Inspired by the 1965 original – Seiko’s first-ever diver’s watch – the Prospex SPB453J1 is reimagined for the modern age with enhanced performance and refined style. Its 40mm stainless steel case houses a curved sapphire crystal, while a black dial with Lumibrite-coated hands, indexes, and bezel ensures superb legibility even in the depths of the ocean.

Engineered for serious underwater exploration, the SPB453J1 is equipped with a screw-down crown, unidirectional rotating bezel, and 300m water resistance. The Calibre 6R55 automatic movement offers a robust 72-hour power reserve, combining heritage design with today’s watchmaking innovations. With a slim profile and secure three-fold clasp, this timepiece is equally suited for diving and everyday wear.
