Seiko SEA Automatic Diver’s Seiko 145th Anniversary Limited Edition HBB001K1

The Seiko SEA Automatic Diver’s Seiko 145th Anniversary Limited Edition HBB001K1 celebrates Seiko’s 145-year heritage with classic dive watch styling and reliable mechanical performance. Limited to 9,999 pieces worldwide, this special edition combines the iconic Seiko Diver aesthetic with modern durability and comfort.

Its light-colored dial creates a striking contrast against the black unidirectional diving bezel, while LumiBrite-treated hands and indexes ensure excellent readability in low-light and underwater conditions.

Inside the 41.7 mm stainless steel case beats Seiko’s trusted 4R35 automatic movement, offering approximately 41 hours of power reserve and manual winding capability. With 200 meters of water resistance, a screw-down crown and diver’s bezel, the watch is built for active use.

A durable Hardlex crystal, magnetic resistance rated at 4,800 A/m and a stainless steel bracelet with diver extension complete the robust design. The numbered case back highlights the watch’s limited-edition status.
