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

“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.
