This 200m Automatic Prospex Diver’s Special Edition watch encompasses the theme of a ‘tropical lagoon ‘and its colourful fish inhabitants.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.Powered by a hybrid solar-automatic calibre and paired with a navy blue reinforced silicone strap, the watch is designed for robust resilience when put to the test in extreme adventures – from recreational diving to simply wearing to the office.Bright emerald green and marine blue colours on the minute hand and bezel and the screw-down buttons in vivid green reflect the tropical ocean life inspiration behind the design.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.
