Limited to 500 pieces, this reference SNR045 Spring Drive Diver honors Seiko's original saturation dive watch from 1968. The watch also honors the role of Seiko timepieces as essential equipment for the Japanese Antarctic Research Expedition (JARE) in its daring explorations of such regions as the Skarvsnes, whose underwater forests inspired the green tones of this distinctive watch's patterned dial and ceramic bezel. Upgraded with the latest technology, this exceptional timepiece is powered by a 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 a power reserve of approximately 72 hours, the movement can be wound manually or automatically. Crafted of light and durable titanium with a super-hard coating for nearly doubled hardness, this superbly reliable watch features a screwdown caseback and crown, as well as a tri-fold push button release clasp with secure lock and slide adjuster. The dial, framed by a one-way rotating elapsed timing bezel, includes a power reserve indicator, date calendar and LumiBrite hands and markers, and is topped by an anti-reflective sapphire crystal.

Designed for those who treat life as the ultimate adventure, the Seiko Prospex LX collection 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.
