This model is a modern interpretation of the first generation Alpinist, which was developed for mountaineering and appeared in 1959, which became the pioneer of Seiko sports watches. The watch is water resistant to 20 bar, which can be worn outdoors without stress, and Lumibrite, which ensures visibility in dark places, is used for the hour, minute, second hands and abbreviations. It features a navy and brown stamped dial that evokes the rich water sources stored in the mountains and the thick trees.
