Prospex LX Collection. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line follows every challenge with technological excellence and style. Powered by a Seiko Spring Drive movement, this precision timepiece combines 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 rich black dial, framed by a rotating compass bezel, includes yellow accents, a power reserve indicator, date calendar, yellow GMT 24-hour hand, and LumiBrite hands and markers, and is topped by a sapphire crystal with super-clear coating. 20 bar, 200M Water Resistant.
