Omega Speedmaster Moonwatch Professional 3861 Sapphire 310.30.42.50.01.002

Overview 

The Omega Speedmaster Moonwatch Professional reference 310.30.42.50.01.002 stands as the definitive modern iteration of one of horology's most iconic timepieces, embracing its legendary lineage while proudly showcasing its technical evolution. Directly descended from the watches worn on all six lunar missions, this model retains the timeless aesthetic of the original but is distinguished by its use of sapphire crystal on both the front and back, providing a clear window into its mechanical heart.

The watch’s 42mm stainless steel case faithfully adheres to the classic Moonwatch proportions, featuring Omega’s signature twisted lugs for a refined touch. A scratch-resistant sapphire crystal protects the iconic black step dial, which provides exceptional legibility with its contrasting white hour markers and hands. A black anodized aluminum tachymeter bezel, true to the "dot over 90" design, completes the iconic look, offering a bold and functional element for measuring speed. This model is paired with a robust brushed stainless steel bracelet, designed for optimal comfort and versatility across all occasions.

At the heart of this reference beats Omega’s groundbreaking Co-Axial Master Chronometer Calibre 3861. This state-of-the-art manual-winding movement represents a significant upgrade, combining the historical charm of the original Moonwatch with modern advancements. It boasts a Co-Axial escapement, a silicon balance spring, and METAS certification, ensuring unparalleled precision and superior resistance to magnetic fields. With a robust 50-hour power reserve, this movement guarantees reliability and performance. A sapphire exhibition caseback provides a stunning view of the beautifully finished calibre, allowing the wearer to admire the intricate mechanics that power this legendary watch.

This Speedmaster’s transparent caseback and updated mechanics appeal to purists and collectors who cherish both the rich heritage and the cutting-edge innovation of a legendary timepiece. The 310.30.42.50.01.002 is the current production reference for the standard Moonwatch Professional, continuing its journey as a true icon of watchmaking and human endeavor.
