The Seiko Prospex Diver's 145th Anniversary HBB001K Limited Edition celebrates Seiko’s 145th anniversary with a refined design inspired by the iconic “Seiko Blue” — a signature colour that has represented the brand since the 1960s. The fresh silver-white dial is paired with striking blue accents on the bezel and seconds hand, creating a sophisticated and modern aesthetic on the wrist. Limited to just 9,999 pieces worldwide, this special edition combines heritage-inspired styling with dependable dive watch performance. Powered by the automatic Calibre 4R35 movement, the watch is driven by the movement of the wearer and offers reliable everyday precision. The 41.7mm stainless steel case features sharp, blade-like surfaces with a more compact profile, while the solid stainless steel bracelet with chamfered centre links delivers a premium and comfortable fit. Finished with durable Hardlex glass and 200 metres of water resistance, this Prospex diver is built for both adventure and everyday wear. - Calibre 4R35 - Automative Movement - Powered by the movement of the wearer - 41.7mm Case Size - 12.3mm Case Thickness - Stainless Steel Case and Bracelet - Hardlex Glass - 200 Meters Water Resistant
