Seiko Prospex 1968 Heritage Diver's GMT Watch

Seiko Diver's Watch 60th Anniversary Limited Edition – limited to 6000 pieces worldwide

A Tribute to 60 Years of Seiko Dive Watches

With the Seiko Prospex 1968 Heritage Diver's GMT Watch, Seiko celebrates the 60th anniversary of its dive watch line – a milestone in the history of professional timepieces. Inspired by the iconic 1968 high-frequency model, this limited edition combines historic design elements with cutting-edge technology. The dial with its powerful wave pattern evokes the unpredictability of the ocean – a symbol of adventure, freedom, and the spirit of exploration.

Limited Edition with Newly Developed GMT Caliber

The watch is equipped with the new automatic movement 6R54, which offers a 72-hour power reserve as well as a GMT function. With a separate 24-hour hand, two time zones can be reliably read – ideal for globetrotters and deep-sea divers. The engraving on the case back marks the model as a LIMITED EDITION (1 of 6000 pieces).

Built for True Professionals

The water resistance up to 300 meters, the unidirectional rotating bezel, the anti-reflective sapphire crystal, and the robust screw-down crown make this timepiece the ideal companion under extreme conditions. The new strap with quick-adjust clasp allows extension by up to 15 mm – without tools, with just one push of a button.
