In the 1970s, Hamilton supplied British Royal Air Force pilots with hand-wound chronographs.The new Hamilton Khaki Pilot Pioneer Mechanical Chronograph is a tribute to the watches used by Lightning, Harrier Jump Jet, and Vulcan pilots.Inside the 40mm steel case beats the hand-wound H-51-Si movement, and looking at the dial, it seems little has changed.But let's find out how the new version holds up in a hands-on review.Back in 2017, Mike Stockton wrote about the original chronograph that Hamilton made for the RAF back in the 1970s.In his conclusion, he stated, The Hamilton Military Chronograph is a really purposeful looking watch with great history.The fact that these watches were really used on the job where the British Commonwealth was participating in various conflicts adds a dose of realism to these tool watches too.Me, I like the fact that it's extremely wearable and simply attractive.And if you look at the watch, it's easy to see why he enjoyed the chronograph that was outfitted with a Valjoux 7733 movement.The dial looks purposeful, and the case shape is interesting.The watch makes me think of my favorite RAF plane from that era, the English Electric Lightning.It was a Mach 2 interceptor with two engines on top of each other and a most-elegant wing design.
