The Prospex LX GMT U.S. Special Edition's dramatically graduated dial echoes the black and brown hues of the North America Nebula.
From the brand: Seiko Prospex challenges every limit with timepieces created to exceed expectations, engineered with superior style and innovative technology for the sea, sky or land. Driven by a heritage of iconic design, Prospex continues to keep going forward with excellence in precision timekeeping, crafted for the modern world.
This extraordinary Special 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 for 100 meters of water resistance. The matching titanium bracelet, also super-hard coated, secures with a tri-fold push button release clasp.
