Introduction: A Military Icon, Off Duty

Few watches carry as much American history as the Hamilton Khaki Field. Its roots go back to the Second World War, when Hamilton stopped civilian production to supply the U.S. armed forces with tough, legible watches. After the war, soldiers came home, and the watches they had trusted became the everyday companions of a new generation. One of those postwar models was the Khaki King, a field watch people chose rather than were issued.

In 2026, Hamilton brought that spirit back with the Khaki Field King Day-Date. Hamilton describes it as a military icon "reimagined as a modern companion for modern adventure and exploration." The design keeps what made the Khaki Field famous, bold Arabic numerals, a rugged steel case and outstanding legibility, while removing the military 24-hour scale for a cleaner, more relaxed dial. The signature addition is the day and date at 12 o'clock, displayed in a contrasting tone.

The H64475560 at Lexor Miami is the green-dial version on a brown leather strap: the most classic, most "field" expression of the new collection. It is slim, comfortable and powered by a modern Swiss automatic with a full 80-hour power reserve.

In this guide we cover everything a U.S. buyer needs: Hamilton's American heritage, the history of the Khaki King, the H-40 movement, verified specifications, who this watch suits, how it compares with other Khaki Field models at Lexor Miami and why buying from an authorized dealer matters. If you are ready, order the Hamilton Khaki Field King Day-Date H64475560 here.

The Hamilton Story: American Spirit, Swiss Precision

Founded in Lancaster, Pennsylvania, in 1892

Hamilton was born in Lancaster, Pennsylvania, in 1892. It quickly earned a reputation for precision, becoming known as "the watch of railroad accuracy" at a time when precise timekeeping kept American trains safe and on schedule.

Pioneers of aviation and military timekeeping

Hamilton supplied watches for the first U.S. airmail service in 1918 and became a key supplier to the U.S. military. During World War II, the company devoted its production to the war effort, delivering hundreds of thousands of watches to American forces. Those rugged, highly legible designs are the direct ancestors of today's Khaki Field collection.

From Pennsylvania to Switzerland

Today Hamilton is part of the Swatch Group and produces its watches in Switzerland, combining its American design DNA with Swiss manufacturing and movement technology. That is why a Khaki Field King can honestly be described as American in spirit and Swiss in precision.

Hollywood's favorite watchmaker

Hamilton watches have appeared in hundreds of films. Its Khaki Field Murph, created for a science-fiction epic, became one of the most sought-after field watches of the last decade. That cinematic visibility has made Hamilton one of the most recognized watch brands in the United States.

The Khaki King legacy

The original Khaki King emerged in the years following World War II, as Hamilton shifted from military supply to civilian watches. Its name and character have returned in several forms over the decades, and the 2026 Khaki Field King Day-Date is the newest chapter: an off-duty field watch with a cleaner dial and a practical day-date complication.

Lexor Miami is an authorized Hamilton dealer, with one of South Florida's widest selections of Hamilton watches.

Benefits: Why the Khaki Field King Day-Date Works So Well

1. Weekend-proof power reserve

Many automatic watches stop after about 40 hours off the wrist. The H-40's 80-hour reserve means you can take the watch off on Friday evening and it will still be running on Monday morning. No resetting the day and date every time you switch watches.

2. Instant legibility

Big Arabic numerals, clear hands and Super-LumiNova make the time readable at a glance, day or night. The day and date at 12 o'clock are positioned exactly where your eye naturally goes first.

3. A practical everyday complication

Knowing the day as well as the date sounds simple, but it is one of the most used functions on any watch. For busy professionals, parents and travelers, the day-date display is genuinely useful every single day.

4. Slim and comfortable

At 11.8 mm thick, the Khaki Field King Day-Date slides easily under a shirt cuff and sits comfortably on the wrist all day, something many automatic day-date watches cannot claim.

5. Modern protection against magnetism

The Nivachron balance spring is far less sensitive to magnetic fields than traditional springs. With phones, laptops and magnetic closures all around us, that helps keep the watch accurate in real life.

6. A true Swiss automatic at an accessible price

At $795, you get a Swiss automatic movement, sapphire crystal, display case back, 100 m water resistance and a heritage name, a combination that remains one of the best values in Swiss watchmaking.

Is 40 mm the right size for you?

A 40 mm case with a lug-to-lug of about 50 mm is the most versatile size in men's watches. It suits wrists from roughly 6.25 to 7.75 inches comfortably, looks balanced on most men and on women who like a bolder watch, and its 11.8 mm thickness keeps it from feeling top-heavy.

The H-40 Movement: An 80-Hour Swiss Automatic

The signed stainless steel crown: wind and set the H-40 automatic movement.

What is the H-40?

The H-40 is Hamilton's day-date automatic caliber. It belongs to the family of modern Swatch Group movements developed from proven ETA architecture; WatchTime reports that it is based on the ETA 2834 platform. Hamilton has re-engineered it for a much longer power reserve.

80 hours of power

Traditional automatic movements of this type offered around 38 to 42 hours of reserve. The H-40 reaches up to 80 hours, roughly double, thanks to an optimized mainspring and a lower-frequency regulating system that consumes energy more slowly.

Nivachron balance spring

The Nivachron hairspring was developed within the Swatch Group as a titanium-based alloy that is far less affected by magnetic fields, temperature variations and shocks than traditional steel springs. In daily life, that means better stability around phones, laptops and speakers.

