Model #: 304.33.44.52.03.001 Omega Speedmaster Moonphase Co-Axial Master Chronometer Chronograph 44.25mm Mens Watch

Brushed/Satin finished stainless steel case with polished finished beveled corners. Stainless steel bezel ring with with polished blue ceramic fill & satin finished Liquidmetal Tachymeter scale. Metallic blue dial with a fine sunburst finish. Applied index hour markers with luminescent fill. Printed white minute/seconds & fractions of a second track. Polished hour & minute hands with luminescent fill. Chronograph Stopwatch functions: Large central seconds hand counter with luminous spear-head tip . Minute (steel) & hour (white) hand counters are combined into a single sub-dial located at the 3 o'clock position. Small continuous running seconds hand at the center of the sub-dial at the 9 o'clock position. Date displayed on the perimeter of the sub-dial at the 9 o'clock position, indicated via the red circular tipped hand. Moonphase display sub-dial at the 6 o'clock position. The moonphase features two infinitely small yet photo-realistic moons on a metallic crystal disc microstructured to obtain a high resolution image of the moon. Movement: Omega Master Co-Axial caliber 9904, beats at 28,000 vph (4Hz), 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, with its COSC chronometer movement, 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 Alternate model # 30433445203001 Condition : New/Unworn Case Shape : Round Case Dimensions : 44.25mm Case Material : Stainless Steel Dial Color : Blue Crystal : Scratch Resistant Sapphire Bezel : Fixed Screw-in Crown : No Water Resistance No ratingDoes not allow contact with water 30m/99ft - 50m/165ftAllows for contact with water such as washing hands and rain 50m/165ft - 100m/330ftAllows for light poolside swimming 100m/330ft - 200m/660ftAllows for swimming, snorkeling and showering (do not expose to hot water) 200m/660ft - 500m/1650ftAllows for impact water sports such as board diving and scuba diving 500m/1650ft +Appropriate for serious deep water diving.

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.
