SEIKO SPOTLIGHT
SPB451J1
A modern revival of Seiko’s legendary 1965 dive watch, the Seiko Prospex SPB451J1 blends heritage with cutting-edge performance. Crafted from stainless steel with a super-hard coating, this diver’s watch features a striking Scuba Blue dial accented with LumiBrite for enhanced visibility in low light. The 40mm case is fitted with a curved sapphire crystal, screw-down crown, and unidirectional rotating bezel—ensuring professional-grade dive functionality.
Powered by the upgraded Calibre 6R55 movement, this timepiece offers a robust 72-hour power reserve and water resistance of up to 300 metres. With refined finishing, classic proportions, and modern endurance, the SPB451J1 is a true tribute to Seiko’s dive watch legacy.
