The four watch designs voted on by fans were all inspired by the ever-shifting colors of the sea and the flow of time from sunrise to sunset. Each design expressed one of four seascape scenes at a different time of day – sunrise, daytime, late afternoon, and sunset. In the end, the most-voted-for design was the one inspired by the seascape illuminated by daytime sunlight, expressed through a vibrant blue dial color inspired by the concept of “Daytime Blue.”

Inheriting the legacy of a 1965 classic

Powered by the automatic Caliber 6R55, the fan-selected limited edition is based on the original 1965 diver’s watch. Inheriting the legacy of Seiko’s original diver’s watch, the new creation features a timeless, purpose-driven design combined with modern functionality, including 300 meters of water resistance for air diving and a power reserve of approximately 72 hours.
Inspired by a daytime seascape

The dial and bezel colors showcase a daytime seascape, with the sea shining in vibrant blue as it reflects sunlight. The pattern draws inspiration from the wave mark and was originally used on two limited-edition models released to commemorate the 60th anniversary of the Seiko diver’s watch. The wave mark symbolizes the reliability and technological excellence that define Seiko’s diving heritage. Featured on the case back of the world’s first titanium 600m saturation diving watch introduced in 1975, it has appeared on the case back of Seiko diver’s watches ever since.

The back of the watch is marked “LIMITED EDITION” and includes the individual number out of 4,500.
