Seamaster Diver 300M

SEAMASTER

Precision at Every Level

OMEGA salutes the family launched 75 years ago

with an 11-watch collection, the Seamaster in Summer Blue, that celebrates water resistance 

To celebrate OMEGA’s oceangoing icon, the Swiss brand has produced a new collection with bold dials that include a striking tone reminiscent of a perfect day on a boundless sea.

The seven iconic models - eleven watches in all – track a trajectory from dressy to serious dive tech. Common to all is OMEGA's Summer Blue, used in greater or lesser degrees to reflect the water resistance of each Seamaster and relate its depth-defying credentials at a glance: Aqua Terra represents the sun-drenched surface, Ultra Deep the dark abyss. 

We invite you to explore this year’s special editions in depth.

A Brief History of the Seamaster

The story of the Seamaster begins 16 years before it was born, with the launch of the OMEGA “Marine” in 1932 - the world’s first divers’ watch available to civilian divers. This ingenious timepiece successfully tested at 73 metres below the surface of Lake Geneva, also proved water-resistant at a depth of 135 meters, when pressure-tested inside the Laboratory of Watchmaking Research in Neuchatel. This impressive start set the course for OMEGA’s rapid advancements in underwater design.

During the years of WWII, OMEGA delivered more than 110,000 watches for the pilots, navigators, and soldiers of Great Britain’s Ministry of Defence to support its Air Force and Navy pilots during service. That unprecedented experience allowed OMEGA to progress quickly in the fields of water resistance, anti-magnetism, and robustness, and create a series of watches that could withstand the harshest conditions.  Famously, the MoD gave each watch a W.W.W engraving on the caseback, which stood for “Waterproof Wrist Watch”.

Launched in 1948 to coincide with OMEGA’s 100th anniversary, the collection blended battle-proven technology with an elegant exterior to produce a watch for “town, sea and country.”

It soon became clear which word of the three would define its future. In the heady rock ‘n’ roll years, a decade of optimism and exploration, the Seamaster came into its own as the watch of choice for undersea adventurers. The starting point for this new trajectory was the Seamaster 300, released in 1957.

Wave after wave of extraordinary models followed. Each offering exciting new designs, innovative technologies, and even greater levels of water resistance. Along the way, the watch with the distinctive seahorse logo would play a key role in ocean exploration and conservation, as the timepiece of choice for the curious and the deeply concerned.  

Today, OMEGA is able to test every one of its water-resistant watches in a real underwater environment, thanks to the brand’s industry-leading facilities and the certification standards set by METAS (the Swiss Federal Institute of Metrology).

These timepieces, launched to mark the 75th anniversary of the Seamaster line, pay tribute to an extraordinary history of innovation, exploration, ocean-tested performance and design. 

Seamaster 300

Oceangoing professional

Launched in 1957 as part of OMEGA’s “professional” trilogy (along with the Speedmaster and Railmaster), the original Seamaster 300 offered wearers an easy-to-read display and exceptional water resistance, indicated by the "Naiad" star set within the logo on the crown. The new version continues that legacy with OMEGA’s Co-Axial Master Chronometer calibre 8912, certified at the industry’s highest level by the Swiss Federal Institute of Metrology (METAS).

This 41 mm Seamaster 300 has a symmetrical case and crown in polished and brushed stainless steel, with matching bracelet. As the name makes clear, this watch takes 300 metres in its stride and its varnished dial, in Summer Blue, reflects this deeper level of water resistance. In keeping with the colour code, OMEGA has filled the rhodium-plated hands, recessed hour markers, and open numerals with a unique light blue Super-LumiNova.
