cause the watch to explode. The Rolex Sea-Dweller watch is fitted with a special helium valve, allowing the gas to escape quickly during decompression. The watches made by Rolex for the Comex company bear the word "Comex" on the dial.

According to our research, about 300 examples of the Sea-Dweller reference 1665 with gas escape valve were supplied from the late 1960's until the early 1980's to COMEX.
