Seiko Prospex ‘Deep Lake’ Alpinist 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. Its colour is inspired by those peaceful alpine lakes, found deep in the mountains. Designed for practicality, this latest version is powered by the Automatic 6R movement with highly visible lumibrite on the dial and hands - easy to see in any light - and 200m water resistance. 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.
