Prospex Speedtimer Solar Chronograph Limited Edition. Designed for those who treat life as the ultimate adventure, Seiko Prospex keeps moving forward, meeting every challenge with technological excellence and winning design. Available only in a limited edition of 10,000, this exceptional watch, part of the high-intensity collection inspired by the 1969 “Speedtimer,” the world’s first self-winding chronograph, is designed for usability, legibility and visibility. The chronograph function measures up to 60 minutes of elapsed time in 1/5-second increments and provides a split time function, while the solar cell, powered by any light source, with no battery change required, offers a 6-month power reserve when fully charged. Framed by a black tachymeter bezel, the pale blue dial, with a brilliant sunray finish, features three black subdials, with a 24-hour indicator and power reserve indicator, as well as a date calendar and LumiBrite hands and markers. With a curved anti-reflective sapphire crystal, this rugged stainless steel timepiece includes stylish black hard-coated center links, as well as the security of a screwdown caseback and tri-fold push button release clasp. 10 bar, 100M Water Resistant
