Hamilton Khaki Field Expedition 41mm Mens Watch Black Stainless Steel
Ref. H70315130
Sits in Hamilton’s upper tier here — more premium than three quarters of the Hamilton watches we list, which start at £375.
Price range £375 to £2,265 across 72 Hamilton watches in stock.The Khaki Field line has long drawn on Hamilton's history of supplying military-grade instruments to armed forces, and the Expedition is where that brief gets taken furthest. Its distinguishing feature within the current range is the bidirectional compass bezel — no other Khaki Field in production carries one — paired with a screw-down crown that lifts the water resistance to a meaningful 100 metres. The result is a field watch that can be taken seriously outdoors rather than merely looked the part. At 41mm the case sits comfortably without demanding a large wrist, and the 48mm lug-to-lug keeps it seated rather than bridging. The compass bezel and the high-contrast satin dial add enough visual presence that the watch reads slightly larger than its measurements, which is not a criticism — it suits the character. The H-10 calibre inside is worth noting beyond its 80-hour power reserve: the Nivachron hairspring, a Swatch Group alloy, holds its rate against both magnetic fields and temperature swings, making it more resistant to the conditions the watch was designed for than most movements at this level. The syringe hands carry Super-LumiNova well; the printed Arabic numerals are somewhat less assertive in darkness, something an owner will observe in the first week.

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.

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 automatic — the motion of your wrist winds it, and there is no cell to replace.
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.
