Notes
Production of this reference began in 1970. While other companies used helium escape valves to solve the problem of the crystal ?popping? during decompression due to helium absorption, Omega created an impenetrable case with a vacuum within it such that it would take 1000 years - at normal atmospheric pressure - for air to again penetrate the case. One of these watches, tested in a pressure chamber, continued to function to 137 atm, the equivalent of 1370 meters of depth.
