Product Description
Seiko Prospex Automatic Diver – Special Edition "Night Ocean"
Tradition meets innovation – the icon among diving watches
The Seiko Prospex Automatic Diver Special Edition is a tribute to Seiko's first diving watch from 1965 – a watch that not only made Japanese watch history but also set international standards in reliability and functionality. This modernized version stays true to the classic original design while being equipped with state-of-the-art technology and high-quality materials.
Historical heritage – The first Japanese diving watch
In 1965, Seiko presented Japan's first diver's watch with an automatic caliber and a water resistance of 150 meters – a milestone that proved indispensable during the Japanese Antarctic Expedition (1966–1969). At that time, when precise time measurement was essential for astronomical observations, the Seiko diver's watch proved itself even under the most extreme conditions.
Special Edition 2018 – The Best of Two Worlds
The Prospex Special Edition from 2018 is strongly based on the legendary original from 1965, but sets new standards in terms of technology:
-
Automatic movement caliber 8L35 – developed and assembled in Seiko's famous Shizukuishi watch studio, offers outstanding precision and reliability.
-
Authentic design – sharply drawn hour markers remain harmoniously integrated into the dial.
Robustness and resilience – For true adventurers
The Seiko Prospex Night Ocean is specially designed for demanding diving missions and extreme conditions:
-
Zirconia ceramic bezel – extremely scratch- and shock-resistant
-
Hard-coated stainless steel case – additional protective layer against wear
-
Anti-reflective sapphire crystal – best readability even in strong sunlight
-
Water resistance up to 200 meters – professional diving watch according to ISO standard
Comfort and versatility
The watch comes with two high-quality straps:
-
Hard-coated stainless steel band with dive band extension – perfect for use over the wetsuit
-
Silicone band – light, flexible and ideal for all water adventures
Conclusion – The perfect diving watch
The Seiko Prospex Night Ocean Special Edition combines iconic design with state-of-the-art technology and unparalleled durability. It is the ideal companion for professional divers, adventurers, and anyone looking for a reliable watch for demanding missions.
Seiko Prospex Night Ocean – THE watch for divers and explorers.
