LIMITED EDITION OF ONLY 1300 PIECES!

Seiko automatic men's watch, model inspired by the 1968 diving watch. This watch was worn by members of the 63rd Japanese Antarctic Research Expedition. The case, bezel and crown are all in Seiko Ever-Brilliant steel. To ensure the durability of the watch, the crown is locked into a separate component integrated into the case. The watch is powered by caliber 8L35, which was developed specifically for diving watches and hand-assembled by the artisans of the Shizukuishi Watch Studio in northern Japan. The structured dial evokes the Antarctic landscape, while the subtle gradation of blue, from light to dark, echoes the beautiful colors of polar ice.
