Paying homage to Omega's diving heritage, this Omega Seamaster Planet Ocean 600m co-axial master chronometer watch is the result of the brands extensive ocean exploration. Showcasing immaculate design, this impressive watch is fastened with a fine-brushed stainless steel bracelet with patented extendable foldover clasp and features a 39.5mm stainless steel case with a black ceramic unidirectional bezel with the Omega Liquidmetal diving scale. Domed and scratch-resistant sapphire crystal with anti-reflective treatment on both sides protects the black dial that displays the silver tone baton and Arabic numeral hour markers and silver tone hands with a date window at 3 o'clock. With an excellent water resistance of 600m, this beautifully made watch is powered by a self-winding movement with Co-Axial escapement and an Omega 8800 calibre and power reserve of 55 hours. To achieve its impressive Master Chronometer status, this timepiece has passed the eight meticulous tests set by METAS (The Swiss Federal Institute of Metrology) to ensure the highest standards of watchmaking.
