Introducing an entirely new Prospex watch collection, inspired by Seiko’s professional timekeeping heritage. This timepiece is inspired by the flowing lines of the 1969 world’s first automatic chronograph watch.The latest version is conveniently solar-powered; the watch charges from both natural and electric light. Becoming official timekeeper for Tokyo’s high profile international sports event in 1964 was a turning point in Seiko’s history. Making precisely accurate professional timing instruments, with no prior experience, resulted in the Seiko Watch Corporation design code of visibility, legibility and functionality. Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ These timepieces are designed to be practical, reliable and durable within extreme or everyday environments, for experts, sports lovers and adventure seekers alike.
