Quick TakeThis isn't just a watch; it's your new co-pilot for any escapade you can dream up. The Khaki Field Expedition Auto feels like a modern classic that’s been dug out of a time capsule from a golden age of exploration. That bi-directional compass bezel isn't just for show—it's a tactile invitation to lose your way on purpose, knowing you have the means to find it again. Its 37mm size hits the sweet spot, large enough for clear legibility but compact enough that it never gets in the way of the actual doing. Inside, the H-10 movement is a beast, packing an 80-hour power reserve. You can set it down on Friday and pick it up Monday morning still ticking, ready for the week's new adventures. It’s got all the right specs for a proper field watch—sapphire crystal, a screw-down crown, and solid water resistance—but it wears with an understated confidence. It’s the kind of piece that’s equally at home charting a course in the wilderness or navigating the urban jungle.

DescriptionThe Hamilton Khaki Field Expedition, reference H70225931, is housed in a stainless steel case with a diameter of 37mm and a thickness of 11.45mm. Its architecture is designed for durability and functionality, featuring a screw-down crown that contributes to a water resistance rating of 10 bar, which is equivalent to 100 meters or 145 pounds per square inch. The black dial is protected by a scratch-resistant sapphire crystal that has been treated with an anti-reflective coating to ensure maximum legibility under various lighting conditions. For time-telling in low light, Super-LumiNova is applied to the hands and indices. An open case back allows for a view of the internal mechanism. The watch is secured to the wrist by a green textile strap, designated by reference H6006941021, which has a lug width of 20mm and fastens with an 18mm stainless steel pin buckle.

Powering this timepiece is the Hamilton Caliber H-10, an automatic, self-winding three-hand movement. A significant technical attribute of the H-10 is its extended power reserve of 80 hours, enabling the watch to run for more than three days without being wound. The movement's precision and reliability are further enhanced by the inclusion of a Nivachron balance spring, a modern alloy that offers superior resistance to magnetism, temperature fluctuations, and shocks. This ensures consistent timekeeping performance during various activities. The streamlined finishing of the movement components is visible through the exhibition case back, reflecting the watch's utilitarian purpose within the Khaki Field collection.
