Hamilton’s Khaki X-wind Marks 100 years of Time-keeping Precision

This is a milestone year for Hamilton Watch. The Swiss company marks 100 years since it became the official timekeeper of the U.S. airmail flights between Washington, Philadelphia and New York City.

To mark the occasion, Hamilton has created a special timepiece that represents the watchmaker’s long and storied history in aviation — the Hamilton 2018 limited-edition Khaki X-Wind Auto Chrono.

Based on the original Khaki X-Wind, the 2018 edition includes new aviation-specific features for pilots (such as a drift-angle calculator handy for judging crosswind component) and is equipped with a silicon hairspring, meaning it should deliver the same level of performance many years from now as it does when new.

This is a big watch, for pilots who like the look and feel of something substantial on their wrist. The diameter is 45 mm, and the thickness 14.85 mm. The case is made from stainless steel, and the dial is black with khaki accents. The watch comes with a leather strap and is water resistant to 100 meters. As a nod to its 100-year anniversary, Hamilton is limiting production of the 2018 version to 1,918 pieces.
