The Omega Speedmaster Professional "Moonwatch" reference 3570.50.00 is an iconic watch, famous for being the first watch worn on the Moon. Launched in 1996 and produced until 2014, this model remained true to the design of watches used in the Apollo space missions. It is powered by the manual-winding Caliber 1861 movement, an evolution of the Lemania 861 movement, renowned for its robustness and reliability. The 42 mm stainless steel case houses a black dial with chronograph functions and a tachymeter scale, protected by a Hesalite crystal. The watch is water-resistant up to 50 meters.
