Which Khaki Should You Buy? Hamilton Khaki Field vs Khaki Aviation
Serdar D.Watch EditorChoose the Khaki Field if you want a compact, legible everyday watch: 38 to 42 mm cases, a choice of quartz, hand-wound H-50 or automatic H-10, and prices from under $450 up to about $1,100. Choose the Khaki Aviation for a larger pilot dial, a day-date or a chronograph, with 100 m water resistance across the line and prices from about $1,075 to $2,095.
Editor's verdict
If you want one compact watch for every day, the automatic Khaki Field 38mm (H70455533) gives you the H-10 movement and a 100 m rating at a midrange price, while the hand-wound H-50 models suit buyers who enjoy the ritual of winding. For a pilot dial with day and date, the Khaki Aviation 42mm (H64615735) is the sensible pick. Chronograph fans should go for the H-21 Khaki Aviation 44mm, and budget buyers should start with the quartz Khaki Field.
Key takeaways
- The Khaki Field models here measure 38 to 42 mm, while the Khaki Aviation models range from 38 to 45 mm.
- The Field line offers quartz, hand-wound H-50 and automatic H-10 or H-40 movements, starting at around $400 to $450 on Amazon US.
- Every Khaki Aviation model listed is rated to 100 m; Field models are split between 50 m and 100 m.
- For a day-date or a chronograph you need the Aviation line, and the only titanium case here is a 38 mm Khaki Field.
Khaki Field vs Khaki Aviation at a Glance
Both lines come from Hamilton, which was founded in 1892 in Lancaster, Pennsylvania, and is now part of the Swatch Group, headquartered in Biel/Bienne, Switzerland. The Khaki Field takes its look from the watches Hamilton supplied to the US armed forces during both World Wars. The Khaki Aviation line follows the pilot watch style, with cases up to 45 mm and day-date or chronograph options.
The short answer: pick a Khaki Field if you want a compact, legible field watch for everyday wear. Go for a Khaki Aviation if you want a bigger pilot dial, a day-date display or a chronograph. The price ranges in this guide reflect Amazon US in October 2026; since prices change, check the product cards for current pricing.
Case Sizes and Proportions
The Khaki Field models here run from 38 to 42 mm. Most are 38 mm with 20 mm lugs and thicknesses between 8.3 and 11.5 mm, proportions that usually suit slimmer wrists. The Khaki Field 42mm (H70555533) is the larger option, with 22 mm lugs and a listed thickness of 8 mm. One Field reference also comes in a titanium case, which is lighter than steel.
The Khaki Aviation models span 38 to 45 mm. The Khaki Aviation 38mm (H76205530) is the compact choice, with 18 mm lugs, while the X-Wind reaches 45 mm and the chronograph is 15.6 mm thick. If you're not sure which diameter will fit, our guide on how to size a watch walks you through measuring your wrist.
Movements Compared
The Field line offers the widest range of movement options. The quartz Khaki Field 38mm (H69401430) runs on an ETA F06.111 battery movement. Two 38 mm references use the hand-wound H-50, several use the automatic H-10, and the 40 mm H64455533 pairs the automatic H-40 with a marked bezel.
The Aviation line is all mechanical: the H-10 in the 38 mm model, the H-40 with day and date in the 42 mm, the H-30 with day and date in the X-Wind, the H-21 in the chronograph and a hand-wound ETA 6498-1 in the 43 mm Pilot. Hamilton rates the H-10, H-30, H-40 and H-50 at 80 hours of power reserve and the H-21 at 60 hours, while the ETA 6498-1 listing states 50 hours.
A hand-wound watch needs a few turns of the crown every couple of days; an automatic winds itself as you wear it. If you're still deciding between a battery and a mechanical movement, read automatic vs quartz.
Water Resistance, Crystals and Price
Every model in this comparison has a sapphire crystal, so neither line has the edge there. Water resistance is where they part ways: every Aviation model is rated to 100 m, while the Field models are either 50 m (quartz, H-50 and the 40 mm H-40) or 100 m (the H-10 automatics). A 50 m rating is fine for splashes and light swimming, and 100 m gives you more margin, but neither is a dive watch rating.
Price is the other big gap. The Field line starts at around $400 to $450 and tops out at around $1,050 to $1,100, which is right where the Aviation line begins.

Which One Is Right for You
The Cheapest Entry Point
The quartz Khaki Field 38mm is the least expensive way into the family, at around $400 to $450. It's 8.3 mm thick, has a sapphire crystal and never needs winding.

View productThe Hand-Wound Pick
The black-dial Khaki Field 38mm (H69439931) pairs the H-50 with a 9.5 mm case and a nylon strap. If you'd rather have a white dial on brown leather, the Khaki Field 38mm (H69439511) has the same specs. For a big hand-wound pilot watch, the Khaki Aviation Pilot (H76719530) puts the ETA 6498-1 in a 43 mm case.

View productThe Automatic Pick
Our pick here is the Khaki Field 38mm (H70455533): H-10 automatic, 100 m, 20 mm lugs, around $750 to $800. The Khaki Field Murph (H70405730) has similar specs and is based on the watch Hamilton made for the 2014 film Interstellar. The Khaki Field 40mm (H64455533) adds a marked bezel but drops to 50 m.

The Khaki Aviation 42mm (H64615735) gives you day and date from an H-40 automatic in a 42 mm case. For an even larger dial, the X-Wind (H77755533) uses the H-30 with day-date at 45 mm. You'll find more options on our pilot watches page.

The Khaki Aviation 44mm (H77616533) is the only chronograph here. It runs on the H-21 with 60 hours of power reserve and has a drift-angle calculator bezel, but at 15.6 mm thick it's also the bulkiest model.

Start with your wrist size and the complications you want. If you want 38 mm, three hands and the lowest price, stay with the Field line. If you need a day-date, a chronograph or 100 m across the board, move to the Aviation line.
