Quick TakeThis isn't just a watch; it's a trusty piece of gear begging for an adventure. The Khaki Field Expedition Auto feels like it was born in a dusty map room, designed for someone who prefers a trail to a sidewalk. Its compact 37mm case is a throwback to classic field watches, fitting perfectly without ever getting in the way. You can feel the robust build quality, from the solid grip on the screw-down crown to the sturdy stainless steel body. The black dial is all business—clear, legible, and ready for a quick glance, day or night, thanks to a generous application of Super-LumiNova. But the real magic is the H-10 movement humming inside. Knowing you have an 80-hour power reserve means you can set it down Friday and pick it up Monday morning without missing a beat, ready for whatever the week throws at you. It’s a no-nonsense, reliable companion that combines vintage military spirit with modern watchmaking muscle.

DescriptionEngineered for durability and precision, the Hamilton Khaki Field Expedition Auto, reference H70225830, is housed within a stainless steel case measuring 37mm in diameter with a thickness of 11.45mm. The case architecture incorporates a screw-down crown, a critical feature ensuring water resistance integrity up to 10 bar, equivalent to 100 meters or 145 psi. A scratch-resistant sapphire crystal, treated with an anti-reflection coating, protects the black dial, enhancing legibility under various lighting conditions. For observation of the internal mechanics, the watch is equipped with an open case back, offering a view of the movement. The lug width is a standard 20mm, providing for a balanced and secure attachment to the wrist.

The timepiece is powered by the Caliber H-10 automatic movement, a self-winding three-hand mechanism. This caliber is notable for its extended power reserve of 80 hours, a significant increase over standard automatic movements. The inclusion of a Nivachron balance spring contributes to its reliability by offering superior resistance to magnetic fields, temperature variations, and shocks. The dial features indices and hands treated with Super-LumiNova for clear visibility in low-light environments. The watch is fitted with a calf leather strap, identified by reference H6000001571, which tapers from the 20mm lug width to an 18mm stainless steel pin buckle, ensuring a secure and comfortable fit.
