SEIKO PROSPEX SPB379J1 ALPINIST AUTOMATIC MEN WATCH
Inspired by the original 1959 Seiko “Alpinist” created for Japanese mountain men, the Seiko Prospex SPB379J1 brings modern engineering to a timeless design. Built for adventurers, this automatic GMT timepiece features the in-house 6R54 calibre — Seiko’s first Prospex mechanical GMT with a 3-day power reserve — capable of tracking two time zones simultaneously.
Designed with legibility and functionality in mind, the SPB379J1 sports bold Arabic numerals, a red GMT hand, and a 24-hour scale on the inner bezel for quick reference. A curved sapphire crystal enhances visibility, while a screw-down crown and stainless steel case with super-hard coating ensure durability on rugged terrains. The compass bezel adds directional utility for the outdoors.
With 200m water resistance, magnetic resistance of 4,800 A/m, and LumiBrite on hands and indexes, this Alpinist evolution remains a reliable partner for explorers and professionals alike — staying true to the Prospex spirit: Professional Specifications for Adventure.
