The Seamaster line began in 1948. Today it includes the Diver 300M, the Planet Ocean and the Aqua Terra, many of them certified Master Chronometer, a standard tested by the Swiss federal institute METAS.
The Seamaster covers very different watches: compare sub-model, size and bezel type, and check that the helium escape valve on divers that have one is closed properly.
