The Seamaster Professional Chrono Diver is a diver's chronograph by Omega.

This model, especially in the luxury version with the material combination of titanium/tantalum/rose gold, as flagship of a new series of striking, large-sized models, helped the world-famous brand Omega in the 1990s after a period of Sleeping Beauty to attain a furious comeback. The new watches not only gained attention by a convincing design, but also through maximum production quality and by a compelling price-performance ratio.

The current series bears, according to the maximum depth, the term Seamaster 300 M Chrono Diver.
