Brushed finished stainless steel case with polished finished beveled corners. Black ceramic bezel with a Liquidmetal™ Tachymeter scale in orange & silver. Matte black dial. Applied polished index hour markers with luminescent fill & orange dot hour markers. Fine printed RACING style minute/seconds & fractions of a second track. Orange time related hands, hour & minute hands with luminescent fill. White chronograph related hands. Small continuous running seconds hand sub-dial located at the 9 o'clock position. Date window displayed at the 6 o'clock position. Chronograph Stopwatch functions: Large white central seconds hand counter with an orange tip . Minute & hour counters are combined into a single sub-dial located at the 3 o'clock position. Movement: Omega Master Co-Axial caliber 9900, beats at 25,200 vph, contains 54 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.

The energy produced from the wound spring drives the movement functions. An automatic watch has a weighted rotor mounted on a pivot to the back of the movement, and the rotor is connect to the mainspring through a series of gears. The natural motion of the wearers wrist will cause the rotor to spin, which in turn will automatically wind the mainspring. Please note: An automatic winding watch which has completely wound-down or is at the end of its power reserve requires manual winding. Manually winding an automatic watch ensures that the watch is at full power-reserve when first worn, and as long as the watch is in motion thereafter it will remain fully wound, ensuring that when the watch is removed it will run the specificed power-reserve duration.
