Seiko Prospex 145th Anniversary Limited Edition – Seiko Blue
Celebrating 145 Years of Seiko Heritage
In celebration of Seiko’s 145th anniversary, the Seiko Prospex collection introduces a special limited-edition timepiece inspired by the iconic Seiko Blue — a signature color that has represented the brand’s identity since the 1960s.
Combining timeless design with professional dive-watch functionality, this commemorative model features striking blue accents on the bezel and seconds hand, complemented by a crisp silver-white dial. The two-tone bezel adds depth and character, creating a fresh, sophisticated look that pays tribute to Seiko’s rich watchmaking heritage.
The stainless steel case showcases clean, blade-like surfaces and a sharper, more compact profile. Its solid stainless steel bracelet features carefully chamfered center links, delivering a refined finish that complements the case’s angular design.
Powered by the reliable Seiko Caliber 4R35 automatic movement, this limited-edition Prospex offers dependable mechanical performance alongside practical features designed for everyday wear and underwater adventures.
With 200-metre water resistance, a unidirectional rotating bezel, and a screw-down crown, this anniversary model combines distinctive styling with the robust functionality expected of a professional-inspired dive watch.
