Seiko Prospex LX 400 Piece Limited Edition Blue SNR049 Sky GMT 45mm Spring Drive

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. Crafted of light and durable titanium with a super-hard coating for nearly doubled hardness, this superbly reliable watch features a sapphire crystal with super-clear coating, and a screwdown caseback and crown, as well as a tri-fold push button release clasp. The movement, with a power reserve of approximately 72 hours, can be wound manually or automatically. Framed by a rotating GMT bezel, the dial includes a power reserve indicator, date calendar, blue GMT hand, and LumiBrite hands and markers. Water-resistant to 10 bar, 100 meters (330 feet)
