Seiko Prospex “Mystic Lagoon” Captain Willard – exclusively available through our Knightsbridge boutique.

Inspired by the deep blue colour of a diver’s fantasy of a mysterious Japanese lagoon, this timepiece is only available from selected Seiko boutiques worldwide – exclusively from our Seiko boutique in Knightsbridge, London.

The shape of this 1970 Diver’s modern reinterpretation timepiece was named ‘Captain Willard’ by fans for Martin Sheen’s character who wore it in the ‘Apocalypse Now’ movie.

The original 1970 Diver’s timepiece was worn by Japanese explorer Naomi Uemura, the first man in the world to climb the highest peaks of each five continents – wearing a Seiko diving watch whilst he did it.

This version comes with calibre 6R35 and its long-lasting 70 hour power reserve.
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.

Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ These timepieces are designed to be practical, reliable and durable within extreme or everyday environments, for experts, sports lovers and adventure seekers alike.
