Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to celebrate a long history of sports watch excellence with recreations and reinterpretations of landmark achievements.

This new Seiko Prospex LX Spring Drive GMT 'Sky' Limited Edition highlights Seiko's past and present feats, with a design inspired by Seiko's revolutionary 1968 professional diver's watch, but powered by a fully modern Seiko Spring Drive movement, combining a 30-jewel automatic movement with a quartz regulator for accuracy to +/- 1 second per day, +/- 15 seconds per month. With the Spring Drive movement tested for precision by astronaut Richard Garriott on the International Space Station, this limited edition also pays tribute to space exploration with the blue and black gradated dial and sapphire bezel ring evoking the stratospheric boundary of the Earth's sky and outer space.
