1970 HERITAGE DIVERS

SEIKO PROSPEX SPB301 SAVE THE OCEAN SPECIAL EDITION

An exceptional expression of Seiko’s diving heritage, the Prospex SPB301 reimagines the celebrated 1970 diver’s watch through an elegant Arctic lens. Its sculptural stainless-steel case retains the iconic recessed crown at 4 o’clock, a design originally conceived to protect the crown while improving safety beneath the surface.

The pressed white dial evokes the fractured beauty and quiet depth of polar ice, contrasted by a rich blue unidirectional bezel. More than a striking collector’s piece, this Special Edition supports Seiko’s Save the Ocean campaign, dedicated to marine conservation and the preservation of the waters that inspire it.

Inside, the 24-jewel Caliber 6R35 automatic movement delivers an approximately 70-hour power reserve and can also be wound manually. A curved sapphire crystal, super-hard case coating, and 200-meter water resistance complete a timepiece created for serious exploration and distinguished by rare visual character.
