In Omega’s own words:

“Driving the Speedmaster Super Racing is OMEGA’s Co-Axial Master Chronometer Calibre 9920, complete with OMEGA’s new Spirate™ System. Both the movement and assembled watch undergo the industry’s strictest tests to guarantee the highest levels of performance, precision and magnetic resistance. ” –source

Spirate System:

The calibre 9920 is the first Omega movement to feature the brand’s new patent-pending Spirate System. Spirate being a portmanteau of spiral and rate. Omega describes this new technology as “a revolutionary new spiral that allows for ultra-fine rate adjustments to achieve certified precision of only 0/+2 seconds a day.Read more on the Spirate System here.

Omega Spirate


As mentioned above, thanks to the patent-pending Spirate System in the 9920, Omega claims that this caliber can be regulated to maintain an average accuracy rate of 0 to +2 seconds per day. The 9920 is a Certified Master Chronometer,
approved by METAS

Anti-Magnetic Properties:

It used to be that the Omega caliber 8508 got all of the credit for being resistant to magnetic fields, but now most of the newer movements such as the cal. 9920 being discussed here, are anti-magnetic up to 15,000 gauss thanks to the silicon balance spring and materials that are not affected by exposure to magnetism.

Tribute 10 Datewheel:

Coinciding with the colorway of the Super Racing Speedy, the datewheel on the 9920 is black and yellow with a special font for the number “10”. Omega calls this Tribute 10 in honor of the Seamaster Aqua Terra >15,000 Gauss “Bumblebee” introduced at Baselworld 2013, 10 years ago (it is the watch powered by the 8508 mentioned above). This means that the datewheel for the 9920 is a specific part, but you may potentially be able to obtain a Tribute 10 datewheel in the future to mod an existing 9900 based watch. This still needs confirmed, and not that anyone would want to do that, but it may be a possibility.
