The Omega Speedmaster Professional is a watch that's indelibly linked to the Space Program, in particular the Apollo program.
In 1967, the United States, the United Kingdom, and the Soviet Union signed the Outer Space Treaty. The Treaty set the guidelines of international space law--in particular, it banned the use of nuclear weapons in space. To date, over 104 nations have signed and ratified the treaty, keeping the solemn promise laid down in the National Aeronautics and Space Act of 1958 that "all activities in space should be devoted to peaceful purposes for the benefit of all mankind."
The year also marked achievements for NASA that would lay the groundwork for the Apollo missions. Having already achieved a spacewalk in 1965 (undertaken by astronaut Edward White, whose own tragic history is linked to the Speedmaster), NASA turned its attention to determining suitable landing sites on the Moon. From 1966 to 1967 NASA launched a series of five unmanned Lunar Orbiters. In the final Lunar Orbiter launch, in August of 1967, over 900 images were taken of the Moon, including the Far Side. As a result, over 99% of the Moon was photographed, allowing NASA to select potential landing sites for the Apollo program.
Meanwhile, back in Bienne, Omega was making subtle changes to the Speedmaster. In 1967, Omega released a new reference of Speedmaster that would set the standard for all Speedmasters to follow. The Reference 145.012-67 was the last of the Apollo-Era Speedmasters to utilize the Calibre .321 column wheel chronograph movement by Lemania; the next reference, the 145.022, would use the improved Caliber .861.
Also, certain examples of the Reference 145.012 were designated SP, for Spécial Poussoirs or "special pushers," meaning that these examples had unique pushers with taller caps installed in order to improve water resistance.
With its characteristic applied-logo dial and "Dot Over 90" bezel, this example possesses a sharp case with lovely twisted lugs, and a Hesalite crystal. The Pre-Moon case back features the Omega Hippocampus. The dial is in beautiful condition, with a rich patina to the Tritium elements of the hour markers and hands.
Though perhaps not as desired as earlier Speedmasters like the Ed White or the 2915, the Reference 145.012-67 has a deep connection to NASA, being the same Reference worn by Buzz Aldrin in the historical Apollo 11 mission, and by Alan Shephard in Apollo 14, making it an important historical artifact with ties to NASA that cannot go understated.
