Quick TakeThis isn't just a watch; it's a piece of gear that feels born for the mission, whatever you define that to be. The Hamilton Khaki Field Auto Chrono in full blackout attire is pure tactical precision with a pulse. Its 42mm PVD-coated case is like stealth armor for your wrist, ready for anything from a weekend expedition to navigating the concrete jungle. Forget battery anxiety; the H-21 automatic movement inside is a mechanical powerhouse, stockpiling a solid 60 hours of power. You can literally set it down on Friday and pick it up Monday morning still ticking accurately. The chronograph is there for when every second counts, and the screw-down crown and 100-meter water resistance mean it won't flinch at a sudden downpour or an impromptu swim. Peeking through the open case back reveals the decorated movement, a reminder that even the most rugged tools can possess a sophisticated, beating heart. It's less of a time-teller and more of a trusted companion.

DescriptionThe Hamilton Khaki Field Auto Chrono, designated by reference number H71626735, is a timing instrument constructed to specific functional standards. The case is fabricated from stainless steel and given a black PVD coating, yielding a diameter of 42mm and a total thickness of 14.5mm. Protecting the black dial is a sapphire crystal, which has been treated with an anti-reflection coating to mitigate glare and enhance readability. Legibility in low-light conditions is facilitated by the application of Super Luminova on indices and hands. The architecture ensures water resistance to a depth of 100 meters (10 bar or 145 psi), a rating fortified by the inclusion of a screw-down crown which provides a more secure seal against moisture ingress.

Powering the timepiece is the Caliber H-21, an automatic chronograph movement. This mechanical system operates autonomously from a battery, winding itself via the motion of the wearer, and offers an extended power reserve of 60 hours. The movement's functionality and the signature H-pattern design on its oscillating bridge are observable through the transparent open case back. The watch interfaces with the wrist using a strap (reference H6006841361) that measures 20mm at the lugs and is fastened with a 20mm pin buckle, ensuring a secure and correctly sized fit.
