The Hamilton Khaki Field King Day-Date Automatic is one of the brand's most popular models.
This is not surprising, as its expressive design and extensive functionality provide excellent value for money. Today, we will look at the new version of this field chronometer, where the military style is less pronounced. Let's dive into the details!
Versions and Prices of Hamilton Khaki Field King Day-Date Automatic
The new version of the Hamilton Khaki Field King Day-Date Automatic is available with dials in three colors: black, blue, and green. The model is priced at €825 / £715 / US$845 on the standard steel bracelet and €745 / £640 / US$795 on a leather strap. Unlike some brands, Hamilton does not limit the choice of dial and strap combinations, so you can select any configuration you like. Note this point, as it is important for selection.
Military Heritage of Hamilton
Although the new version of the Hamilton Khaki Field King Day-Date Automatic is less military in style, it is important to understand where it comes from. Founded in 1874 in Lancaster, Pennsylvania, initially named Adams & Perry Clocks, Hamilton has deep military roots. The American brand supplied watches to American troops during both World Wars. During World War II, civilian watch production was completely halted to focus on military orders.

Original Model Khaki Field King Automatic
After World War II, Hamilton resumed civilian watch production. Despite this, the brand continued to produce military models, supplying watches to the US armed forces during the Vietnam War. However, the priority shifted towards civilian models. The modern release essentially marks this transition, demilitarizing the classic Khaki Field King Day-Date Automatic model.

What’s New in the Hamilton Khaki Field King Day-Date Automatic?
The main difference in the new version is the removal of the 24-hour scale from the dial. While in Europe this scale is not so closely associated with military timekeeping, for Hamilton, it is an important symbol. Press releases emphasize that this change aims to create more versatile sports watches for everyday use.

The technical specifications remain the same. The stainless steel case is 40 mm in diameter with a thickness of less than 12 mm. Inside is the automatic caliber H-40 - a version of Swatch Group's Powermatic 80 with an 80-hour power reserve and a frequency of 21,600 vibrations per hour (3 Hz). Sapphire glass with anti-reflective coating and a transparent case back are retained. In the new model, water resistance is increased from 50 to 100 meters, making the case 0.7 mm thicker.

The dial has undergone significant changes: the clutter with several rings of different finishes has disappeared, and the 24-hour scale has been removed, making the design cleaner, simpler, and more universal.

First Impressions of the Hamilton Khaki Field King Day-Date Automatic
Reducing the military stylistic emphasis in the watch is a positive step. Personally, I never associated this model with a military theme as strongly as with other Hamilton field watches. Moreover, the simplification of the dial has led to the emergence of a typical Type A, which also has military origins. Nonetheless, watches should be evaluated for their real qualities rather than their history.
The new version looks less aggressive and more friendly. It has indeed become more versatile and better suited for everyday wear. The readability of the dial has improved. The only downside is that the day window now more noticeably "cuts off" the numbers 11 and 1, which was not so noticeable before due to the more complex design.

Overall, the model promises to be successful for Hamilton. The feature set and appearance make it attractive to a wide audience. If you prefer a more minimalist dial design, this model can be confidently recommended.
