DESCRIPTION This watch takes its design cues from the original ‘Alpinist,’ first launched in 1959 exclusively in the Japanese market for Japanese ‘Yama-otoko’ mountain men, to be reliable in treacherous terrain. The 2021 version is designed for practicality – powered by the Automatic 6R movement with highly visible lumibrite on the dial and hands – easy to see in any light. Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.
