The new Omega Speedmaster Mark II is based on a model released in 1969, the same year that astronauts wore Omega Speedmaster Professional watches on the surface of the moon, forever earning that model the nickname “Moonwatch.” The original Speedmaster Mark II contained the same hand-wound mechanical caliber that powered the Moonwatch, Omega’s Caliber 861. The modern version has been updated, with an automatic movement (Omega’s co-axial Caliber 3330, with silicon balance spring and column-wheel chronograph mechanism) and a cleverly executed tachymeter scale that glows in the dark.
The barrel-shaped case has brushed and polished finishes; the crown and chronograph pushers are polished. The tricompax dial features subdials at 3 o’clock (30-minute counter), 6 o’clock (12-hour counter), and 9 o’clock (small seconds). The tachymeter scale is printed on the flat, scratch-resistant sapphire crystal and illuminated from beneath by an aluminum ring filled with Super-LumiNova. The version with a black dial has a varnished white central chronograph hand; the one with gray dial uses fluorescent orange for this hand, as well as for the minute track. The Speedmaster Mark II has a brushed stainless steel bracelet with Omega’s patented extendable fold-over rock-and-pusher clasp. The watch is water-resistant to 100 meters and comes with a four-year warranty.
