Comex (or Compagnie Maritime d’Expertises) is a French commercial diving company that issued Rolex dive watches to its fleet of deep-sea divers starting in the 1970s. Since divers at that time did not have all the computers and tech we have at our disposal today, their diving watches<\/a> were an integral part of their gear – and survival. On top of that, Comex needed watches that could plunge to extreme depths, handle pressurized chambers, and survive ensuing decompression periods. Enter the Sea-Dweller, which came fitted with a helium escape valve to greatly reduce the risk of damage to the watch during pressure changes. While Sea-Dweller watches were made available to the public to buy, there were some special editions reserved for Comex only.<\/p>\n

Rolex supplied several diving models to Comex over the decades, including both Submariner and Sea-Dweller watches. Rolex produced three different Comex Sea-Dweller<\/a> references: ref. 1665, ref. 16660, and ref. 16600. As expected, these now-discontinued Comex-branded Rolex tool watch references are highly collectible, prized for their rarity and history. Delve into the history, progression, and value of these fascinating diving watches with our ultimate guide to the Rolex Sea-Dweller COMEX watches.<\/p>\n
