Fastened with a grey leather strap, the 44.25mm grey ceramic case features brushed and polished surfaces and is finished with a grey ceramic bezel with an engraved tachymeter scale made using laser technology and illuminates with white Super-LumiNova. Scratch-resistant sapphire crystal with anti-reflective treatment on both sides protects the sand-blasted 950 platinum dial that gives a classic and elegant update to the Moonwatch and features two chronograph sub-dials at 3 and 9, a date window at 6, Moonwatch-style hands with Super-LumiNova for excellent readability. Water resistant to 50m, this legendary watch is powered by the revolutionary Omega Co-Axial calibre 9300 automatic movement which is the first of their in-house movements to incorporate a chronograph function, and is finished with a column wheel mechanism and a Si14 silicon balance spring. The perfect way to pay tribute to Omega's passion for space exploration, the innovative materials and a ground-breaking mechanical movement are just a few of the impresive features that have attracted so many loyal Speedmaster fans.
