Strap for Khaki Aviation X-Wind GMT Chrono Quartz Stainless Steel / Green

The lug width of the Hamilton Khaki Aviation H77932560 is 22mm. This measurement is standard for aviation timepieces in this dimensional category and provides balanced visual proportion on a 46mm diameter case.

This chronograph accommodates multiple materials: vegetable-tanned alligator for formal contexts, aniline calf for those desiring natural patina over time, recycled-material NATO for aeronautical authenticity, or FKM rubber for maximum operational impermeability. Choice depends on intended use and aesthetic preference.

The operation is executed by extracting the lugs: using a spring bar tool, compress the small spring located within each lug, freeing it from its seat. The new strap is inserted by positioning one lug first, then the other, ensuring the diameter is 22mm and that no lateral play remains.

Yes, provided the strap is specifically dimensioned to 22mm lug width. Milano Straps' artisanal straps in leather, NATO and rubber are manufactured to precise tolerances and guarantee immediate compatibility without modification or adaptation.

Leather strap longevity depends on usage, environment and tanning method. Vegetable-tanned calf, worn daily on a moderate, perspiration-protected wrist, resists structural failure for 2-4 years. Alligator, owing to denser fibre, extends to 4-6 years. Regular maintenance—damp cloth cleaning, rapid post-immersion drying, application of specific creams—significantly extends service life.
