1967 - Rolex introduces the Sea-Dweller, a deeper-diving version of the Submariner. Its distinguishing feature is its helium valve, through which helium that has entered the watch case during time spent in a diving chamber can be released. The watch is produced at the request of the French company COMEX (Compagnie Maritime d’Expertise), which specializes in deep-diving equipment and services, chiefly for offshore oil and gas extraction. The watch is water-resistant to 610 meters. |

I think you either go with a regular Submariner, or a higher-spec non-Rolex. Too much rationalization-layering in this watch!
