Prospex Speedtimer Solar Chronograph U.S. Special 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 rugged and stylish watch is a part of a high-intensity collection inspired by classic motorsports in the 1970s, when Seiko’s original 1969 “Speedtimer,” the world’s first self-winding chronograph, was at its prime. Offering a bright red tachymeter bezel for a bold pop of color, this exceptional timepiece showcases a silvery white dial with high contrast subdials for an eye-catching look. 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 dial also features a 24-hour indicator and power reserve indicator, as well as a date calendar, and LumiBrite hands and markers. Crafted of stainless steel, this sporty model also includes a curved anti-reflective sapphire crystal, secure screwdown caseback, tri-fold push button release clasp, and an additional perforated black leather strap. 10 bar, 100M Water Resistant
