"It was the adventures and the accomplishments of the Apollo 8 astronauts that inspired the all-black, ceramic Speedmaster Dark Side of the Moon, but it is the mystique of the Earth’s nightlight and its ever-changing yet constant presence that has spurred the creation of the Speedmaster Dark Side of the Moon ""Sedna Black"". This 44.25 mm model has a completely brushed black ceramic case with an 18K Sedna™ gold bezel ring which matches the 18 Sedna™ gold applied indexes and hands. The marks on the matt grey dial have been created using laser ablation. The ""Sedna Black"" is presented on a black leather strap with a brushed ceramic foldover clasp. At its heart is the OMEGA Co-Axial calibre 9300."
