The Seiko Speedtimer Solar Chronograph, part of the Prospex collection, is a rugged yet stylish timepiece crafted for adventurers. Inspired by the iconic 1969 “Speedtimer,” it features a striking two-tone blue and red aluminum tachymeter bezel and a clean, legible dial with seconds markers on the dial ring. The brilliant blue sunray-finished dial includes three black subdials, a 24-hour indicator, power reserve indicator, date calendar, and a bold red chronograph hand. Enhanced with LumiBrite hands and markers, a larger case size, and a tapered three-link bracelet, it prioritizes usability and visibility. 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. Built from stainless steel with a curved anti-reflective sapphire crystal, screwdown caseback, and water resistance up to 100M, this watch combines durability, innovation, and timeless design.
