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. Meeting ISO standards for scuba diving to depths of up to 300 meters, this powerful saturation diver is crafted of light and durable titanium with a black super-hard coating for nearly doubled hardness and features a screwdown caseback and crown, as well as a black silicone strap. The rich black 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 a sapphire crystal with anti-reflective coating on the inner surface. 300m Water Resistant.
