Overview
The Hamilton Khaki Aviation Pilot Day Date Auto (ref. H64615135) is a 42 mm stainless steel pilot's watch powered by the in-house-developed Cal. H-40 automatic movement. Its black dial carries luminous Arabic numerals and a combined day-date display, keeping the instrument-panel aesthetic that has defined the Khaki Aviation line for decades. The reference sits squarely in Hamilton's tradition of producing legible, field-ready watches with broad everyday appeal.
History
Hamilton's Khaki Aviation line traces its roots to the brand's long history of supplying purpose-built timepieces to military and civil aviation communities. The H64615135 was introduced around 2016 and has remained in continuous production, reflecting sustained collector and enthusiast interest in honest pilot-tool watches at an accessible tier of the market. The Cal. H-40 movement, developed within the Swatch Group's movement-making infrastructure, brought a fully automatic option to a segment of the Khaki Aviation catalogue that had previously relied on quartz or hand-wound calibres.
