Hamilton Khaki Navy Frogman Automatic Black Dial Rubber Strap Men's Watch H77855330
The Hamilton Khaki Navy Frogman Auto H77855330 is Hamilton's most technically advanced maritime timepiece, built for superior performance in the most demanding underwater conditions. It features a robust stainless steel case with a black PVD coating and a unique crown protector, combining a rugged, tactical aesthetic with professional-grade functionality. The black rubber strap, with its wave-like texture, completes the diver's look.
Automatic Movement with Enhanced Durability
At the heart of the Frogman is the H-10 automatic movement, which boasts an impressive 80-hour power reserve. This self-winding calibre provides a three-hand function and a date display, offering practical information for everyday use and adventure. The movement is also equipped with a Nivachron™ balance spring, a state-of-the-art material that provides superior resistance to magnetic fields and shocks, ensuring consistent and reliable timekeeping.
A Dial for Maximum Legibility
The black dial is designed for maximum clarity, even in the murkiest depths. The hands and markers are generously coated with Super-LumiNova, guaranteeing exceptional visibility in low-light conditions. The unidirectional rotating bezel allows for precise measurement of dive time, a critical feature for any professional diver.
Built for the Deep – Form Meets Function
With a substantial 46mm case diameter and a thickness of 13.58mm, the Khaki Navy Frogman has a commanding presence on the wrist. The screw-down crown and solid case back contribute to its formidable 300m (30 bar) water resistance, making it suitable for serious diving. The durable rubber strap and lug width of 22mm provide a secure and comfortable fit.
A Heritage of Excellence
As a tribute to the legacy of the original "Frogman" watch, created for U.S. Navy divers during World War II, the Khaki Navy Frogman Auto is a watch for those who value heritage and professional-grade performance. It is a timepiece that is as comfortable in the urban jungle as it is in the ocean's depths, offering reliability and style for any adventure.
