The Hamilton Khaki Aviation X-Wind Auto Chrono 44mm Blue Dial Brown Leather H77506540 is part of Hamilton's Khaki Aviation X-Wind Auto Chrono collection, housed in a 44mm stainless steel case on a calfskin leather strap. A blue dial paired with Hamilton's Swiss-made automatic chronograph Caliber H-21 with 60 hours power reserve makes this an authentic, brand-new piece in our INCMAXX collection. The Khaki Aviation X-Wind features the world's first drift angle calculator on a wristwatch — a complication that allows pilots to compute crosswind compensation in real time, cementing Hamilton's reputation as the premier American aviation watchmaker.
