Hamilton Khaki Field Mechanical Power Reserve Mechanical | 40mm | H69509930

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 rugged khaki green NATO strap, the black dial proudly displays "power reserve 80 hours" and shows "F" for full and "E" for empty, to underscore this exceptional and utility-focused feature.
