A legend of oceanic proportions, this OMEGA Seamaster 300 of today is leaps and bounds from the original. Although it may have been born in 1957, the Seamaster 300 has seen a number of enhancements over the years. And today? This clean, crisp and Master certified collection still maintains its vintage charm.

300m of water resistance is just the beginning with this outstanding diver’s tool. Handsomely crafted with a ceramic bezel, stainless steel case, and bracelet, it's a diver's dream and a waterproof wonder.
