From Omega:


Saluting OMEGA’s space legacy and capturing a NASA astronauts first impressions of the Moon, the Speedmaster “Grey Side of the Moon” is yet another iconic timepiece crafted using the most innovative techniques.

Inspired by the lunar dust that preserved the human footprints on the Moon, this watch is crafted from white ceramic innovatively transformed to a metallic grey. It recalls the astronaut Jim Lovell’s words during the Apollo 8’s lunar orbit: “The Moon is essentially grey.”

OMEGA’s Speedmaster “Grey Side of the Moon” is an innovative addition to the Speedmaster collection. With its grey ceramic case, sand-blasted platinum 950 dial, Moonwatch-style hands, ceramic bezel and tachymetric scale in white Super-LumiNova, this timepiece is not only ready for adventure but is stylish beyond compare.


Reminiscent of its legendary predecessors, the Speedmaster “Grey Side of the Moon” 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.
