Inspired by Seiko’s 1968 Diver’s watch, the SPB383J1 is a modern evolution of Japan’s first hi-beat one-piece diving watch. Powered by the new Calibre 6R54, it’s Seiko’s first diving watch with mechanical GMT functionality. Built for comfort and durability, the bracelet features a low center of gravity for wearability and a ceramic diving scale for scratch resistance. With a three-day power reserve and 200m water resistance, this watch is perfect for professional and recreational divers.
