There are just 4,000 of this limited edition timepiece available worldwide. This “Commando” style diver’s watch is a modern re-interpretation of the Seiko “Hybrid diver’s,” a world-first originally released in 1982 as a hybrid combination of analogue and digital watch technology. This model is also known as the “Arnie” after the actor who wore it in the film ‘Commando’ and its watch shape is nicknamed by Seiko fans as a ‘Tuna’ – because of its larger diameter and bold shape like a tuna tin.
This particular design is a celebration of the 40th anniversary of the world’s first hybrid diver’s watch with alarm chronograph. The original watch proved its reliability in extreme environments including the Japanese Antarctic Research Expedition in 1984 and the Joint Mount Everest Challenge made by the Japanese, Chinese and Nepalese team in 1988.
The new calibre H855 has been upgraded with improved visibility for diving, with a larger display at the 6 O’Clock position. It also features diving log, depth metre and temperature measuring functions.

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.
