Designed for those who treat life as the ultimate adventure, Seiko Prospex continues to advance, facing every challenge with exceptional technology and winning design. This dramatic timepiece is part of the High Intensity Collection, inspired by the 1969 Speedtimer, the world's first automatic chronograph, and has been expanded to include the Black Series. Featuring Seiko's Green LumiBrite Pro, developed to combine the most visible color in the dark with higher brightness and longer afterglow, this exceptional timepiece offers a "night vision" experience for visibility in the dark, similar to the view through a night scope. The chronograph function measures elapsed time up to 60 minutes in 1/5-second increments and includes a split-time function. The solar cell is powered by any light source, never requires replacement, and provides a six-month power reserve when fully charged. The dark gray dial features three black subdials displaying the 24-hour and power reserve indicators, a date calendar, and green LumiBrite. It features Brite hands and markers, is crafted from black hard-coated stainless steel and is presented on a black combination nylon/leather strap, and also includes a curved anti-reflective sapphire crystal, a black tachymeter bezel, and a secure screw-down caseback.
