The Hamilton Khaki Aviation X-Wind Auto Chrono (H77616533) is a pilot’s chronograph built around a crosswind drift angle calculator on the bezel, which Hamilton says helps pilots work out how crosswinds will affect a flight. Hamilton’s official page lists a 44 mm stainless steel case, 15.55 mm thick, with 22 mm lug width, a sapphire crystal, an open case back, a screw-down crown, a black dial and 100 m (10 bar) water resistance. The H-21 automatic caliber shows chronograph, date and day, with a 60-hour power reserve. It is on a cow leather strap and Hamilton lists it at $2,095 in the US.

We did not find an independent review of this specific reference; the available coverage is retailer and brand listings. Hamilton’s own page shows a 5 out of 5 rating from 8 customer reviews, praising accuracy and comfort, although that is a small sample on the brand’s site.

The X-Wind Auto Chrono is part of Hamilton’s current collection and is listed on the official store.
