The year 2025 marks the 60th anniversary of the Seiko diver’s watch. Since creating Japan’s first diver’s watch in 1965,
Seiko has continuously advanced in diver’s watchmaking to meet the demands of professional divers worldwide.
Seiko’s first diver’s watch pursued reliability and safety, paving the way for many future innovations. In 1968,
the company released a high-beat, 300m air-diving model, meeting the global standard for the time.
In 1975, Seiko launched the world’s first 600m-water-resistant model for saturation diving and used a robust titanium case,
earning the trust of professional divers.
Since then, Seiko has continued to combine its unique technology and expertise to create numerous innovative diver’s watches
that have been loved by adventurers and explorers, proving their reliability in harsh environments around the globe.
Based on historical models reflecting Seiko’s significant milestones, three new 60th-anniversary limited editions demonstrate
how the Seiko diver’s watch has evolved in both functionality and design.
The Marinemaster is a high-end diver’s watch that embodies the technology and expertise Seiko has developed in creating diver’s watches.
Its appeal lies not only in its exceptional performance but also in the refined beauty of its exterior design and the meticulous finishing of its details.
The flagship model, the Marinemaster Professional, is designed to meet the more specialized and tough demands of professional divers.
Since the release of the first professional model in the Seiko diver’s watch lineup in 1968,
it has been essential to balance both the functional prowess as a tool and the aesthetic appeal as an accessory.
The 60th-anniversary limited edition model, equipped with the newly developed Caliber 8L45 mechanical movement,
achieves unprecedented beauty and performance and is now available from the Marinemaster series.
