Sporty and functional, the Khaki Field Power Reserve 40mm stands out with a blue dial and a durable NATO strap, which together create a lightweight combination made for adventure. The power reserve indicator and perfectly sharp numerals underline the emphasis Hamilton places on maximum legibility and practicality. This watch is ideal for everyday wear as well as outdoor activities – it perfectly combines field-tested reliability with a relaxed modern style.
Thanks to the new hand-wound H-23 movement, developed by ETA exclusively for Hamilton, it allows (for the first time) visualisation of the 80-hour power reserve directly on the dial. The blue dial, fitted with a robust blue NATO strap, proudly displays “power reserve 80 hours” and “F” for full and “E” for empty, to underline this exceptional and utility-focused feature.
The men’s watch Hamilton Khaki Field Mechanical Power Reserve 40 mm H69509940 belongs to the Khaki Field line and, thanks to its design, is suitable for everyday wear.
The case of the Hamilton H69509940 is made of stainless steel and the watch stays on the wrist thanks to a high-quality textile strap with a pin buckle.
Inside the case, the Swiss mechanical H-23 movement with manual winding and hacking function (stopping the seconds hand when setting the time) works reliably. The movement has an extended power reserve of 80 hours.
The balance spring of this movement is made from the Nivachron alloy, which is more resistant to magnetic fields and temperature changes and contributes to better accuracy of the watch.
The elegant yet clear blue dial is protected by a sapphire crystal, which is highly resistant to scratches. The anti-reflective coating ensures excellent legibility even in bright sunlight.
The watch has a water resistance of 100 m (10 ATM), so it can handle greater contact with water, such as swimming.
The 40 mm case diameter makes the watch wearable for most men’s wrists.
The original strap for this model is designated H6006821051.

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.
