This diver's watch is a modern reinterpretation of Seiko's groundbreaking 1982 "Hybrid diver's" model, known as the 'Arnie' for its association with the actor in the film 'Commando' and nicknamed 'Tuna' by Seiko fans due to its bold, tuna tin-like shape. It celebrates the 40th anniversary of the world's first hybrid diver's watch with an alarm chronograph, which proved its reliability in extreme conditions like the Japanese Antarctic Research Expedition in 1984 and the Joint Mount Everest Challenge in 1988. This multifunctional timepiece is built for both practicality and performance, featuring Lumibrite hands and indexes for enhanced visibility in low-light conditions. A screw-down crown ensures added water resistance and durability, while the unidirectional rotating bezel allows for precise time tracking. Designed with convenience in mind, it also includes an alarm function and LED illumination, making it a reliable companion for everyday wear and outdoor adventures alike. Powered
