Stepping up in the same colour and case shape
The Khaki Field traces directly to the watches Hamilton supplied to the American military from the Second World War onwards, and this iteration keeps faith with that brief in every material choice: the matte-finished steel case, the olive dial marked in both 12- and 24-hour increments, the canvas NATO strap with leather backing. There is nothing on the dial that a soldier in poor light would not need, and nothing missing that one would. At 38mm with a case thickness of 9.5mm, it sits flat and unobtrusive under a sleeve, and the 47mm lug-to-lug distance means it will fit a wider range of wrists than most field watches at this diameter. The H-50 movement inside is wound by hand, which rewards the habit of a daily ritual and offers 80 hours of reserve for those who do not keep one — enough to cover a long weekend without touching the crown.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
No. It is hand-wound, so it needs winding every day or two but never a battery.
How 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 47mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as men's, though at 38mm it sits in the range that suits anyone.
