Think of the Hamilton Khaki Field King on a steel bracelet as the field watch for people who want one watch to do everything. It shows the day and date, protects its crown with dedicated guards and moves from desk to trail without a strap change.

The black dial gives military time a starring role, pairing a 24-hour scale with the usual 12-hour numerals for a technical, purposeful look. Inside, the automatic H-40 caliber drives the day-date display and stores up to 80 hours of power, nearly double the market standard according to Hamilton. An open caseback shows off the rotor.

The stainless steel bracelet and folding clasp add weight and a more finished appearance to the 40mm case, which measures 11.15mm thick with 20mm lugs. Sapphire crystal and 50m water resistance make it suitable for daily wear in any weather.
