Strap for Khaki Field Automatic 40mm Green / Bracelet

The lug width of the Hamilton Khaki Field H70595163 is 20 millimetres. This measurement is crucial for selecting compatible straps: any 20 mm strap will fit correctly into the bayonet-style lugs of the case.

The choice depends on intended use. For daily elegance, alligator in medium brown or vegetable-tanned calf offer patina and prestige. For practicality and durability, cotton-satin NATO or natural rubber guarantee resilience without compromise. The ideal strap pairs functionality with aesthetics befitting the field watch DNA.

The H70595163 features bayonet-style lugs: position the new strap end into the horizontal slots, align, and rotate slightly until it clicks into place. Use a spring bar tool for precision operations. The procedure is reversible and requires no specialist skills.

Any strap with a 20 mm lug width is compatible. Online retailers and specialist ateliers offer options in alligator, calf, shell cordovan, NATO and rubber. Always verify lug width before purchase to prevent misalignment with the lugs.

Durability varies according to tanning method and usage. Superior-grade alligator resists 3–5 years under normal conditions; vegetable-tanned calf, benefiting from tannin, reaches up to 7 years. Exposure to moisture, heat and perspiration reduces longevity. Rubber maintains structural integrity for 5–8 years.
