Swiss Federal Institute of Metrology (METAS) certified Master-Chronometer. The finished watch movement is a COSC chronometer, passes tests that replicate real-life wearing conditions. The METAS certification tests water resistance, precision and magnetic resistance to 15'000 gauss.
Anti-magnetic: resistant to magnetic fields greater than 15'000 gauss.
The movement features Omega's "Si 14" silicon balance spring, which contributes to the movements outstanding resistance to shock and to environmental disturbances and thus to the watch's chronometric performance.
The movement also features Omegas Co-Axial Escapement which contributes to greater precision, stability & durability. The Co-Axial escapement has less friction & reduces the necessity of lubrication thus reducing the time intervals required between servicing
The rotor & visible bridges are decorated with a unique "arabesque" wave design finish.
