Seiko Prospex Automatic Diver – Special Edition "Night Ocean"

Tradition meets innovation – the icon among dive watches

The Seiko Prospex Automatic Diver Special Edition is a tribute to Seiko’s first dive watch from 1965 – a watch that not only made Japanese watch history but also set international standards for 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 dive watch

In 1965, Seiko introduced Japan’s first dive watch with an automatic caliber and water resistance of 150 meters – a milestone that proved indispensable during the Japanese Antarctic Research Expedition (1966–1969). At a time when precise timekeeping was essential for astronomical observations, the Seiko dive watch performed reliably even under the most extreme conditions.

Special Edition 2018 – The best of both worlds

The 2018 Prospex Special Edition is strongly inspired by the legendary original from 1965 but sets new standards in technology:

• Automatic caliber 8L35 – developed and assembled in Seiko’s renowned Shizukuishi watch studio, offering outstanding precision and reliability.
• Authentic design – sharply defined hour markers remain harmoniously integrated into the dial.

Durability 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 – excellent readability even in strong sunlight
• Water resistance up to 200 meters – professional dive watch according to ISO standard

Comfort and versatility

The watch comes with two high-quality straps:

• Hard-coated stainless steel bracelet with dive extension – perfect for wearing over a wetsuit
• Silicone strap – lightweight, flexible, and ideal for all water adventures

Conclusion – The perfect dive watch

The Seiko Prospex Night Ocean Special Edition combines iconic design with cutting-edge technology and unmatched durability. It is the ideal companion for professional divers, adventurers, and anyone seeking a reliable watch for demanding missions.
