The Omega Speedmaster Professional is one of the most iconic chronographs in watchmaking history. Known as the "Moonwatch," this model was used in NASA's Apollo missions and was the first watch to land on the Moon.
Ref. 310.30.42.50.01.001 is the new-generation Speedmaster introduced in 2021. With its 42 mm stainless steel case, black dial, and Co-Axial Master Chronometer-certified Caliber 3861 movement, it combines both historical heritage and modern technology.
