Annual calendar complication:
The annual calendar complication will accurately account for the current number of days in each month with the exception of the 29th day of February in a leap year.
Date window located at the 3 o'clock position.
Month displayed via the shorter central hand pointing to the current month, printed between the hour markers.
A medallion with Omega's constellation emblem, an image of an observatory surrounded by a polished sky marked with eight symbolic stars.
Omega master co-axial caliber 8922, beats at 25,200 vph, contains 39 jewels and 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 and durability.
The co-axial escapement has less friction and reduces the necessity of lubrication thus reducing the time intervals required between servicing.
The rotor and visible bridges are decorated with a unique "arabesque" wave design finish.
