The Khaki Aviation Pilot Auto models are perfect for true aviation enthusiasts, evoking the spirit of exploration and adventure. Now also available in a 36 mm version to match the current trend for smaller watches. The more compact designs meet precision standards for the cockpit, suited to life in the sky as well as on the ground in company. The Hamilton Khaki Aviation Pilot Auto H76215140 will particularly appeal to aviation style enthusiasts. The Khaki Aviation collection is designed with pilots in mind and built for a life of adventure. Inside the case, the Swiss mechanical movement H-10 (built on the ETA C07.611 built on the ETA 2824-2) ticks reliably with automatic winding. It operates at a frequency of 21,600 semi-frequencies per hour and features 25 jewels and, most importantly, an extended power reserve of 80 hours. The operation of the machine can be observed through a transparent dial. The movement also has a"hacking" function (stopping the second hand when ordered) and the possibility of manual winding with the crown. The flywheel of this movement is made of Nivachron alloy, which is more resistant to magnetic fields and temperature changes and results in better watch accuracy. The steel case of the watch is followed by a well-crafted steel bracelet with a folding clasp (the clasp has micro-adjustment). The model stands out for its excellent legibility and easy clarity, which is required for aviation watches. The dial in dark midnight blue is protected by a sapphire crystal. The sapphire crystal is a great advantage in watches as it is almost impossible to scratch. The anti-reflective layer guarantees great legibility even in the harsh sunlight. The hands and indices are coated with a luminescent layer, which guarantees longer luminosity and better legibility even in low light conditions.
