Defining Hamilton’s Evolution

To understand what defines the Hamilton Khaki Field collection, we must travel back to the beginning. Founded in 1892 in Lancaster, Pennsylvania, Hamilton was one of the key players during the era where the United States led the worldwide timepiece production.

Fast forward to 1912, Hamilton produced sturdy and reliable pocket watches for railroad conductors. These devices help conductors to check the time and keep the trains on schedule. At this time, a poor timekeeping device could trigger a chain of disaster. Hence, Hamilton's accurate timekeeping mechanism was officially acknowledged as the “Railroad Timekeeper of America”.

During the First World War, Hamilton shifted its focus to wearable compact timekeeping devices for American G.I.s. Even though pocket watches were still popular for gentlemen, they were not feasible to wear on battlefields. It wasn’t until 1942 that Hamilton ceased every civilian product for the effort in mass producing precise watches for the war effort.

However, the American watch company was acquired by Switzerland's Swatch Group in 1974 though the brand had already relocated the manufacturing to Switzerland since 1969. This massive shift led to the revival of civilian watches under the Khaki category. Hamilton shifted to producing military-designed watches for civilian use in the post-Vietnam War era.

Khaki Field was made in the image of the Khaki Navy Aviation. It was a pilot watch collection for military divers in the 1950s. To this day, Khaki Field has become the core of the Khaki collection. It utilizes various materials to construct the case, bracelet, and strap. The movements also vary, including manual winding mechanical, automatic, and quartz.

Hamilton Khaki Field Automatic at a Glance

One look at the Hamilton Khaki Field Automatic can tell a lot about its history and the significant influence of the American military in its design. However, most of the Hamilton Khaki Field watches in the market today bear the characteristics of the Hamilton production during the Vietnam War era. Nevertheless, the collection still has the classic military field watch signature, such as decent lumination and dependable water resistance.

The Hamilton Khaki Field Automatic offers a sensible timekeeping option for those who are not used to regularly winding watches. For practical purposes, the Khaki Field Automatic also features a date indication, which may help in daily schedule arrangement.

As for the sizes, the Khaki Field Automatic comes in three options, which are 38 mm, 40 mm, and 42 mm. The 38mm watches are slightly thicker than manual-winding watches in the collection by 10 mm. These watches are powered by the self-winding automatic movement, H-30, a modified version of the ETA C07.621 “Powermatic” caliber. For the record, the C07.621 caliber has an 80-hour power reserve. Additionally, the H-30 includes a customized rotor and an enhanced escapement regulator.

Every available model only shows the date on the 3 o’clock window, except for some of the 42mm models. Within the 42mm watch cases, the Day-Date versions are all outfitted to the steel or PVD-coated steel.

However, a selection of Khaki Field Automatic watches only display the time on three hands without the accompaniment of the day-date feature. Most recent example is the Khaki Field Titanium Auto subcollection.

One of the iconic no-date Hamilton Khaki Field Automatic watches is the Hamilton Khaki Field Murph Automatic. The design was inspired by the Hamilton watch worn by the character Murph in Christopher Nolan’s Interstellar.

For all intents and purposes, the Khaki Field Murph Automatic was the exact replica of the watch in the movie. The difference lies in the second hand, where the subtle Morse code of “Eureka” is printed in lacquer. In the movie, audiences can see Murph use the watch to save the world by sending coded signals.

Overall, the Hamilton Khaki Field Automatic watches exude timeless aesthetic with reliable modern features. Unlike the manual-winding Field watch, the auto version offers convenience in the forms of automatic movement and date display.
