Introducing the Prospex 1965 Heritage Diver’s Watch Series

The latest iteration of Seiko's Prospex 1965 Heritage Diver’s Watch series features three references, including a special edition commemorating Seiko's 100th anniversary. The SPB453 and SPB451 offer classic black and blue dials respectively, each accompanied by a stainless steel bracelet. The SPB455 introduces a charcoal gray colorway with gold accents, bundled with both a bracelet and a unique Seichu braided NATO-style strap crafted from recycled plastic bottles.

Enhanced Performance and Design

The previous generation of 62MAS reinterpretation watches boasted 200 meters of water resistance and 70-hour power reserves. However, Seiko aimed higher with the latest series, elevating the depth ratings to 300 meters and power reserves to a full three days. Achieving these improvements necessitated ingenious engineering solutions, including adjustments to caseback angles to maintain strength and reduce overall case profile.

Refined Dimensions and Construction

Measuring 40mm in diameter by 13mm thick with a lug-to-lug profile of 46.4mm, the new models are slightly smaller in every dimension compared to their predecessors. Crafted from stainless steel with a "super hard" coating for scratch resistance, these watches feature curved sapphire crystals, solid screw-down casebacks, and engraved aluminum bezel inserts matching the dial colors.
