Product details Seiko Diver’s Watch 60th
Anniversary Limited Model Special Site Seiko’s diver’s watch celebrates its 60th anniversary this year. The first domestically produced diver’s watch, released in 1965, was used as equipment for wintering expeditions to the Antarctic expedition four times. Also, in 1968, a 10-vibration high-beat 300m air diving model, the world’s highest standard at the time, was introduced. Mr. Naoki Uemura and Mr. Teruo Matsuura of the Japan Alpine Club carried it with them when they climbed Everest. Furthermore, in 1975, we released the world’s first 600m saturation diving (*1) model with a titanium case, and have continued to innovate and evolve. This product is based on a historical model that reflects these historical milestones, and has evolved in both function and design to be appropriate for the 60th anniversary. 《Product Features》 Flagship model of “Marine Master” equipped with Seiko’s highest-end movement “Marine Master” is a high-end diver’s watch that brings together the technology and know-how that Seiko has cultivated while developing diver’s watches. Its appeal lies not only in its outstanding performance, but also in the sophisticated beauty of its exterior design and the exquisite finish in every detail.

Furthermore, by adopting a movement fixing method that can withstand diver’s watches, its robustness is further strengthened and the watch is designed to withstand harsh underwater environments. The power spring is made from Seiko’s proprietary alloy material Spron. This alloy, which has been independently improved by Seiko with the aim of being “no wear, no rust, no fatigue,” boasts durability and excellent quality. These technological innovations have made it a shoe that can be worn not only for professional use or active situations that require precision and durability, but also for a busy daily lifestyle. A dial with an unprecedented sense of depth and glossy texture that expresses the mystery of the deep sea.

Seiko’s diver’s watches have an integrated dial and index that are three-dimensionally molded, so the index will not fall off even if it is subjected to a strong impact. This time, as a new attempt, we covered the dial surface with thick transparent paint and carefully polished it, creating an unprecedented sense of depth and glossy texture. Furthermore, combined with the blue gradation color that deepens towards the outer edge of the dial, the entire dial expresses the mysterious and beautiful world of the deep sea that only professional divers can see. An authentic diver’s watch that is waterproof for 600m saturation diving and has evolved into a sophisticated appearance
