Khaki Aviation X-Wind Auto Chrono

Automatic | 45mm | H77906940

Innovative, adventurous and accurate. It's what pilots need in a timepiece and Hamilton always delivers. The Khaki X-Wind features the first ever drift angle calculator to appear in a watch and helps pilots accurately calculate how crosswinds will affect their journey. With a technical look and automatic movement that also suits urban aviators down to the ground it's the perfect everyday co-pilot. This new model has a 45mm case and adds a stealth element to its look with black PVD coating.

H-21-Si

The H-21-Si is an automatic chronograph movement featuring a state-of-the-art balance spring made from the anti-magnetic material silicon for enhanced resistance to extreme atmospheric conditions. With an extended 60-hour power reserve, this powerful caliber reliably keeps and measures time via two or three sub dials at 6, 9 and/or 12 o’clock, and start/stop and reset pushers on the side.
