Omega Speedmaster Moonwatch Professional Chronograph Steel White Dial Rubber Strap 310.32.42.50.04.001 Omega Speedmaster Moonwatch Professional Chronograph Steel White…

The Omega Speedmaster Moonwatch Professional is one of the most historically significant wristwatches ever produced, and reference 310.32.42.50.04.001 represents the collection in its most refined modern form. First worn by NASA astronauts during the Apollo missions of the 1960s and certified for extravehicular activity in space, the Speedmaster Moonwatch has remained in continuous production and continuous relevance for decades — a rare achievement in haute horology. This particular configuration brings a striking white index dial to the legendary silhouette, making it immediately recognizable as a Moonwatch while offering a luminous freshness that sets it apart on the wrist.

At 42mm in stainless steel, the case dimensions honor the proportions that made the original Speedmaster so wearable and so enduring. The polished and brushed steel case construction is executed with the fit and finish standards Omega maintains across its professional catalog, with the characteristic asymmetric stepped case profile that protects the crown and pushers — a design inherited directly from the reference's mid-century ancestors. The 42mm diameter sits comfortably on a wide range of wrist sizes without overwhelming the wrist, a balance that has contributed enormously to the Speedmaster's universal appeal.

The white index dial is the defining character of this reference within the current Moonwatch lineup. Where the classic black dial references evoke the darkness of space and the drama of Apollo-era mission photography, the white dial introduces a cleaner, more contemporary palette that reads beautifully in daylight. Applied index hour markers provide clear legibility alongside the chronograph subdials, and the overall dial architecture retains every element of the canonical Moonwatch layout that enthusiasts and collectors recognize at a glance. The aluminum tachymeter bezel — a hallmark of the Moonwatch Professional — allows for speed calculations using the elapsed-time chronograph function, connecting this modern piece directly to its motorsport and aerospace origins.

The black rubber strap is a natural companion to the steel case and white dial, providing a sporty, versatile wearing experience that suits the Speedmaster's professional character. Rubber straps on Moonwatch references have grown in popularity among collectors who want a durable, comfortable alternative to the traditional bracelet, especially for active use or warm climates. The strap is designed to complement the case and dial aesthetics while offering the kind of wrist comfort that encourages everyday wear.

Powering the Speedmaster Moonwatch Professional is a manual-winding chronograph movement — the type of caliber at the core of every Moonwatch Professional — maintaining the hand-wound ritual that has been part of the Moonwatch experience since the collection's earliest days and that purists regard as an essential part of the ownership experience. Winding the crown each morning is a small ceremony that connects the wearer to a lineage of astronauts, test pilots, and explorers who trusted this watch in the most demanding conditions imaginable.
