Get inspired to go higher with every look at the striking blue dial of the Khaki Aviation Converter Automatic. Pilots and urban adventurers can perform critical calculations and conversions mid-flight using the slide-rule bezel.
The Hamilton Khaki Aviation Converter Auto Chrono H76746540 will appeal mainly to fans of aviation style. The Khaki Aviation collection is designed with pilots in mind and built for a life full of adventure.
Inside the case, the Swiss mechanical Hamilton H-21-SI movement (based on ETA/Valjoux 7750) with automatic winding ticks reliably. It operates at a frequency of 28,800 vibrations per hour, has 25 jewels and, above all, an extended power reserve of 60 hours. The movement also has a "hacking" function (stopping the seconds hand when setting) and the option of manual winding via the crown. The movement can be observed through the transparent case back (sapphire crystal).
In addition to the time display, this model features a date and day-of-week function at the classic 3 o’clock position, as well as a practical stopwatch function (chronograph).
The stainless steel case is complemented by a well-made brown leather strap with a silver pin H buckle.
The model stands out for excellent legibility and clear layout, which is required for aviation watches. The blue dial is protected by a sapphire crystal. Sapphire crystal is a major advantage in watches, as it is almost impossible to scratch. The anti-reflective coating ensures excellent legibility even in bright sunlight.
The hands and indices are coated with a luminescent compound, ensuring better legibility even in poorer lighting conditions.
The 44 mm case diameter places the model among larger men’s watches. The watch has a water resistance of 100 m (10 ATM), so it can handle greater contact with water, such as swimming. Water resistance is supported by a screw-down crown.
The original leather strap for this model is designated H6007671081.

The Hamilton brand was founded in Lancaster, Pennsylvania, originally to produce only pocket watches. Thanks to the accuracy of the Hamilton watch, the problem of frequent accidents in the early days of railroad transportation in the United States was solved. It was the superior quality and accuracy of the first Hamilton pocket watches, as well as the ability to innovate and act quickly while maintaining high standards, that first caught the attention of the US military as early as 1914. As an official supplier to the US armed forces during World War I, Hamilton equipped hundreds of soldiers with reliable watches. This led to a shift in production from pocket watches to more comfortable wristwatches, a change that has stuck.
Groundbreaking, practical and precise: Hamilton uses a unique combination of Swiss precision and American spirit to create distinctive, versatile watches for style-conscious lovers. Hamilton has a long history and has achieved numerous milestones, all of which have contributed to making Hamilton the strong and internationally recognized watch brand it is today.
Helveti.eu is an authorized dealer and specialist of the Hamilton brand.
