![]() It will probably only be a matter of time before other movements will also receive this upgrade.įor the owner of this Speedmaster Super Racing, it means that your watch is incredibly precise and certified by METAS. The brand used the caliber 9900 as a basis to adopt it, resulting in the caliber 9920 (4hz frequency movement). Omega’s new Speedmaster Super Racing watch is the first model to feature this new Spirate System. ![]() In a later article, we will go into detail about the development of the Spirate system. Needless to say, this chronograph 9920 movement, like the caliber 9900 series, has a column-wheel mechanism. To be sure, the fine-tuning done via the adjustment system on the balance bridge is on top of the micro-screws on the balance wheel. As a result, the movement can be fine-tuned to achieve an average deviation of 0/+2 seconds per day versus the already-impressive 0/+5 seconds per day. Using an eccentric adjustment mechanism (Omega refers to it as the graduated tuner) on the balance bridge, a watchmaker can act on the stiffness of the hairspring’s attachment point. This is the most complicated component of the regulating organ, so creating the new Spirate system was a huge challenge. With this new system, Omega can now achieve a precision of 0/+2 seconds per day on average, certified by METAS.įor this, Omega had to redesign the Si14 balance spring. It’s a new patent-pending spiral that, according to Omega, allows for ultra-fine rate adjustments. ![]() The new Omega Speedmaster Super Racing features a Spirate (this name is a combination of spiral and rate) system. The result? A watch that offers an average accuracy of 0/+5 seconds per day and that is antimagnetic to 15,000 gauss. The certification is performed by an independent Swiss organization (METAS) and consists of eight tests performed over 10 days. This meant that chronometer movements would be tested and certified (again) after they were cased. In 1964, the distinctive twisted lugs where introduced, which allowed for an asymmetric case that in turn protects the crown and pushers.Globemaster with caliber 8901, the first Master Chronometer watch from OmegaĪnd then, two years later, in 2015, Omega introduced the Master Chronometer certification for its watches (starting with the Constellation Globemaster and its caliber 8900/8901). This watch was strapped to astronaut Ed White when he made his spacewalk on June 3, 1965, and featuring its simplified calibre 861 was worn by Neil Armstrong and Buzz Aldrin when they took their giant leaps on the lunar surface in 1969. In 1963, the third generation was the first watch to pass NASA’s strict testing and was worn on Gemini and Apollo missions. Like its predecessor, it featured the highly collectable Calibre 321 movement. It was also the first to be worn in space on the wrist of Walter Schirra on October 3, 1962. Two years later, a second version was released with a black aluminium bezel, lollipop seconds hands for Air Force orders and 'Alpha' style hour and minute hands for better legibility. ![]() However, when it comes to speed, I’m sure there’s nothing quite as exhilarating as jetting off to the moon. It is not only one of the most iconic chronographs, it was the first chronograph wristwatch with its tachymeter scale engraved on the bezel - a feature designed for the benefit of racing drivers. The original Speedmaster 'Broad Arrow' was created in 1957 and was so named because of its distinctive hands. ![]()
