Stepping up in the same colour and case shape
The Khaki Field traces its roots to the military-issue watches Hamilton supplied to American armed forces from the 1940s onward — a lineage that explains why this watch looks the way it does. The Arabic numerals, the 24-hour inner ring, the plain legible dial: these are functional decisions that have outlasted the contracts that first demanded them, and they still read immediately in dim light or under pressure. The H-10 movement is the detail that separates this from the rest of the field-watch category. Eighty hours of power reserve means a watch left on the nightstand Friday evening is still running Monday morning — a genuinely useful margin, not a marketing figure. The open caseback makes the rotor visible, and at 11mm the case is trim enough to sit beneath a cuff without catching. The Nivachron balance spring adds quiet resistance to the magnetic fields that stop lesser movements dead.

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.
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 automatic — the motion of your wrist winds it, and there is no cell to replace.
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?
22mm. 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 53mm, which suits wrists from roughly 17.5cm (7 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.
