SEIKO PROSPEX SPB451 1965 HERITAGE DIVER’S WATCH

Rooted in the design of Seiko’s first diver’s watch from 1965, the Prospex SPB451 brings a legendary silhouette into the modern era. Its compact 40 mm stainless-steel case, rich blue sunray dial, and coordinating unidirectional bezel create a confident presence that feels equally at home beneath the waves or above them.

Engineered for serious performance, this refined diver is powered by Seiko’s 24-jewel Caliber 6R55 automatic movement. It offers manual winding capability and an approximately 72-hour power reserve, giving you three full days of dependable operation.
