Designed for those who treat life as the ultimate adventure, Seiko Prospex keeps moving forward, meeting every challenge with technological excellence and winning design. This dramatic watch is part of a high-intensity collection inspired by the 1969 "Speedtimer," the world's first self-winding chronograph, extending it to the Black Series. Featuring Seiko’s "Green LumiBrite Pro," developed by combining the color most recognizable in the dark with a higher brightness and longer afterglow, this extraordinary timepiece provides a "night vision" experience for visibility in the dark resembling the view seen through a night scope. The chronograph function measures up to 60 minutes of elapsed time in 1/5-second increments and includes a split time function, while the solar cell, powered by any light source, with no battery change required, provides a 6-month power reserve when fully charged. The dark gray dial features 3 black subdials, and includes a 24-hour indicator and power reserve indicator, as well as a date calendar and green LumiBrite hands and markers. Crafted of stainless steel with black hard coating paired with a black combination nylon/ leather strap, it also includes a curved anti-reflective sapphire crystal, black tachymeter bezel, and a secure screwdown caseback. 10 bar, 100M Water Resistant.
