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 the now-standard 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 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.
