Seiko Prospex Speedtimer Solar Chronograph SFJ003

Prospex Speedtimer 1/100 Second 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. Featuring the new solar chronograph 8A50 movement, this exceptional watch further advances the high-intensity collection with inspiration from Seiko's - and the world’s - first analog quartz chronograph, which featured a 1/100-second stopwatch. For enhanced legibility, the uniquely designed dial includes a black base with four black inset subdials, separating the time dial from the chronograph indicators, and LumiBrite hands and markers. The chronograph function measures up to 60 minutes of elapsed time in 1/100-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. To allow easy utilization of the stopwatch feature, this precision watch features concave tops on the hammer-shaped pushers. With a curved anti-reflective sapphire crystal, this rugged stainless steel timepiece includes a screwdown caseback and tri-fold push button release clasp. 10 bar, 100M Water Resistant
