Brand new Omega Speedmaster Moonwatch 310.63.42.50.02.001 .The core of the professional lunar watch Speedmaster story is that it was the watch worn by Armstrong when he went to the moon, and it was left inside the spacecraft. The case is made of imported 316 stainless steel, featuring finely detailed angles and a prominent 3D design on the bezel. The dial's luminous material is made from Swiss-imported luminescent material, crafted through multiple printing processes. It is paired with a sapphire crystal with a cooking pot design, and the case size is 42mm, which can be matched with either a stainless steel bracelet or a NATO military strap. The movement uses the classic 3861 Master Chronometer manual-winding chronograph movement; a complete experience with a manual chronograph is essential! You won't know until you try!
