The newly unveiled OMEGA Seamaster Diver 300m Chronograph numbered version combines gold, titanium and tantalum. The three different metal textures complement each other and are eye-catching.
This watch uses tantalum metal, which first appeared in the Omega Seamaster series in 1993, and combines grade 2 titanium and 18K Sedna™ gold to show an extremely refined layering between the bezel, crown and bracelet. The unique blue-gray color of tantalum cleverly sets off the luxurious brilliance of precious metals.
The 18K Sedna™ gold bezel ring is attached with a laser-ablated diving scale, and the polished blue zirconium dioxide ceramic dial has a laser-engraved wave pattern, a date window at 6 o’clock, and an 18K Sedna™ gold counter ring. There is an 18K Sedna™ gold plate engraved with the watch’s unique code on the side of the case. The transparent case back shows the laser-engraved and white-painted Omega Seahorse pattern on the sapphire crystal glass, as well as the Omega Co-Axial Master Chronometer 9900 movement certified by the Swiss Federal Institute of Metrology (METAS).
For ocean explorers, each bracelet contains Omega’s patented toothed bar extension folding clasp, and an additional extension bracelet for diving is provided. And in response to the deep waterproof characteristics of the Seamaster Diver 300m watch, the watch box is specially inspired by the classic polygonal design of the watch in the form of a waterproof chamber.
What are the characteristics of gold, titanium and tantalum?
Tantalum metal
Tantalum is a bright blue-gray metal that is rarer than gold, harder than steel, and highly resistant to corrosion. It will not absorb acids even when immersed in water. This acid resistance makes tantalum stronger. Its inertness makes it a valuable alternative to platinum. Tantalum is dark in color, dense, flexible, and has excellent thermal and electrical conductivity, but it is very difficult to process, so it is rarely used in the watch industry.
18K Sedna™ Gold
In its constant quest to improve its products, OMEGA wanted to find a new rose/red 18K gold alloy that would resist fading better than the industry standard 18K rose gold. In 2013, OMEGA achieved this goal. This material, called 18K Sedna™ gold, has a beautiful red color and excellent resistance to fading. An alloy that combines gold, copper for color and palladium for stability, OMEGA’s exclusive rose gold has a unique red hue that is warm and long-lasting. This unique 18K gold is named after the orbiting dwarf planet Sedna, one of the reddest planets in the solar system.
Secondary Titanium
Titanium was discovered as early as 1794, but its industrial processing only began in 1939. Although titanium is a fairly common mineral, it is still an expensive metal because of the difficulty of processing titanium from other terrestrial materials. Titanium alloys are lightweight, have excellent corrosion resistance and biological inertness, and can withstand extreme temperatures. Grade 2 titanium can be heat treated, which means that its toughness can be increased through a heat treatment process, making it the perfect material for moving parts in harsh environments. Omega has used grade 2 titanium many times in its watchmaking history, such as the Speedmaster X33 watch and the previous version of the Seamaster Diver 300M watch.
