The Khaki Field Mechanical Power Reserve 40mm honors the heritage design and essential functionality of the Khaki family, while introducing modern features and the latest in watchmaking technology and innovation. With a new manual-winding H-23 movement, developed by ETA exclusively for Hamilton, it allows (for the first time) for the 80-hour power reserve to be visualized directly on the dial. Fitted with a stainless steel metal bracelet, the white dial proudly displays "power reserve 80 hours" and shows "F" for full and "E" for empty, to underscore this exceptional and utility-focused feature.

I wanted a field watch with a white face vice the usual black; the Hamilton did not disappoint. The look is utilitarian and classy—the white face works well with the included brushed steel bracelet and a faded green one-pass strap from my collection. I must say that the “fuel gage” for the power reserve is a stroke of genius and a remarkably cool and useful addition to the standard Hamilton lineup. If you worked in a day/date complication on the “3” side, you’d create about the perfect field watch. The 80-hour reserve is a great feature that allows you to go watch-free on a lazy weekend without having to wind and reset the time on Monday.
