Seamaster 300 M Diver Chronometer is a dive watch by Omega.

Basic model of the Seamaster series.

There are two variants quite different in appearance: with black and blue dial, with or without colored (black/blue) bezel. The models are also equipped with two different self-winding movements: the Calibre Omega 2500 with co-axial escapement or its predecessor caliber Omega 1120.
