The Cal. 9900 is more than just a pretty movement. It's dual-rated with COSC and METAS certifications. METAS refers to the Swiss Federal Institute of Metrology and these folks actually evaluate the testing procedures that Omega uses as an additional layer of reassurance. All very meta. And of course the COSC certification is backed by link the Contrôle link Officiel Suisse des Chronomètres found on many high-grade movements. This is where the "Master" moniker is link derived from.
