Quick TakeForget the beaten path; this is a watch for carving your own. The Khaki Field Expedition Auto isn't just a time-teller, it's a trusty piece of gear that feels born for adventure. That solid 41mm steel case and screw-down crown aren't for show—they're a promise of durability, ready for a sudden downpour or an unexpected river crossing with its 100m water resistance. The compass bezel is a brilliantly simple, battery-free tool that beckons you to look up from your phone and actually navigate. Inside, the H-10 movement is a workhorse, quietly ticking away for over three days straight without a wind. It's the kind of reliability you need when you're truly off-grid. Matched with that sturdy steel bracelet, it has a go-anywhere, do-anything attitude that’s just as comfortable mapping out a trail as it is grabbing a celebratory beer afterward. It’s a tool, a companion, and a statement that your adventures are just getting started.

DescriptionThe Hamilton Khaki Field Expedition, with reference number H70315130, is constructed from stainless steel, forming a case that measures 41mm in diameter and 11.5mm in thickness. A key functional element is the screw-down crown, which aids in securing the case against water ingress up to a pressure of 10 bar, equivalent to a depth of 100 meters or 145 psi. The watch face is protected by a sapphire crystal, which has been treated with an anti-reflection coating to enhance dial legibility. For low-light conditions, Super-LumiNova is applied to critical elements on the black dial. The design includes an open case back, allowing for a view of the internal movement. A lug width of 20mm is specified for strap and bracelet integration.

Powering the timepiece is the Caliber H-10, a self-winding mechanical movement. This three-hand caliber is notable for its extended power reserve of 80 hours. The incorporation of a Nivachron balance spring enhances the movement's performance by providing increased resistance to magnetism, temperature fluctuations, and physical shocks. The watch is fitted with a stainless steel bracelet, identified by strap reference H6050000071, which features a folding clasp. The buckle width for this clasp is specified at 18mm. The movement's surfaces are finished in a streamlined manner, aligning with the watch's utilitarian purpose.
