Quick TakeThis isn't just a watch; it's a piece of tactical gear with a serious pedigree. The Khaki Navy Frogman feels like it was pulled directly from a naval diver's kit, and every single design choice reinforces that feeling. That massive, industrial-looking crown guard isn't just for show—it's a declaration of toughness, a functional centerpiece that screams this watch can handle pressure. Paired with 300 meters of water resistance, it’s a genuine tool for underwater exploration. Yet, Hamilton works some magic here. Despite its unapologetically rugged build, the finishing on the 42mm case and the precision of the black dial give it an unexpected versatility. The H-10 movement with its hefty 80-hour power reserve is the perfect modern touch, acknowledging that today's adventurer might rotate it with other pieces. It’s the ultimate weekend warrior, equally at home 100 feet below the surface or at a casual weekend barbecue, carrying an aura of capability wherever it goes.

DescriptionThe H77605135 model is constructed around a 42mm stainless steel case with a measured thickness of 12.5mm and a lug width of 20mm, ensuring a substantial presence on the wrist. Its architecture is purpose-built for aquatic environments, achieving a water resistance rating of 30 bar, which is equivalent to 300 meters or 934.2 feet (435 psi). This level of integrity is supported by the inclusion of a screw-down crown, further protected by a distinctive locking device that ensures security against water ingress during high-pressure activities. Protecting the black dial is a sapphire crystal, selected for its high scratch resistance and treated with an anti-reflective coating to maximize legibility in various lighting conditions. Visibility in low-light environments is guaranteed through the application of Super-LumiNova on the hands and indices.

Powering this timepiece is the Hamilton Caliber H-10, an automatic three-hand movement that includes a date complication. A key performance feature of this caliber is its extended power reserve of 80 hours, allowing the watch to remain operational for over three days without being worn or wound. The H-10 movement within the Khaki Navy collection features streamlined surfaces, reflecting its functional, performance-oriented application. The watch is completed by a stainless steel bracelet (reference H6057761051) that integrates seamlessly with the case and terminates in a folding clasp for a secure and reliable fitment.
