OMEGA's Speedmaster Grey Side of the Moon "Meteorite" is an innovative addition to the Speedmaster collection. This timepiece is not only ready for adventure but is also stylish beyond compare. The grey ceramic case is complemented by 18K Sedna gold Moonwatch-style hands and an 18K Sedna gold bezel with a silicon nitride ring and brushed OMEGA Ceragold tachymeter scale. The Meteorite dial is made from a solid piece of ancient, extra-terrestrial stone that has been acid etched to reveal a unique pattern on each watch. Reminiscent of its legendary predecessors, the Speedmaster Grey Side of the Moon "Meteorite" has a 60-minute and 12-hour recorder at 3 o'clock and a small seconds sub-dial at 9 o'clock. OMEGA's Co-Axial calibre 9300 can be seen through the bevelled sapphire crystal caseback. It is presented on a grey leather strap with a titanium foldover clasp.
