The Omega caliber 9900 is an automatic column wheel chronograph movement with 54 jewels and a beat rate of 28,800bph. This movement was first introduced in the Omega Seamaster Planet Ocean at Baselworld 2016. It was Omega’s first caliber to be METAS certified.

In Omega’s own words:

“Self-winding chronograph with column wheel and Co- Axial escapement. Certified Master Chronometer, approved by METAS, resistant to magnetic fields reaching 15,000 gauss. Silicon balance-spring, 2 barrels mounted in series, time zone function. Central hour, minute and chronograph seconds hands, small seconds hand, 12-hour and 60-minute recorders. Rhodium plated finish with Geneva waves in arabesque.” –source

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. 9900 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.

Replacement Prices:

The Omega caliber 9900 is an in-house movement and not available for individual purchase, even for Swatch Group parts accounts. At the time of this post, this movement is only found in the Seamaster Diver 300M Chronograph, Seamaster Planet Ocean 600M Chronograph, and Speedmaster Racing models with retail prices ranging between $7,500 to $31,600 USD.
