The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moons, as well as the “claws” on the side of the case. This 41 mm stainless steel model features a polished blue ceramic bezel with Roman numerals in “Grand Feu” white enamel, a white ceramic dial and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and facetted indexes are all blued. Presented on a stainless-steel bracelet, this timepiece is driven by the OMEGA Co-Axial Master Chronometer Calibre 8900, visible through the domed scratch-resistant sapphire crystal. <ul><li>41mm stainless steel case</li><li>White ceramic dial</li><li>Domed scratch-resistant sapphire crystal with anti-reflective treatment on both sides</li><li>Anti-magnetic</li><li>Date</li><li>Time zone function</li><li>OMEGA Co-Axial Master Chronometer Calibre 8900 self-winding movement</li><li>Master Chronometer Certified</li><li>60 Hour power reserve</li><li>Transparent case back</li><li>Stainless steel bracelet</li><li>Water resistance: 5 bar (50 metres / 167 feet)</li><li>OMEGA Style #: O13130412104001</li></ul>
