The Seiko Speedtimer Solar Chronograph, part of the Prospex collection, is designed for adventurers who value both style and performance. Inspired by the iconic 1969 “Speedtimer,” it features a two-tone gray and black aluminum tachymeter bezel and a clean, legible dial with LumiBrite hands and markers. The silver sunray-finished dial includes three black subdials, a 24-hour indicator, power reserve indicator, date calendar, and a striking red chronograph hand. Powered by a solar cell, it offers a 6-month power reserve and a chronograph function measuring up to 60 minutes in 1/5-second increments with a split time feature. Crafted from stainless steel with a curved anti-reflective sapphire crystal, screwdown caseback, and tapered three-link bracelet, it’s water-resistant up to 100M, combining rugged durability with timeless design.
