Prospex 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. Following last year’s successful limited edition, this rugged and stylish watch is part of a high-intensity collection inspired by the 1969 “Speedtimer,” the world’s first self-winding chronograph. Paying tribute to the iconic original with its two-tone gray and black aluminum tachymeter bezel and seconds markers positioned on the dial ring for a cleaner and clearer dial, this exceptional timepiece offers an enhanced emphasis on usability, legibility and visibility by adding LumiBrite hands and markers, a slightly larger case size and a tapered three-link bracelet. 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 silver dial, in a brilliant sunray finish, features three black subdials, with a 24-hour indicator and power reserve indicator, as well as a date calendar and red chronograph hand. Crafted of stainless steel, with a curved anti-reflective sapphire crystal, secure screwdown caseback and tri-fold push button release clasp.  10 bar, 100M Water Resistant.
