Created for the US naval â€ofrogmenâ€? teams and featured in the 1951 smash-hit movie The Frogmen, this new diver watch is clearly built to meet the high demands of its underwater vocation. This 42mm stainless steel case version features a blue aluminum unidirectional rotating bezel and is water-resistant up to 30 bar / 300 meters with screw down crown protection. Powering the watch is Hamilton\'s H-10 Swiss made automatic mechanical movement, with date function and incredible 80 hour power reserve, displaying the time with a striking blue dial with highly contrasting batons and hands, all coated with luminous material for maximum visibility in any condition. Protecting the dial from scratches is a sapphire crystal, and the watch is fitted with a solid stainless steel bracelet with fold over deployment clasp.
