Seiko 145th Anniversary Limited Edition
Limited edition of 9,999 pieces

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.

Inspired by “Seiko Blue,” a signature colour established in the 1960s and perfected over the decades, blue is adopted as an accent colour for the bezel and seconds hand.
The combination of the two-tone bezel and a silver white dial creates a fresh and sophisticated impression on the wrist.

This model inherits a case design composed of straight, blade-like surfaces, while achieving a sharper and more compact form. With chamfering on the centre links, the high-quality, solid bracelet delivers a refined finish that complements the case’s linear design.
