Following the phases of the moon and taking the brand's spirit of exploration one step further, this Omega Speedmaster Moonphase 18ct Sedna gold co-axial watch celebrates the history of the Speedmaster - the first watch ever to be worn on the lunar surface. This iconic and unique watch is presented on a brown leather strap and features a 44.25mm 18ct Sedna gold case with a brown ceramic bezel ring and tachymeter scale. Scratch-resistant sapphire crystal protects the brown sun-brushed dial that's enhanced by diamond polished 18ct Sedna gold baton hour markers and hands, coated in Super-LumiNova for extra brightness in dark conditions, two chronograph sub dials and the accurate moonphase indication at 6 o'clock with a metallic crystal disc, microstructured to obtain a high resolution image of the moon that's as detailed as a NASA photograph. If you look close enough, you will see an added astronaut's footprint on the moon. Water resistant to 100m, this beautifully made watch is powered by a self-winding chronograph movement with column wheel mechanism and Co-Axial escapement, resistant to magnetic fields reaching 15,000 gauss and a power reserve of 60 hours. This stunning watch also celebrates another pioneering moment: Omega's exacting new standard of testing by METAS, to ensure the highest quality of watch engineering. O30423445213001
