Omega Speedmaster Professional Moonwatch Hesalite

The Omega Speedmaster Professional Moonwatch stands as humanity's most significant horological achievement, remaining virtually unchanged since accompanying astronauts to the lunar surface in 1969. This reference preserves the authentic Moonwatch experience with its signature Hesalite crystal—the same shatter-resistant acrylic material chosen by NASA for its superior shock absorption qualities over sapphire. The domed crystal creates the distinctive vintage aesthetic while offering practical advantages: unlike sapphire, Hesalite won't shatter into dangerous fragments under extreme impacts, making it ideal for space missions and terrestrial adventures alike. The black dial features three contrasting sub-dials in the classic tri-compax layout: small seconds at 9 o'clock, 30-minute recorder at 3 o'clock, and 12-hour recorder at 6 o'clock, all activated by the legendary manual-winding Calibre 1861. This rhodium-plated descendant of the moon-worn Calibre 321 beats at 21,600 vibrations per hour, delivering 48 hours of power reserve through its cam-controlled chronograph mechanism. The 42mm stainless steel case with twisted lugs maintains the asymmetrical profile designed to protect the pushers and crown, while the black anodized aluminum bezel with tachymeter scale enables speed calculations—a reminder of the Speedmaster's racing origins. Each watch arrives in a special presentation box containing both a NASA-specification velcro strap and a NATO strap, along with tools and documentation celebrating the Moonwatch's extraordinary journey from racetrack to lunar surface. Our offering is very good condition and comes in full set of boxes and papers (not dated, not stamped). Covered by our limited warranty of 1 year, starting on the date of purchase.
