Hamilton is keeping the spirit of early aviation alive with the Khaki Pilot Day Date Auto. Based on the design of cockpit instruments, and sporting white details against a dark dial, it's a throwback to the first days of flight. But with an oversized 46mm case and a see-through case back offering an uninterrupted view of the automatic movement, there's no doubting its up-to-date credentials. Featuring a black dial, crystal sapphire and stainless steel bracelet. Water resistant 200m.
