The Omega Globemaster Co-Axial Master Chronometer reference 130.30.39.21.03.001 is a 39mm stainless steel timepiece that features a sun-brushed blue pie-pan dial, a design element inspired by the 1952 Constellation model. The watch is distinguished by its hard metal, scratch-proof tungsten carbide fluted bezel and a sapphire exhibition caseback featuring a Central Observatory medallion. It is powered by the Omega Calibre 8900, a self-winding movement with a Co-Axial escapement and a 60-hour power reserve. As the world’s first Master Chronometer, the movement is certified by METAS to withstand magnetic fields of up to 15,000 gauss and maintain a precision of 0 to +5 seconds per day.
The complications of this model include a date display at the 6 o’clock position and a time zone function that allows the wearer to adjust the hour hand independently without stopping the watch, making it a practical choice for travel. The watch is water-resistant to 100 meters and features a 3-row stainless steel bracelet with a butterfly clasp. Additional technical specifications include a silicon balance spring for enhanced magnetic resistance and a domed, scratch-resistant sapphire crystal with anti-reflective treatment on both sides.
General reviews frequently highlight the Globemaster as an understated and versatile “Go Anywhere, Do Anything” watch that serves as a technically superior alternative to mainstream competitors. Enthusiasts often praise the unique light play of the pie-pan dial and the durability of the tungsten bezel, though some critics note the lack of a screw-down crown and the absence of micro-adjustment on the bracelet. While it is widely respected for its historical heritage and movement quality, it is sometimes described as a “hidden gem” that remains less ubiquitous than other Omega sports models.
