Omega Seamaster - The History
From Chronopedia
Brief History of the Omega Seamaster=
The Seamaster is the longest running product line still produced by Omega. It was introduced in 1948, and was loosely based upon designs made for the British Royal Navy towards the end of World War II. The original Seamaster's key feature was an O-ring gasket used to provide its waterproof seal. This design had been developed for use in submarines during the war, and turned out to also be useful for watches, where it made them much less vulnerable to temperature and pressure changes than earlier (lead or shellac) based gasket designs. The Omega Seamaster first made a diving record in 1955, when diver Gordon McLean reached a depth of 62.5 meters (205 ft) in Australia.
