In celebration of Seiko’s 145th anniversary,
Seiko Prospex introduces a limited-edition model with blue accents inspired by “Seiko Blue.”

In the second series of commemorative limited-edition watches celebrating Seiko’s 145th anniversary, a blue accent inspired by “Seiko Blue” is used. Established in the 1960s and refined over time, Seiko Blue continues to embody the Seiko brand identity.

“Seiko Blue,” a signature color established in the 1960s and perfected over the decades, inspires the watch’s blue bezel insert and seconds hand.

The case design, inspired by Japan’s first diver’s watch from 1965, embodies a compact, sophisticated, and iconic style. The combination of blue bezel and a silver white dial creates a fresh and sophisticated impression on the wrist.
