About the model
In 1957, Omega introduced a trilogy of professional models: Speedmaster, Railmaster and Seamaster 300.
The Seamaster 300 is a diver’s watch allowing a depth of at least 200 meters. The first version, reference CK 2913, was produced from 1957 to 1961, replaced by CK 14755 with the new caliber 552. The referencing system was changed in 1962 and CK 14755 was renamed ST 165.014 and produced until 1967. In 1963, a new dial with bigger indexes was introduced, but that year also marked the birth of a new asymmetrical case line, to better integrate the crown: this is reference ST 165.024, produced until 1970/1971. In 1968, it was joined by a version with date (reference ST 166.024).
Although the Seamaster 300 was developed and marketed for a professional use (e.g. by COMEX or British Army), its sharp and simple design, as well as its perfect dimensions / proportions (in particular reference ST 165.024) has attracted a much wider audience around the world and its popularity is still growing.
