The 3570.50.00 is the watch that anchored the Speedmaster Professional line from the mid-1990s until its eventual replacement in 2014. The watch utilizes the iconic asymmetrical case geometry that integrates guarded pushers and a protected crown
Powering the model is the caliber 1861, a manually wound mechanical movement operating on a cam-actuated chronograph system. The dial displays a high-contrast layout with three recessed sub-registers under a domed Hesalite crystal, maintaining strict adherence to mid-century aviation specifications.
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.
