One of the iconic diving watches of the 1960s is the Omega Seamaster 300. Making its debut in 1957, it wasn’t until the model reference ‘165.024’ came out in 1964, that the Seamaster 300 took on the fight with the Rolex Submariner. Both watches were of equal quality, and both received contracts from the MOD. Today a military issue Seamaster 300 is a much desired rarity, but the standard model also ranks high in the desirability stakes, and is one of those vintage diving watch must-haves.

Background to Omega Seamaster: The Omega Seamaster range made its debut in 1957, but it wasn’t until 1964, that the true Seamaster for diving purposes came out with the Seamaster 300. Bearing reference 165.024. The Seamaster 300 remained in production from 1964 until 1970. The Omega Seamaster 300 of the 1960s was so highly regarded as a professional diving watch that the British Ministry of defence contracted Omega to supply quantities of the ‘300’  for Royal Navy ‘special duty’ work.
