A variety of bracelet and strap options are available, and since the 42mm case has a standard 20mm lug spacing, swapping styles is easy. The 42mm case is most common, though the range includes models as small as 36mm and as large as 46mm. Over the years, Omega has offered a variety of special edition Seamasters, many of which feature innovative and unusual case designs and shapes, carrying the space-age flair of the late '60s and early '70s. Stainless steel remains the most popular and collectible metal, while titanium and ceramic versions are widely available on the new and pre-owned market.

Seamasters have been produced with and without a date window, featuring a variety of complications in several case materials. A naiad crown with a spring-loaded seal that tightens as depth increases.Seamasters generally have a low profile that makes them easy to wear under shirt sleeves and a jacket. All Seamasters are built with a rubber gasket which, depending on model, ensures water resistance at depths up to 1,200 meters. The Seamaster family includes hundreds of variations with automatic and quartz movements. Since the first 300, the Seamaster has held the position of a tool watch that naturally doubles as an all-around, everyday timepiece. Ironically, the 300 was only certified waterproof to a depth of 200 meters, not 300 as the name implies. The 300 debuted in 1957, along with Omega’s legendary Speedmaster line and the Railmaster. This innovation pointed Omega in the direction of building the Seamaster 300, a true dive watch, which was squarely designed to compete with the Rolex Submariner. Early Seamasters were marketed as dress watches and advertised as having “more ruggedness built into the Seamaster than you are ever likely to call for.”īy incorporating a rubber gasket to seal the case and crown, even the earliest Seamasters were certified for water resistance to 60 meters. It was inspired by the watches Omega produced for the British Royal Air Force during World War II. First introduced in 1948 to celebrate Omega’s centennial, the Omega Seamaster watch has been in production longer than any other Omega collection.
