WHAT WE LOVE:

Inspired by the captivating marine blues of Okinawa, one of the world’s most renowned diving destinations, the 40mm Seiko Prospex 1965 Heritage Diver’s Watch celebrates both heritage and oceanic beauty. The Okinawa Marine Blue dial mirrors the vivid hues created as sunlight dances across coral sands beneath the waves. It unites vintage design, modern craftsmanship, and Seiko’s enduring Save the Ocean commitment to protecting marine environments for future generations.

The Seiko Prospex SPB545J is more than just a watch; it is a celebration of Seiko’s proud diving legacy. This 1965 Heritage Diver's Watch, crafted as a Limited Edition of just 4000 pieces, reflects both innovation and reverence for the ocean.

Comfort is equally prioritised with a newly engineered clasp that allows six incremental adjustments of approximately 2.5mm each, offering up to 15mm in total flexibility. This ensures an ideal fit whether you're diving deep or navigating daily life.

With a stainless steel case measuring 40mm in diameter and 13mm in thickness, the SPB545J strikes a perfect balance between vintage inspiration and modern wearability. A curved sapphire crystal with anti-reflective coating on the inner surface ensures legibility in all conditions, while Seiko’s LumiBrite treatment on the hands, indices, and bezel provides brilliant visibility in the dark. Its unidirectional rotating bezel, screw-down crown, and robust screw case back enhance its reliability under pressure, making this timepiece a true diver’s companion. 

WHAT'S INSIDE:

Powering the SPB545J is Seiko’s in-house Caliber 6R55, an automatic movement with manual winding capability. It offers an impressive power reserve of approximately 72 hours, and operates with a precision range of +25 to -15 seconds per day. With 24 jewels and a stop second hand function for precise time-setting, this movement is engineered for both performance and longevity.

Built to endure the depths with a water resistance rating of 300 meters, and boasting magnetic resistance of 4,800 A/m, the Seiko Prospex SPB545J is as reliable as it is refined, a watch designed for those who honour tradition, embrace innovation, and live with purpose.
