Omega has used the Seamaster name since 1948, when it launched as a water-resistant dress watch. The dive watches arrived with the Seamaster 300 in 1957, and the family now runs from the Aqua Terra to the Planet Ocean. The Diver 300M of 1993 set the template the line is still known for: wave-pattern dial, skeleton hands, helium escape valve on the case side. Planet Ocean sits above it at 600m rather than 300m, with more wrist presence.
How you know it
