The vintage watches that most directly inspired the new Hamilton Khaki Pilot Pioneer Chrono were created in the 1970s and worn by the British Royal Air Force. Hamilton designed the watches’ dials for maximum legibility in all lighting conditions, with bold Arabic numerals and hour indices coated with Super-LumiNova; on the black dial versions, the numerals and indices are white; on the ones with ivory-colored dials, they are in black. The 41-mm, stainless steel case of the Khaki Pilot Pioneer has an asymmetrical design with a protected crown and chronograph pushers. The sapphire crystal, like that of its 1970s predecessor, is domed, and is treated with nonreflective coating. Sandblasted elements on the case also aid in preventing glare in a cockpit (or any other environment). The case is water-resistant to 100 meters.
The movement in this new Hamilton pilots’ watch is the newly developed, proprietary Caliber H-31, based on the reliable ETA Valjoux 7753 (movement-maker ETA is Hamilton’s sister company in the Swatch Group). An automatic chronograph movement with a 60-hour power reserve, Caliber H-31 is visible through a sapphire window in the caseback. There are six versions of the Khaki Pilot Pioneer Auto Chrono overall, all pictured below: with either a black or ivory dial; on a three-row steel bracelet with brushed and polished finishes; on an aviator-style black leather strap; and — as the collection’s name implies — on a military-inspired, khaki-colored textile strap. The watch will retail for $1,845 in the U.S.
