Quick TakeThis isn't just a watch; it's a piece of sub-aquatic survival hardware that happens to tell time. You can feel the purpose-built design in the surprisingly light 46mm titanium case—it’s a gentle giant on the wrist, not an anchor. The massive crown guard isn't for show; it's a locking metal bridge, a final "all clear" before you descend into the crushing pressure of the deep. That vibrant red bezel is your lifeline, a stark, unmissable countdown against the abyss. With a thousand meters of water resistance, this Frogman scoffs at recreational diving limits and dares you to find its breaking point. And the H-10 movement? Its 80-hour power reserve means it’s ready to go even after a few days of well-earned shore leave. It’s a tool that exudes confidence, a silent partner for those who venture where the sun doesn't shine.

DescriptionThe Hamilton Khaki Navy Frogman, reference H77805335, is constructed around a substantial 46mm case fabricated from lightweight and durable titanium. With a total thickness of 15.95mm, the housing is engineered for extreme environments, providing water resistance up to 100 bar, which is equivalent to 1000 meters or 3280.8 feet. The integrity of the case is further ensured by a screw-down crown, which is protected by a distinctive locking mechanism for maximum security against water ingress during deep-dive operations. Protecting the black dial is a sapphire crystal, selected for its superior scratch resistance and treated with an anti-reflective coating to ensure optimal legibility under all lighting conditions. The design integrates a 22mm lug width, accommodating a robust strap engineered for performance.

At the heart of this timepiece is the Caliber H-10 automatic movement, a sophisticated three-hand mechanical engine that includes a date function. This movement is notable for its extended power reserve of 80 hours, allowing the watch to remain operational for over three days without being worn or wound. The black dial features prominent markers and hands designed for clarity, with a contrasting red-tipped seconds hand for precise time reading. The watch is fitted with a black rubber strap (reference H6007781001) that tapers to a 20mm pin buckle, ensuring a secure and comfortable fit on the wrist or over a wetsuit. This combination of advanced materials and mechanical precision defines its role as a professional-grade diving instrument.
