Hamilton Khaki Pilot Pioneer Mechanical Chronograph

With a distinct vintage military aviation design, Hamilton’s Khaki Pilot Pioneer Mechanical Chronograph brings back the form and function of the chronographs issued to British Royal Air Force pilots in the 1970s. Rugged and reliable, the 40mm watch is powered by an exclusive hand-wound H-51-Si movement.

The new Khaki Pilot Pioneer Mechanical Chronograph celebrates classic military aviation design with authentic style and engineering.

True to its historic roots, it recalls recognizable details of the chronographs we produced for British Royal Air Force (RAF) pilots in the 1970s, making it a must-have for military history enthusiasts, aviation experts and watch collectors.

Two horizontally aligned subdials – measuring minutes and running seconds – stand out against a black-grained dial .

Hands coated in a white lacquer consistent with the original RAF models furthers the Pilot Pioneer’s heritage appeal.

Also used on the dial markings, its beige-tone is reminiscent of the patina found today in vintage radium-based lume and ensures clarity in low light conditions.

The commitment to authenticity continues inside with our high-performance H-51-Si mechanical movement.
