Prospex Speedtimer 40th Anniversary 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. This extraordinary Limited Edition, available only in a controlled-production run of 4,000, with the serial number engraved on each caseback, celebrates the 40th anniversary of the first analog quartz chronograph equipped with a 1/100-second stopwatch. Featuring the new solar chronograph 8A50 movement, this exceptional watch includes a highly legible, uniquely designed dial with a warm charcoal gray base and four inset black 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 stylish black center links, a screwdown caseback and tri-fold push button release clasp. 10 bar, 100M Water Resistant
