OMEGA first created the Seamaster to commemorate the brand's 100th anniversary. As sports watches grew in popularity in the 1950s and 60s, it quickly became one of their most in-demand models among amateur and professional divers. In the 1990s the Seamaster’s popularity skyrocketed after it became the official watch of James Bond. To this day, the Seamaster is one of OMEGA's longest continuously manufactured and highly sought after models. Buying an OMEGA Seamaster watch is an excellent way to start or grow your collection. Here, we have a wide selection of exceptional used OMEGA Seamaster watches for sale, including variations like the Aqua Terra and the Planet Ocean.
