OMEGA Seamaster Diver 300M Chronograph Titanium Tantalum Sedna™ Gold

As the name suggests, this new Seamaster dive watch combines three innovative materials known for their exceptional qualities: Titanium, Tantalum and Sedna™ Gold.

Tantalum is a lustrous blue-grey metal that is more rare than gold, harder than steel, and highly corrosion-resistant. Titanium is light, extraordinarily corrosion resistant, biochemically inert and able to withstand extreme temperatures. Sedna™ gold, which is OMEGA’s own rose gold alloy, which combines gold (at least 75%), copper for colour and palladium for stability.

Omega made its first tantalum Seamaster watch in 1993. This extremely uncommon and arduous material is rarely used in watch making. With this new Seamaster Chronograph, Omega is bringing back this distinctive blue-grey material to the limelight.

Omega has been using grade 2 titanium for manufacturing some exceptional sports watches such as the Speedmaster X33 and earlier editions of the Seamaster Diver 300M. In 2013, OMEGA introduced 18 Sedna™ gold, a new rose/red 18K gold alloy that is more resistant to discoloration than the standard 18K red gold. This new gold alloy’s unique reddish tone is warm and particularly long lasting.
