Omega - Seamaster Diver 300M Chronograph in Titanium, Tantalum and Sedna Gold

The new Omega Seamaster Diver 300M Chronograph 44 mm offers a striking look, obtained by combining titanium, tantalum and Sedna gold. Price and specs.

With its blue/grey tones creating a contrast with the warm hue of Sedna gold, the latest variation of the Omega Seamaster Diver 300M Chronograph 44 mm offers a striking look, obtained by combining titanium, tantalum and Omega's proprietary rose gold alloy. 

Grade 2 titanium is complemented by Sedna gold, used for the bezel ring featuring a laser-ablated diving scale, the crowns, the chronograph push buttons and the middle links of the bracelet, and tantalum, found on the base of the bezel and the inner part of the bracelet's links.

Each of these metals offers unique properties. 

Titanium alloys are light, extraordinarily corrosion resistant, biochemically inert and able to withstand extreme temperatures. Grade 2 titanium is in fact heat-treatable, which means it gains additional strength via the heat-treatment process, making it perfect for moving parts in challenging environments.

Rarer than gold, harder than steel, and highly corrosion-resistant, tantalum is an alternative to platinum  for its inertness. Thanks to its high density, it is extremely resistant to acids. On the other hand, it is particularly difficult to work with. 

Sedna gold is an alloy blended from gold (at least 75%), copper for colour and palladium for stability. The result is a unique reddish tone that is warm and particularly long lasting. The unique 18K gold takes its name from Sedna, an orbiting dwarf planet described as one of the reddest in the solar system.

The three metals used for case and bracelet are matched to a polished blue ceramic [ZrO2] dial sporting laser-engraved waves, a date window at 6 o’clock, and subdial rings with touches of Sedna gold. On the side of the case is a Sedna gold plate engraved with the watch’s individual number.

Embellished by a laser-engraved and white lacquered Omega Seahorse, the sapphire crystal of the caseback reveals the Co- Axial Master Chronometer Calibre 9900, certified by the Swiss Federal Institute of Metrology (METAS). Beating at 28,800 vibrations per hours, this self-winding chronograph movement with column wheel mechanism and Co-Axial escapement offers a power reserve of 60 hours. 

The bracelet includes Omega’s patented extensible foldover rack-and-pusher with an extra diver extension.

Water-resistant up to 30 bar (300 m / 1000 ft.), the Omega Seamaster Diver 300M Chronograph in Titanium, Tantalum and Sedna Gold ref. 210.60.44.51.03.001 is offered inside a special presentation box in the style of a water-resistant chamber and has a price of Euro 18,500. omegawatches.com
