Seiko Speedtimer Solar Chronograph. 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.

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. Framed by a black tachymeter bezel, the green sunray dial features 24-hour and power reserve indicators, as well as a date calendar and LumiBrite on the hands, markers and the tip of the chronograph hand. Crafted of stainless steel, this timepiece includes a curved anti-reflective sapphire crystal, secure screwdown caseback and tapered three-link bracelet with tri-fold push button release clasp. 10 bar, 100M Water Resistant
