Omega Speedmaster 310.30.42.50.01.002

The Omega Speedmaster Professional Moonwatch 310.30.42.50.01.002 is a horological icon that celebrates Omega’s legacy in space exploration, featuring a 42mm stainless steel case with the signature asymmetrical design that has made it one of the most recognizable chronographs in history. This legendary timepiece boasts a black step dial with applied hour markers and the classic tri-compax layout, including a small seconds sub-dial at 9 o’clock, 30-minute recorder at 3 o’clock, and 12-hour recorder at 6 o’clock, all powered by the manual-winding Caliber 3861. This Master Chronometer-certified movement delivers exceptional precision with resistance to magnetic fields up to 15,000 gauss and a 50-hour power reserve, visible through the sapphire crystal caseback that showcases the movement’s exquisite finishing with Geneva waves decoration. The black ceramic bezel features a white enamel tachymeter scale for precise speed calculations, while the sapphire crystal (with anti-reflective treatment on both sides) offers enhanced scratch resistance and clarity compared to traditional Hesalite. The stainless steel bracelet with flat-link design and folding clasp provides both comfort and durability, maintaining the watch’s authentic 1960s aesthetic. Water-resistant to 50 meters, this Moonwatch retains its professional tool-watch functionality while offering modern refinements. As the only watch certified by NASA for all manned space missions and the first worn on the moon, this Speedmaster represents a pinnacle of human achievement and Omega’s pioneering spirit in watchmaking. Whether worn as a tribute to space exploration, a precision timing instrument, or a statement of horological passion, this watch stands as a testament to Omega’s commitment to excellence. With its perfect 42mm proportions, historical significance, and blend of vintage design with modern technology, the Speedmaster Professional Sapphire Sandwich is destined to be cherished by collectors and enthusiasts as both a functional chronograph and a piece of wearable history.
