Omega Speedmaster Moonwatch Professional 310.30.42.50.04.001 – History
The Omega Speedmaster Moonwatch Professional is one of the most iconic chronographs in horological history, renowned for its unrivaled legacy in space exploration and its classic, purposeful design. This legacy began in the late 1950s with the original Speedmaster chronograph and was forever cemented when the Moonwatch became the first wristwatch worn on the lunar surface during NASA’s Apollo missions.
The reference 310.30.42.50.04.001 represents a modern chapter in this storied lineage. Introduced in 2024, this version updates the classic Moonwatch formula with contemporary materials and a Master Chronometer-certified movement, while maintaining the design cues that define the Speedmaster aesthetic. It is one of the first regular production Speedmaster Moonwatches to feature a white lacquered dial, a striking departure from the traditional black that refreshes the Moonwatch identity for a new generation of collectors.
Built around Omega’s famous asymmetrical 42 mm stainless steel case, this version bridges the brand’s rich heritage with advanced mechanics — delivering the performance and presence that enthusiasts expect from a modern professional chronograph.
Design and Aesthetic
The Speedmaster 310.30.42.50.04.001 retains the unmistakable Moonwatch silhouette defined by its 42 mm asymmetrical case and tachymeter bezel, but introduces compelling visual flair with a glossy white lacquer dial and contrasting black chronograph registers.
The dial features crisp applied hour markers and Moonwatch-style hands, ensuring classic legibility and a distinctive look on the wrist. Subdials display running seconds, a 30-minute chronograph counter, and a 12-hour totalizer in the traditional layout familiar to Speedmaster fans.
A domed sapphire crystal with anti-reflective treatment protects the dial up front, while a sapphire exhibition caseback lets you admire the chronograph movement within — a feature prized by collectors who appreciate both form and function.
The fixed black tachymeter bezel insert retains an essential aspect of the Speedmaster’s tool-watch heritage, allowing measurement of average speed over distance — a reminder of the model’s motorsport and aerospace roots.
