Omega Speedmaster Professional Moonwatch Master Chronometer

Omega elevates the legendary Speedmaster with Master Chronometer certification and Co-Axial escapement technology. The new calibre 3861 movement resists magnetic fields up to 15,000 gauss while maintaining the classic Moonwatch aesthetic. Hesalite crystal and steel case preserve the original 1969 moon landing heritage. The manual-winding movement features rhodium-plated finish and offers 50-hour power reserve. NASA continues to qualify this timepiece for all manned space missions, maintaining its status as the only watch flight-qualified for spacewalks.
