From the
Collection
The Seiko Prospex LX Sky U.S. Special Edition celebrates humanity's connection to space with a timepiece as technically ambitious as the astronauts who've worn Spring Drive movements aboard the International Space Station.
The 44.8mm titanium case receives Zaratsu polishing, creating mirror-like surfaces that catch light with Grand Seiko-level refinement. A textured gray dial evokes the lunar surface, while the two-tone sapphire GMT bezel transitions from light to shadow like moonlight across craters.
Inside beats the caliber 5R66, Seiko's remarkable Spring Drive GMT movement that marries mechanical soul with quartz precision. This 30-jewel automatic achieves accuracy within one second per day through its Tri-synchro Regulator system, which uses electromagnetic regulation to create the movement's signature glide motion seconds hand. The 72-hour power reserve proves generous for a movement this precise, while the independently adjustable GMT hand makes this a true traveler's watch. Blue accents on the GMT hand and power reserve indicator add a thoughtful reference to Earth as seen from orbit.
The super-hard coating applied to both case and sapphire crystal enhances scratch resistance well beyond standard titanium, while maintaining the metal's exceptional comfort on the wrist. At 100 meters of water resistance, this watch bridges the gap between Seiko's legendary dive watch heritage and its space-age horological innovation.
