• Brushed black ceramic case with polished finished beveled corners, crafted from a single block of ceramic.
• Bezel:
• Matte black ceramic bezel with polished finished ceramic top.
• Satin finished Liquidmetal diving scale markings & numbers.
• Luminous dot at the starting point (green colored emission).
• Dial:
• Polished black zirconium oxide ceramic dial, with [ZrO2] engraved on the dial directly below the center hands.
• Applied polished white gold index hour with luminous fill (blue colored emission).
• Applied blue 6, 9 & 12 hour markers.
• Silver printed minute/seconds track.
• Polished white gold hands with luminous fill (hour & seconds hands with blue colored emission, minute hand with green colored emission).
• Date window located at the 3 o'clock position.
• Helium escape valve located on the case edge at the 10 o'clock position.
• GMT/2nd Time-zone:
• Indicated by the orange spear-head hand with a luminous filled tip. This hand makes a single rotation every 24 hours & points to the desired GMT timezone on the bezel.
• The additional time is indicated in a black 24 hour chapter ring on the dial perimeter. The reason for the 24 hour mode is to eliminate confusion between day & night at the desired time-zone.
• Screwed-in transparent case back with the engraving oriented & aligned with the watch, thanks to Omega's patented "Naiad Lock".
• Movement:
• Omega Master Co-Axial caliber 8906, beats at 25,200 vph, contains 38 Jewels & has an approximate power reserve of 60 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.
