Editor's Notes

A legend of oceanic proportions, the 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.

For an added layer of protection this timepiece has a helium escape valve (in a conical design) for when you’re underwater for that little bit longer, and with a 55 hour power reserve and durable rubber strap it's a reliable partner you can trust to keep up when you're venturing deep.
