What to know
The HBB001 is the more angular of Seiko’s two blue-accented Prospex editions celebrating the company’s 145th anniversary. A silver-white dial is framed by a two-tone aluminium bezel: silver for the first 15 minutes and blue for the remaining scale. Faceted lugs and chamfered bracelet links reinforce the watch’s crisp, sculpted character.
Inside is automatic calibre 4R35, with hand winding, a date display and roughly 41 hours of power reserve. The 41.7mm steel case is 12.3mm thick, uses Hardlex crystal and is rated as a 200-metre diver. Seiko limits production to 9,999 pieces and listed a European recommended price of €650.
