SEIKO PROSPEX
SEIKO WATCH AUTOMATIC PROSPEX SEA 145TH ANNIVERSARY LIMITED EDITION JDM 41.7MM HBB001K1
The Seiko Prospex HBB001K1 is the "Samurai" in Seiko's second wave of 145th Anniversary commemorative limited editions. Limited to 9,999 pieces worldwide, the HBB001K1 pairs the updated Samurai case platform introduced in 2024 with the "Seiko Blue" accent treatment: a blue aluminium unidirectional rotating bezel, a blue seconds hand, and a silver-white dial.
The "Samurai" nickname belongs to a platform that received a meaningful update in 2024: the case diameter came down to a more wearable 41.7mm. 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.
