A Tribute to Spring Drive in Space

This extraordinary Seiko Prospex LX Spring Drive GMT US Exclusive Edition is inspired by the North America Nebula, a spectacular formation approximately 2,000 light years from earth. The impressive dial has a dramatic color gradation, evoking the diffuse nebula with the tones of brown deepening to black as the formation fades into the darkness of space. Framed by a glossy dual-tone sapphire bezel, this phenomenal dial is complemented by a rose-gold tone GMT hand and includes a power reserve indicator, date calendar, and LumiBrite hands and markers. Providing exceptional precision, the Spring Drive GMT boasts a 30-jewel automatic winding movement that powers a quartz regulator, resulting in an astounding accuracy of +/- 1 second per day, +/- 15 seconds per month while remaining fully mechanically driven. Offering a power reserve of approximately 72 hours, with manual winding capability, the movement is equipped with a GMT function that allows tracking of a second time zone at a glance. Crafted of light and durable titanium with a super-hard coating and rose gold accents, this finely finished watch features a sapphire crystal with super-clear coating, for the ultimate in clarity, as well as a screwdown caseback and crown, and a tri-fold push button release clasp. 

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.
