The Seamaster 300 is a high precision instrument, self winding, shock protected and an anti magnetic watch. OMEGA guaranteed the watches water resistant to a depth of 200m. This watch was also used by divers of the British Royal Navy. It was the first watch to feature an unidirectional diving bezel.
