The Omega Constellation Globemaster (Ref. 130.23.39.21.03.001) holds the distinction of being the world’s first watch certified as a Master Chronometer, combining the brand’s aesthetic heritage with the cutting-edge technology of Swiss haute horlogerie. Crafted from a refined combination of stainless steel and 18Kt Sedna™ Gold—OMEGA’s exclusive, color-stable rose gold alloy—this 39 mm model stands out for its iconic fluted bezel with rounded edges and ergonomic dimensions (46.70 mm from lug to lug).

Its blue dial with a sunburst brushed finish revives the famous faceted “Pie-Pan” design from 1952. The dial features hands, applied hour markers, and the collection’s distinctive star—all crafted from 18Kt Sedna™ Gold with a Super-LumiNova luminescent coating—accompanied by a date window at the 6 o’clock position. The watch is protected by a scratch-resistant convex sapphire crystal with an anti-reflective coating on both sides, paired with an elegant blue leather strap, for a total weight of 94 grams.

Inside, the OMEGA Caliber 8900 self-winding movement beats, visible through the sapphire crystal case back.

Certified to METAS’s stringent Master Chronometer standard, this dual-barrel movement offers a 60-hour power reserve, an independent hour-jump function for travel, and complete immunity to everyday magnetic fields of up to 15,000 gauss. The case back also ensures water resistance to 10 bar (100 meters).
