Omega Master Co-Axial caliber 8903, beats at 25,200 vph, contains 39 Jewels & has an approximate power reserve of 55 hours, courtesy of its twin barrels mounted in series.
Swiss Federal Institute of Metrology (METAS) certified Master-Chronometer. The finished watch, whose 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. In addition to measuring the performance of the watch in daily wearing conditions, the process also ensures that the watch and its movement function properly when exposed to magnetic fields of 15,000 gauss.
Features Omega's Si14 silicon balance spring that improves resistance to shock and magnetism and thus to sustained reliability.
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.
