Omega Seamaster 120 History and Defining Characteristics<\/strong><\/h2>\n\n\n\n

The Omega Seamaster range was launched by the vaunted brand in 1957. It coincided with the simultaneous releases of the Speedmaster and Railmaster lines and marked the beginning of Omega\u2019s foray into the world of dedicated dive watches<\/a>.<\/p>\n\n\n\n

The original Seamaster 300 had a depth rating of 200 meters. At the time, 200 meters of water resistance was more than enough for the casual diver, let alone the average suburbanite who was more likely to wade in the local swimming pool than the ocean.<\/p>\n\n\n\n

In 1966, Omega launched the Seamaster<\/a> 120, a smaller version of the Seamaster 300, with a depth rating of 60 meters. The idea behind the Seamaster 120 was to offer a more affordable version of the Seamaster to a customer base that was more likely to wear it while driving their Barracuda than diving next to one.<\/p>\n\n\n\n

While, in 1966, the Seamaster 300 had a case size of 42mm, the Seamaster 120 came in at a more diminutive 37mm, making it a better fit for the office or a backyard barbecue. There was also a 31mm women-sized case available.<\/p>\n\n\n\n

Aside from the case size being different than its forebearer, the Seamaster 120 also had a slightly different case shape. Omega utilized a cushion-styled tonneau-shaped case, which offered a slightly more elegant wear than the tool-styled case of the Seamaster 300.<\/p>\n\n\n\n

Overall, the Seamaster 120 was a popular alternative to the Seamaster 300, which is why you can still find several vintage pieces available for sale on the secondary market. The following are the most common references and basic price ranges for the Seamaster 120.<\/p>\n\n\n\n
