The Speedmaster Professional Mark II has the same Caliber 861 as the Speedmaster ‘Moonwatch’. It was launched in 1969, the year of the landing on the moon, which also meant the renaming of the Speedmaster and the change in the case back engraving to include first watch worn on the moon.
The Omega Speedmaster Professional Chronograph, also known as the "Moonwatch", is famous for being the watch worn by astronauts during the first Moon landing.
Omega had also been developing improvements and modifications to the Speedmaster that they wished to submit to NASA.
NASA’s harsh and intense qualification tests leading up to the Apollo 11 mission examined several watches from Switzerland’s top manufacturers such as Breitling, Rolex and Omega; the testing was concluded in March 1965 with the final selection awarded to the Omega Speedmaster, because it stood apart from the rest as it continuously kept within 5 seconds accuracy in its per day rate. As a result, it became the official watch of the U.S. space program.
The Speedmaster Mark II has the same movement and quality as its predecessor with a redesigned case and different material glass.
