The 41mm stainless steel Constellation retains the core design elements established by the 1982 Manhattan model, specifically the four lateral claws originally engineered by Carol Didisheim to compress the crystal for water resistance. On reference 131.33.41.21.03.001, these fixed steel claws grip a polished blue ceramic bezel inlaid with Liquidmetal Roman numerals. The sun-brushed blue dial integrates a date aperture at six o'clock and utilizes faceted, rhodium-plated hands to indicate the time.
The watch is driven by the Calibre 8900, an automatic movement that has been METAS certified. This requires the fully cased watch to pass eight distinct criteria, including maintaining mechanical stability during exposure to magnetic fields reaching 15,000 gauss. Internally, the caliber operates at 25,200 vibrations per hour and employs a Co-Axial escapement paired with twin barrels mounted in series to generate a 60-hour power reserve.
Founded in 1848 by Louis Brandt in La Chaux-de-Fonds, Switzerland, the company that would become Omega established its identity with the 1894 introduction of the 19-ligne 'Omega' calibre. This movement was a landmark in industrial watchmaking, utilizing interchangeable components to streamline production and repair—a philosophy of accessible precision that continues to define the brand.
Omega cemented its reputation for robust accuracy through its role as the Official Timekeeper for the Olympic Games since 1932 and, most famously, through the Speedmaster Professional's flight qualification by NASA, which culminated in its journey to the Moon.
In the modern era, the brand's most significant contribution has been the industrialization of the co-axial escapement, an invention by Dr. George Daniels that fundamentally reduces friction within the calibre for superior long-term chronometric stability. Typified by purpose-driven design, Omega's collections—from the abyssal-depth Seamaster to the iconic Speedmaster—are archetypes of the professional tool watch, balancing legible aesthetics with advanced material science and anti-magnetic properties through its Master Chronometer certification.
