OMEGA Speedmaster Professional From the Moon to Mars - Reference 3577.50.00

The legendary "Moon Watch" flight-qualified by NASA for manned spaceflight missions in 1965 and the only watch ever to be worn on the moon. Its timeless design remains ever-popular: stainless steel case and bracelet, OMEGA calibre 1861 mechanical hand-winding chronograph movement with hour and minute display, continuous small seconds hand, central chronograph seconds hand, 30 minute and 12 hour totalisers, and a power reserve of 45 hours. The Speedmaster Professional has luminous hands and hour markers (Super Luminova), a hesalite crystal as used on the original model and a screw-in case-back ensuring water resistance to 50 metres. The tachymeter scale on the black aluminium ring of the steel bezel allows calculation of a vehicle's speed, a machine's hourly production etc. The three counters on the dial bear depictions of the Earth, the Moon and Mars and the dial bears the inscription "From the Moon to Mars" between 5 o'clock and 3 o'clock. The same inscription is found on the case back, which also bears a sequential number. "
