This timepiece is part of the Alpinist collection, first launched in 1959 exclusively for the Japanese market. Hugely popular with many fans around the world, these new designs are now available worldwide with an updated specification from their original inspiration: a longer 70-hour power reserve and an upgrade of the glass to sapphire crystal. Seiko Prospex watches are designed for sports lovers and adventure seekers on the water, in the sky or on land. This watch is from the Land category and features a bracelet and a beautiful brown dial similar to the original piece. Since the launch of the first Japanese diving watch in 1965, Seiko's innovative watchmaking has changed the global standards of diving watches.
