Hamilton
Khaki Field H68201993— lug 20mm

The lug width of the Hamilton Khaki Field H68201993 is 20mm. This measurement is taken from the centre of one lug to the other, perpendicular to the case. It is essential to verify this dimension before purchasing an aftermarket strap, as an error would result in mechanical incompatibility.

For the Khaki Field, we recommend alligator straps with vegetable tanning (cognac or tobacco) for formal wear, or military NATO in cotton-nylon for practicality. For humid environments or sporting use, black FKM rubber offers maximum durability. The choice depends on your use case and desired aesthetic narrative.

The procedure is straightforward: equip yourself with a dedicated tool (spring bar tool or pin remover), position the watch horizontally, insert the tool into the small aperture beneath the lug to release the internal spring, extract the old strap, insert the new one by aligning the lugs, and press until you hear a click. Avoid forcing to prevent scratching the case.

Yes, provided the lug width is exactly 20mm. Artisanal straps in alligator, vegetable-tanned leather, NATO, and rubber from milanostraps.it are specifically dimensioned for this measurement and guarantee complete mechanical compatibility. Always check width specifications before ordering.

A quality leather strap (alligator or vegetable-tanned calf) has an average lifespan of 3–5 years with moderate use and proper maintenance: dry after water contact, avoid prolonged humidity exposure, periodically hydrate with specific products. Vegetable tanning develops natural patina that enhances perceived value over time.
