Seiko Prospex

Limited Edition 145th Anniversary Silvertone “Samurai” Diver’s Watch

Celebrate Seiko’s 145th Anniversary with the HBB001K1, a striking limited edition from the Prospex collection, commemorating the brand’s beginnings as a Tokyo clock and watch repair shop in 1881. This timepiece features the iconic ‘Samurai’ design, beloved by Seiko enthusiasts for its sharp, angular case that evokes the precision of a Japanese Samurai sword. Built for both collectors and adventurers, this watch blends heritage, style, and performance in a single bold package.

Designed for professional diving, the HBB001K1 offers 200 meters of water resistance, a silver dial enhanced with LumiBrite on the hands and indices for exceptional visibility in low-light conditions, and a unidirectional aluminium bezel for safe timing underwater. The second hand and bezel are highlighted in a striking ‘Seiko Blue,’ adding a touch of dynamic color to the timepiece. Each watch also features a special limited edition engraving on the case back, emphasizing its exclusivity.

As part of the Seiko Prospex line—short for “Professional Specifications”—this watch delivers durability, practicality, and reliability for extreme environments. Whether exploring the depths of the ocean or enjoying everyday adventures, the HBB001K1 combines precision engineering with iconic design, making it an essential timepiece for sports lovers, divers, and collectors alike.
