The all-new Omega Speedmaster 310.63.42.50.02.001 Moonwatch is a professional lunar watch. The core story of the Speedmaster is that it was worn by Armstrong during the moon landing and left behind in the spacecraft. The case is made of imported 316 stainless steel, featuring delicate angles and a three-dimensional appearance, complemented by a matching bezel. The watch dial uses Swiss-imported luminous material, created through multiple printing processes. It is fitted with a sapphire crystal and has a case size of 42mm, compatible with either a stainless steel bracelet or a NATO military strap. The movement is the classic 3861 Master Chronometer manual-winding chronograph. A complete experience of the manual chronograph is a must-try! You won't know until you try!
