SPB453J1
The Seiko Prospex SPB453J1 is a modern re-interpretation of Seiko’s very first diver’s watch from 1965. Featuring a sleek 40mm stainless steel case with super-hard coating and a curved sapphire crystal, this watch is engineered for both underwater reliability and daily wear comfort.
Powered by the Caliber 6R55 automatic movement, it offers an impressive 72-hour power reserve. The black dial is accented with Lumibrite on the hands and markers for enhanced visibility, while the 300m water resistance and ISO certification make it a professional-grade dive watch.
Designed with a slimmer case profile, shortened lugs, and an upgraded clasp for improved fit and durability, the SPB453J1 blends heritage and high performance.
