The Omega Constellation Co-Axial Master Chronometer reference 131.33.41.21.04.001 is a 41mm luxury timepiece featuring a stainless steel case with the collection’s signature half-moon facets and claws. This model is distinguished by a polished blue ceramic bezel with Roman numerals in Grand Feu white enamel and a crisp white ceramic dial. The dial is adorned with blued hands, indexes, and a date window positioned at 6 o’clock. It is paired with a blue alligator leather strap that includes a comfortable rubber lining and a foldover clasp.
Inside, the watch is powered by the Omega Calibre 8900, an automatic, anti-magnetic movement that is Master Chronometer certified by METAS. This movement features a co-axial escapement, two barrels providing a 60-hour power reserve, and a time zone function that allows the hour hand to be adjusted independently. The movement’s refined finish, including Geneva waves in arabesque, is visible through a transparent sapphire crystal caseback. The watch is water-resistant to 50 meters and protected by a domed, scratch-resistant sapphire crystal with anti-reflective treatment on both sides.
General reviews of this 41mm iteration often praise its modern and masculine update to the classic Constellation design, noting that the increased size and ceramic bezel add a sportier, more versatile character. The combination of the white dial and blue accents is frequently highlighted for its fresh and bold aesthetic. While the build quality and Master Chronometer movement receive high marks for precision and durability, some reviewers suggest that the 13.5mm thickness makes it lean more toward a casual everyday watch than a traditional slim dress watch. Additionally, the unique lugless case design is noted for its exceptional comfort on various wrist sizes.
