There are just 1,200 pieces available globally of this 1970 Diver’s modern reinterpretation timepiece, commemorating the 80th birthday of Japanese explorer Naomi Uemura, the first man in the world to climb the highest peaks of each five continents – wearing a Seiko diving watch.

The dial pattern is based on the mountainous surfaces that Naomi would have seen on his numerous treacherous climbs and subsequent dog sled alpine missions. The crown at 4 o’clock position for comfort and practicality is protected by the wide flowing case design around it, creating its signature look.

The design was named ‘Captain Willard’ by fans for Martin Sheen’s character who wore it in the ‘Apocalypse Now’ movie. Comes with bracelet and additional blue silicone strap featuring the ‘rail pattern’ from the archives of the original Seiko diver’s watch designs.

Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike. Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards.
