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 features a hard metal scratchproof fluted bezel, with a rhodium-plated Constellation star, and hands and indexes which have also been filled with illuminous Super-LumiNova.
The caseback includes a stainless steel Central Observatory medallion, while the sun-brushed blue "Pie Pan" dial is reminiscent of the first 1952 Constellation model.
The design is finished with a new 3-row stainless steel bracelet with slightly curved central links, and at its core, the watch is driven by OMEGA's Co-Axial Master Chronometer Calibre 8900, featuring revolutionary anti-magnetic technology.
