Quick TakeThis isn't just a watch; it's a piece of tactical underwater equipment that happens to look fantastic on dry land. The Khaki Navy Frogman has a personality forged in the deep. That formidable crown-locking device feels like something straight out of a submarine hatch, a satisfyingly tactile assurance that the watch's internals are sealed tight against the crushing pressure of the abyss. The vibrant blue of the dial and bezel isn't just a color choice; it's a reflection of the watch's natural habitat. On the wrist, the 42mm case has a confident heft that speaks to its durable construction, yet it avoids feeling oversized. Powering this aquatic explorer is the workhorse H-10 movement. Knowing you have an 80-hour power reserve is a genuine convenience, meaning this Frogman is ready for a spontaneous dive or a weekend adventure even if it’s been sitting on the nightstand. It’s a tool, a statement, and a reliable companion all in one rugged package.

DescriptionThe Hamilton Khaki Navy Frogman, reference H77705145, is engineered with a robust stainless steel case measuring 42mm in diameter and 12.5mm in thickness. Its architecture is designed for aquatic environments, featuring a screw-down crown protected by a locking bridge mechanism to guarantee water resistance up to 30 bar, which is equivalent to 300 meters or 435 psi. The dial is shielded by a sapphire crystal treated with an anti-reflective coating to ensure maximum legibility under various lighting conditions. A unidirectional rotating bezel with a blue insert allows for the tracking of elapsed time, a critical function for diving applications. The lug width is a standard 20mm, accommodating the specified stainless steel bracelet.

Internally, the timepiece is powered by the Caliber H-10 automatic movement. This three-hand caliber is notable for its substantial 80-hour power reserve, reducing the need for frequent winding. The movement's reliability is complemented by the highly functional dial layout. The blue dial surface presents large, geometrically distinct hour markers and hands, all of which are coated with Super-LumiNova for persistent luminosity in dark conditions. For added utility, a date function is integrated into the dial, displayed through a small aperture. The watch is completed with a stainless steel strap, reference H6057761051, that secures to the wrist with a folding clasp for dependable wear.
