  • Omega caliber 9300 beats at 28,800 vph, contains 54 Jewels & has an approximate power reserve of 60 hours - thanks to its twin barrels mounted in series.
  • Column-Wheel Chronograph - The column wheel is visible from the transparent case back.
  • The movement features Omega's "Si 14" silicon balance spring, which contributes to the movement's outstanding resistance to shock and environmental disturbances and, thus, to the watch’s chronometric performance.
  • The movement also features the now-standard Co-Axial Escapement, contributing to greater precision, stability & durability. The Co-Axial escapement has less friction & reduces the necessity of lubrication, thus reducing the time required between servicing.
  • The combination of the SI 14 balance spring & the Co-Axial escapement makes for an extremely reliable & stable movement.
  • The rotor & visible bridges are decorated with a unique "arabesque" wave design finish.
