The Globemaster is already a legendary name in the OMEGA family. Now it has been updated to become the world's first Master Chronometer, further enhancing its reputation within the watchmaking industry.
Along with a new standard of quality, the simple yet captivating design makes this watch a true object of desire. For this model, the stainless steel case is brought to life by a rich 18K Sedna™ gold fluted bezel, the same material used on the Constellation star, and hands and indexes which have also been filled with illuminous Super-LumiNova.
What truly makes this timepiece special is the sun-brushed blue dial, created in the classic "Pie Pan" style that is inspired by the first 1952 Constellation model.
Complementing the case and bezel, the new 3-row bracelet has been included with slightly curved central links made from stainless steel and 18K Sedna™ gold. At its core, the watch is driven by OMEGA's Co-Axial Master Chronometer Calibre 8900, featuring revolutionary anti-magnetic technology.
