Limited to 9,999 pieces worldwide, the HBB001K1 pairs the updated Samurai case platform introduced in 2024 with the \"Seiko Blue\" accent treatment that defines the entire 145th Anniversary series: a blue aluminium unidirectional rotating bezel, a blue seconds hand, and a silver-white dial that creates the clean, cool, distinctly modern presentation that has made the Seiko Blue series the standout aesthetic of the anniversary range.\u003c\/p\u003e\n\n\u003cp\u003eThe \"Samurai\" nickname — given by Seiko collectors for the angular, blade-like case surfaces that define the case shape's visual character — belongs to a platform that received a meaningful update in 2024: the case diameter came down to a more wearable 41.7mm, the thickness is 12.3mm slim, and the lug-to-lug at 49.5mm wears more comfortably than earlier Samurai generations. The chamfered centre links on the solid stainless steel bracelet reflect the same angular design language as the case, creating a unified aesthetic that runs from dial to clasp. Powered by the 4R35 automatic calibre with hand-winding and stop seconds, it delivers dependable everyday performance at Diver's 200M water resistance with Lumibrite on the hands, indexes, and bezel for complete low-light legibility.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSeiko 4R35 automatic movement with manual winding and stop seconds — dependable in-house mechanical performance\u003c\/li\u003e\n  \u003cli\u003eApprox. 41-hour power reserve — everyday diver's reliability\u003c\/li\u003e\n  \u003cli\u003eAccuracy: +45\/-35 seconds per day — reliable automatic timekeeping\u003c\/li\u003e\n  \u003cli\u003eDiver's 200M water resistance — professional dive specification\u003c\/li\u003e\n  \u003cli\u003eSilver-white dial — the clean, sophisticated 145th Anniversary Seiko Blue design language\u003c\/li\u003e\n  \u003cli\u003eSeiko Blue accent on rotating bezel and seconds hand — signature anniversary colour applied with restraint\u003c\/li\u003e\n  \u003cli\u003eBlue aluminium unidirectional rotating bezel — purpose-built for safe and accurate dive timing\u003c\/li\u003e\n  \u003cli\u003eLumibrite on hands, indexes, AND bezel — complete low-light legibility for diving use\u003c\/li\u003e\n  \u003cli\u003eHardlex crystal — reliable scratch resistance for active daily use\u003c\/li\u003e\n  \u003cli\u003e41.7mm stainless steel case — updated 2024 Samurai proportions at 12.3mm slim \/ 49.5mm lug-to-lug\u003c\/li\u003e\n  \u003cli\u003eScrew-down crown — water integrity protection for diving use\u003c\/li\u003e\n  \u003cli\u003eScrew caseback with \"LIMITED EDITION\" inscription — provenance marked\u003c\/li\u003e\n  \u003cli\u003eDate display — everyday practicality built in\u003c\/li\u003e\n  \u003cli\u003eStainless steel bracelet with chamfered centre links and three-fold clasp with extender — unified linear design language from case to clasp\u003c\/li\u003e\n  \u003cli\u003eMagnetic resistance 4,800 A\/m — protection in everyday environments\u003c\/li\u003e\n  \u003cli\u003eLimited to 9,999 pieces worldwide — confirmed global scarcity\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy You'll Love It\u003c\/h3\u003e\n\u003cp\u003eThe HBB001K1 is the 145th Anniversary Prospex diver for those who want the Seiko Blue commemorative treatment on the most angular and modern Samurai case platform to date. The blue bezel against the silver-white dial is a combination that reads as fresh and contemporary — less oceanic than the classic deep blue, more deliberate and design-forward than a standard stainless diver. The Lumibrite bezel is the functional detail that ties the aesthetics to the dive watch brief: the timing reference is legible in the dark. The updated 2024 Samurai proportions at 41.7mm and 12.3mm are the most wearable this case shape has been, and the chamfered bracelet centre links bring the linear design language to the wrist with a quality of finishing that justifies the anniversary designation.