Reinforced construction

For the Khaki Field King Day-Date, Hamilton added a stainless-steel movement holder for extra resilience, an appropriate upgrade for a watch with military roots.

Visible through the case back

The transparent case back lets you watch the rotor turn as you move, a small pleasure that turns every glance at the back of the watch into a reminder that a mechanical engine is powering your day.

Hacking and hand-winding

Like most modern Swiss automatics, the H-40 can be wound by hand through the crown, and the seconds hand stops when you pull the crown to set the time, making it easy to synchronize precisely.

Design: A Closer Look

Side view: a slim 11.8 mm profile with a broad round bezel and brushed steel case.

A cleaner field dial

Classic Khaki Field watches carry an inner 24-hour scale, a reminder of military timekeeping. The Khaki Field King Day-Date removes it, opening up the dial and giving the watch a calmer, more off-duty character while keeping the bold Arabic numerals and minute track that make it a true field watch.

Sun-brushed khaki green

The H64475560's dial is a sun-brushed khaki green that shifts from deep olive in the shade to a lighter, almost bronze-green in direct light. It is a color with real military pedigree that also feels fresh and modern.

Day-date at 12 o'clock

The weekday appears in a segment-shaped window at 12 o'clock, spelled out in English, with the date directly below it. The windows are framed in a contrasting tone, and the 11 and 1 numerals are cropped to make room, a detail watch enthusiasts appreciate.

A broad, round bezel

The fixed round bezel gives the case a solid, confident look, while brushed and polished surfaces add refinement.

Brown leather with contrasting stitching

The brown cowhide strap with white contrast stitching is the classic field-watch pairing. It softens the case, ages beautifully and works with denim, chinos and tailoring alike.

Other versions

The Khaki Field King Day-Date collection also comes with black and blue dials and on a three-row steel bracelet. The green dial on brown leather is the most traditional and, for many collectors, the most authentic field-watch combination.

The Day-Date Display: A Closer Look

The day spelled out in full and the date below it, both at 12 o'clock.

How to set the day and date

Pull the crown to the date-setting position and turn it to advance the date. On many day-date automatics, the day is advanced by turning the crown in the opposite direction or by moving the hands through midnight. Always avoid changing the day or date between about 9 PM and 3 AM, when the calendar mechanism is engaged.

Why 12 o'clock matters

Most day-date watches place the windows at 3 o'clock. Putting them at 12 o'clock keeps the dial symmetrical and makes the information easier to read at a glance, especially when your wrist is turned slightly.

Field Watch Buying Guide: 5 Things to Check

"Field watch" has become a popular label, and many fashion brands now sell watches with Arabic numerals and khaki dials. If you want a real one, check these five points.

1. Legibility first

A true field watch is built to be read instantly: high-contrast numerals, clear hands and real luminous material. The Khaki Field King uses bold Arabic numerals and Super-LumiNova on both hands and markers.

2. A reliable movement

Look for a proven Swiss or Japanese movement with a solid power reserve. The H-40's 80 hours is one of the longest reserves in its price range.

3. Scratch-resistant crystal

Mineral glass scratches easily. Sapphire, as on the Khaki Field King, stays clear for years of daily wear.

4. Real water resistance

A field watch should survive rain, sweat and the occasional swim. The King is rated to 100 m, not the 30 m common on fashion watches.

5. Genuine heritage

Hamilton actually supplied the U.S. military, and the Khaki name comes from that history. That authenticity is part of what you are buying, and it is why Hamilton field watches hold their appeal long after trends move on. A watch with a real story is also simply more enjoyable to wear and to pass down.

Who Should Buy the Hamilton Khaki Field King Day-Date H64475560?

First-time Swiss automatic buyers

If you are ready for your first serious mechanical watch, this is one of the best places to start: Swiss-made, 80-hour reserve, sapphire, display back and a 2-year warranty at $795.

Lovers of military and vintage design

The Khaki Field heritage is genuine. If you appreciate watches with a real story, the Khaki King's postwar lineage gives this watch a meaning beyond its specs.

Busy professionals and parents

The day-date display at 12 o'clock and outstanding legibility make it a practical tool for anyone juggling a full calendar.

One-watch owners

With 100 m water resistance, a versatile green dial and an easy-to-change 20 mm strap, it can handle office days, weekends and vacations.

Wrists between about 6.25 and 7.75 inches

The 40 mm case and 11.8 mm thickness suit most men's wrists and many women who prefer a bolder watch.

Gift buyers

For graduations, promotions, anniversaries and Father's Day, a Hamilton field watch is a meaningful, lasting gift with American heritage.

Who might prefer another model

If you want a smaller, more vintage-sized watch, look at the 38 mm Khaki Field Murph. If you prefer the traditional 24-hour military dial, consider the Khaki Field Auto 42mm.

The Khaki Aviation Pilot Auto Day Date offers the same practical complication with pilot styling. If you prefer field-watch heritage and a green dial, the King is the better fit, and it costs $300 less.

For a dressier day-date, look at the Jazzmaster Day Date Auto. The Khaki Field King is the more casual, rugged and versatile option.

Versus Swiss rivals

Few Swiss automatic day-date watches under $1,000 match the King's combination of an 80-hour reserve, Nivachron spring, sapphire crystal, display back and 100 m water resistance. If you are cross-shopping, compare it with field and everyday watches from Tissot and Mido at Lexor Miami.
