The Heritage

The Hamilton Khaki Field H79745583 is a 51.60mm titanium tool watch featuring the automatic ETA 2824-2 caliber with 28,800 vph and over 40 hours power reserve. Bold dial indices and sword hands ensure readability in critical conditions, while the screw crown and recessed secondary crown protect internal mechanisms. Grade 5 titanium offers 60% less weight than stainless steel and superior corrosion resistance, with 100m water resistance. The 35mm lug width provides visual balance on this oversized case and ensures compatibility with standard watch straps.
Made to Measure

The strap for this watch is made to measure

On the Hamilton Khaki Field the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

What is the lug width of the Hamilton Khaki Field H79745583?

The Hamilton Khaki Field H79745583 features 35mm lugs. This specification is standard for this model and ensures full compatibility with all 35mm straps in the Milano Straps catalogue.

Which strap is most suitable for the Hamilton Khaki Field H79745583?

Selection depends on intended use. For pure tactical vocations: robust nylon NATO or FKM rubber strap. For operative elegance: vegetable-tanned European calf leather, dark brown or black. For historical fidelity: alligator grain with marked texture. Shell cordovan, though refined, creates stylistic dissonance with the aggressive character of the titanium case.

How do I change the strap on my Hamilton Khaki Field H79745583?

The straight 35mm lugs feature lateral spring bars. Position the watch on a soft cushion (dial downward), gently unscrew the spring bar on one side using a lug remover tool, slide the old strap off, insert the new strap aligning it with the lugs, reinsert and screw the spring bar until secure.

Can I fit an aftermarket strap from different brands on my Hamilton Khaki Field H79745583?

Yes, any strap with a 35mm lug width is compatible with the Khaki Field. Milano Straps offers a curated selection of artisanal straps in leather, alligator, NATO and rubber, all tested for fit and durability. Before purchase, verify that the strap is not fitted with an integrated deployant clasp, which would be incompatible with the straight lugs of the H79745583.

How long does a leather strap last on a watch like the Hamilton Khaki Field H79745583?

Longevity depends on tannage, hydrophobic treatment and usage patterns. A calf strap with vegetable tanning, worn occasionally, lasts 3–5 years. Alligator, more structurally resistant, achieves 4–6 years. Rubber and nylon NATO exceed 5–7 years. Prolonged exposure to moisture, acidic perspiration and direct sunlight significantly reduces these intervals.
