Seiko Limited Edition 145th Anniversary Prospex Diver HBB001K

Celebrate Japanese watchmaking heritage with the Seiko Prospex 145th Anniversary Limited Edition Men’s Automatic Watch HBB001K, a bold and collectible diver’s timepiece limited to just 9,999 pieces worldwide. 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.

What we love about the Seiko Prospex HBB001K is how it brings together Seiko’s Japanese heritage, professional dive-watch functionality, and anniversary-edition collectability in one confident design.
