The AL4575X1 is a compelling example of design migration from Seiko's main Prospex line to its accessible sub-brand, Alba. The watch is directly inspired by the aggressive, shrouded case architecture of the iconic Seiko "Monster" series. As a subsidiary of Seiko, Alba leverages proven mechanical movements, and this model is powered by the calibre Y676, an unbranded version of Seiko's own robust 7S26 automatic calibre.
Established by the Seiko Watch Corporation in 1979, Alba functions as a strategic sub-brand focused on accessible, design-driven timepieces. The brand’s primary strength lies in its ability to leverage Seiko's proven, in-house mechanical calibres—such as the Y676 (7S26)—and established design DNA, often seen in models inspired by the Prospex "Monster" and "Tuna" series. Alba successfully translates its parent company's principles into a highly competitive, entry-level price point, serving as a practical gateway for new enthusiasts, particularly in Asian and Middle Eastern markets.
