Created in honour of Seiko’s 145th anniversary, this Prospex model showcases the brand’s enduring commitment to precision engineering, durability, and high-quality Japanese manufacturing.

Inspired by the iconic “Seiko Blue” first established in the 1960s, this limited-edition men’s watch features striking blue accents on the bezel and seconds hand, delivering a distinctive commemorative look that reflects Seiko’s rich history and refined design language.

Built for performance and everyday confidence, this Seiko Prospex automatic watch combines professional dive capability with a sharp, masculine aesthetic. The fresh silver-white dial is enhanced by bold LumiBrite hands, markers, and bezel details for excellent visibility in underwater and low-light conditions, while the robust stainless steel case and bracelet provide strength, comfort, and long-lasting wear. Its compact yet powerful 41.7mm case features straight, blade-like surfaces for a modern Prospex profile, complemented by chamfered centre bracelet links for a premium finish on the wrist.

Powered by Seiko’s reliable Calibre 4R35 automatic movement with manual winding capability, the HBB001K offers approximately 41 hours of power reserve, 23 jewels, a stop-seconds function, and a practical date display. Designed for serious use, this men’s Seiko diver’s watch features 200 metres water resistance, a screw-down crown, screw case back, unidirectional rotating bezel, Hardlex crystal, magnetic resistance of 4,800 A/m, and a secure three-fold clasp with push button release and extender.

The case back is marked “LIMITED EDITION,” reinforcing its collectible status and connection to Seiko’s landmark anniversary.
