The Khaki Aviation Pilot Day-Date 42 expands on Hamilton’s legacy in aviation, offering a sophisticated balance of tradition and modernity. This series includes three 42 mm references, each featuring the H-30 automatic movement with a substantial 80-hour power reserve and a Nivachron™ balance spring. The day-date window and nickeled hands enhance functionality, while the aesthetics pay homage to the heritage of aviation and outdoor adventure. Choices include a stainless-steel bracelet with a blue dial, light leather with a silver dial, and dark leather with a green dial. These designs are both an ode to the pioneering spirit of early flight and a nod to the rugged, adventurous spirit of the Khaki line, suitable for wear in any setting.
