Stepping up in Hamilton's range
The Khaki Field has always been rooted in military utility, and this reference marks a specific step forward within that line: the first in the collection to bring the power reserve indicator onto the dial itself. The H-23 that drives it was developed with ETA specifically for Hamilton, and its 80-hour reserve is displayed through a dedicated sub-dial at 9 o'clock — marked F and E in red, legible at a glance without needing to count wound turns or remember when you last set it. At 40mm with a sandblasted steel case sitting just under 12mm thick, the proportions are balanced without being cautious. The white dial reads clearly in most light, and the Old Radium Super-LumiNova on the hands and indices holds well into low light — appropriate for something pitched at field use. The green NATO with its brown leather loops wears casually but keeps the whole thing anchored to its working-watch intention rather than drifting toward dress territory.

Learn more about Hamilton
Hamilton was founded in Lancaster, Pennsylvania in 1892, and its early business was the railroad. American rail accidents caused by unsynchronised timekeeping had forced the industry to adopt strict standards, and Hamilton built pocket watches accurate enough to meet them — earning the description the watch of railroad accuracy.
Two things then defined it. The first was war: Hamilton supplied over a million watches to American forces in the Second World War, suspending civilian production entirely, and its marine chronometers were fitted across the US Navy.
The second was electricity. The Ventura of 1957 was the first battery-powered electric wristwatch, and its asymmetric shield-shaped case, designed by Richard Arbib, looked like nothing before it. Elvis Presley wore one in Blue Hawaii.
Hamilton's cinematic presence is unusually deep — over five hundred films — and includes the watches designed for 2001: A Space Odyssey with Stanley Kubrick, and appearances in Interstellar and Tenet.
American manufacturing ended in 1969 as the quartz crisis approached. The brand was acquired by the Swiss and is now part of the Swatch Group, based in Biel, where it occupies a distinctive position: American design heritage, Swiss production, and ETA movements with long power reserves at accessible prices. The Khaki Field, descended from the wartime issue watches, is its best-known line.

Your new watch
Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is hand-wound, so it needs winding every day or two but never a battery.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 80 hours fully wound — enough to sit off the wrist over a weekend and still be running.
What size strap does it take?
20mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 48mm, which suits wrists from roughly 16.5cm (6½ inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
