Omega Speedmaster 311.12.42.30.01.001

The Omega Speedmaster reference 311.12.42.30.01.001 represents a contemporary iteration of the legendary Moonwatch lineage, maintaining the essential DNA that made the Speedmaster the first watch worn on the lunar surface. This 43.5mm steel case model upholds the storied heritage of NASA s qualified timepiece while incorporating subtle modern refinements. The reference preserves the fundamental characteristics that collectors seek in a true Speedmaster: the manual-wind chronograph functionality, tachymeter bezel, and the classic proportions that have remained largely unchanged since the 1960s. As part of Omega s Professional collection, this reference continues the unbroken chain of Moonwatch heritage that spans over six decades of space exploration and motorsport timing. At its heart beats the manually-wound Caliber 1861, a descendant of the legendary Lemania-based movement that powered the original moon landing watches. This robust 18-jewel movement operates at 21,600 vibrations per hour and offers a 48-hour power reserve, maintaining the traditional mechanical chronograph architecture that collectors prize. The movement s proven reliability and serviceable design have made it a cornerstone of Omega s chronograph offerings. The black dial features the distinctive orange chronograph hand, creating visual contrast against the classic white subdials and indexes, while the fixed tachymeter bezel maintains the functional tool watch aesthetic that defines the Professional series. Design-wise, this reference showcases the hesalite crystal that enthusiasts often prefer over sapphire for its historical authenticity and the characteristic way it catches and diffuses light. The 50-meter water resistance and solid case construction ensure daily wearability while preserving the watch s tool watch credentials. From a collectibility standpoint, this reference occupies a significant position as a contemporary Moonwatch that maintains classical proportions and specifications, making it highly sought after by both Speedmaster specialists and broader mechanical chronograph collectors. The orange accent hand adds a distinctive visual signature that sets it apart from standard production models, while the overall execution remains true to the fundamental Speedmaster design language that has captivated collectors worldwide.
