Omega Speedmaster Professional Moonwatch SS Black Dial

The Omega Speedmaster Professional Moonwatch 310.30.42.50.01.002 pays direct homage to the iconic chronograph that played a crucial role in space exploration history. Building on the legacy of the 4th generation Speedmaster that accompanied astronauts on lunar missions, this current generation preserves classic elements, including its 42mm asymmetrical stainless steel case and the beloved black step dial with applied Omega logo. At the core is the hand-wound Omega Co-Axial Master Chronometer Calibre 3861, which delivers a significant technical advancement in accuracy and magnetic resistance, while maintaining the traditional architecture admired by purists. The dial is balanced with three sub-counters for small seconds, 30-minute, and 12-hour chronograph recorders, a configuration directly derived from vintage models favored by NASA. Collectors value the hesalite crystal—a nod to the original Moonwatch used on the Apollo missions—and the solid caseback with the embossed Seahorse medallion. The five-arched-links-per-row bracelet accentuates its professional tool watch character. This reference is universally recognized for both its horological and historical significance, providing an enduring link to man's greatest adventure and representing one of the most trustworthy and revered chronographs available to connoisseurs.
