Quick TakeThis Khaki King is the gentleman adventurer's secret weapon. It’s got the rugged DNA of a field watch, born for action with its clear numerals and tough steel case, but the unique day-date display at the top gives it an air of authority, a crown for the king of the khaki collection. That beige dial isn’t just sand-colored; it’s the color of sun-baked earth on a long expedition. You get the sense this watch is equally at home mapping out a trail or navigating a Monday morning meeting. The real magic is the H-40 movement humming inside. An 80-hour power reserve means you can set it down on Friday after a long week and it’ll be ready to go, without missing a beat, when you pick it up again on Monday. It’s a reliable partner that doesn't demand constant attention, offering a blend of readiness and refinement that’s hard to find.

DescriptionThe Hamilton Khaki Field King Auto, under reference H64455523, is constructed with a stainless steel case measuring 40mm in diameter and 11.15mm in thickness. Its architecture includes a distinctive crown guard formation integrated into the case profile. A scratch-resistant sapphire crystal protects the beige dial, which is designed for high legibility with both a 12-hour and a supplementary 24-hour scale. The hands and hour markers are coated with Super-LumiNova for visibility in low-light conditions. A prominent feature is the full day-of-the-week aperture positioned at the 12 o'clock location, accompanied by a date window directly below. The case is rated for water resistance up to 5 bar, equivalent to 50 meters or 164 feet, and is completed with an open case back that provides a view of the internal mechanism.

Powering the timepiece is the Hamilton Caliber H-40 automatic movement. This self-winding mechanical movement is engineered for a substantial power reserve of 80 hours, a duration that significantly exceeds the typical industry standard and allows the watch to remain operational for over three days without being worn. The watch is affixed to the wrist via a 20mm wide cow leather strap, identified by reference H6007041041. This strap secures with a stainless steel pin buckle that has a width of 18mm, providing a slight taper from the lugs for enhanced comfort. The combination of these components results in a functional and durable timekeeping instrument intended for versatile use.
