The Seamaster was first introduced in 1948 to celebrate Omega’s 100th Anniversary, it was an immediate success and is Omega’s longest-running model. Based on the waterproof designs used during World War 2, it was improved upon with the addition of an “O” ring gasket which improved its water resistance. Omega’s first diving record came in 1955 when diver Gordon McLean reached a depth of 62.5 metres (205 ft) in Australia. The engineers were so confident of the durability that they strapped one to the outside of an aircraft that flew over the North Pole in 1956.

Here we have a 1964 Omega Seamaster 600 135.011 with a 34mm stainless steel case, the angled lugs have a lug-to-lug length of 40mm and a case thickness of 8.5mm ensuring a comfortable fit on your wrist.
