From the retailer listing

An enduring classic, re-touched for the modern man 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 blue leather strap with rubber lining, this timepiece is driven by the OMEGA Co-Axial Master Chronometer Calibre 8900, visible through the domed scratch-resistant sapphire crystal.
