Omega Speedmaster Professional 311.30.42.30.01.005 – The Legendary Moonwatch, Caliber 1861, 42mm Stainless Steel

Few timepieces carry the same historical status and enduring appeal as the Omega Speedmaster Professional Moonwatch, and reference 311.30.42.30.01.005 represents one of the most authentic modern iterations of the watch worn during NASA’s Apollo lunar missions. This model maintains the essential design features that made the original Moonwatch an icon, blending space-tested engineering with timeless style.

The watch features Omega’s signature 42mm stainless steel case, an asymmetrical design introduced in 1964 that includes twisted lyre lugs and integrated crown guards for improved durability. A classic Hesalite crystal—the same material specified by NASA for safety reasons—covers the dial, offering a warm, vintage aesthetic while preserving the original Moonwatch character. The black aluminum tachymeter bezel frames a crisp matte black dial with luminous white baton hour markers, providing excellent contrast and legibility in all lighting conditions. The layout includes three recessed subdials: a 30-minute chronograph counter at 3 o’clock, a 12-hour counter at 6 o’clock, and a running seconds register at 9 o’clock. White baton hands with Super-LumiNova application maintain visibility while preserving the classic utilitarian styling. The watch is fitted with a brushed and polished stainless steel Speedmaster bracelet, complementing its rugged yet refined appearance. The look is completed by a solid engraved caseback bearing the classic inscriptions: “Flight-Qualified By NASA For All Manned Space Missions” and “The First Watch Worn On The Moon.”
