The Khaki Navy H78595913, seen from the bench

The Hamilton Khaki Navy H78595913 combines American military aesthetics with Swiss robustness, evolved from Hamilton's historic Khaki collection for exploration and critical operations. The 42mm stainless steel case features a navy blue dial with applied Arabic numerals and baton indices for maximum legibility. It houses an ETA caliber 2824-2 movement with 4 Hz balance, manual and automatic winding, and approximately 38 hours of power reserve. The 22mm lug width is precisely calibrated for this case diameter to ensure ideal proportions between case mass and wrist comfort.

Frequently asked questions

What is the lug width of the Hamilton Khaki Navy H78595913?

The lug width of the H78595913 is 22 millimetres. This dimensional standard creates the ideal proportional balance between the 42mm case and wrist comfort. To verify, measure the distance between the two spring bar pins using a digital caliper: it should measure exactly 22mm from the centre of one to the centre of the other.

What is the best strap for the Hamilton Khaki Navy H78595913?

There is no universal answer; it depends on intended use. Vintage alligator leather maintains contained elegance without compromising tactical character; a blue navy NATO strap restores historical military authenticity; vegetable-tanned leather develops visible patina over time; satinised rubber is the contemporary choice for humid environments. All are compatible with the 22mm lug width.

How do I change the strap on my Hamilton Khaki Navy H78595913?

Use a spring bar tool (strap change lever). Insert the tip into the small slot beside the spring bar pin and press gently downward to compress the internal spring. The pin will retract, allowing you to extract the strap. Repeat on the opposite side. For installation, load the new strap by pressing the pins into the corresponding recesses on the case.

Which aftermarket strap is compatible with the Hamilton Khaki Navy H78595913?

Any strap with a 22mm lug width is compatible. Always verify that the strap has the correct spring bar pin housings. Artisanal leather straps, technical NATO straps and sports rubber straps in 22mm fit the H78595913 case without modification. Avoid different sizes (20mm or 24mm) to preserve the original constructive fit.

How long does a leather strap last on the Hamilton Khaki Navy H78595913?

A quality leather strap with vegetable tanning maintains structural integrity for 3–4 years with daily use and proper care (gentle cleaning, drying, occasional treatments). Patina and ageing marks are natural and increase aesthetic value. In marine or humid environments, durability reduces to 18–24 months; in such cases, opt for NATO or rubber alternatives.
