Strap for Khaki GMT Air Race

The lug width is 21 mm. This measurement corresponds to the distance between the lugs of the case, measured from the inner shoulder of one lug to the other. It is essential for selecting compatible straps without mechanical play or structural tension.

We recommend an alligator strap with vegetable tanning to emphasise the rifle dial with natural patina over time, or Hermès calf for daily versatility. For intensive aviation use, a cordura ballistic NATO provides quick changes and moisture resistance. FKM rubber is ideal if frequently exposed to perspiration.

Gently remove the spring bar securing the strap to the lugs using a specific extraction tool. Remove the old strap, insert the new one by aligning the holes with the spring bar, and secure the fastening. A task of mere seconds requiring no laboratory visits.

Yes, provided they respect the 21 mm lug width. Straps of lesser width (20 mm) or greater width (21.5 mm) would cause instability. Always verify technical specifications before purchase and privilege quality materials (alligator, vegetable-tanned calf, ballistic textiles) for aesthetic coherence with the satin case.

A quality leather strap (alligator, calf, shell cordovan) lasts 3–7 years with ordinary maintenance and moderate use. The patina deepens naturally, improving appearance over time. Factors such as humidity, perspiration, frequency of use, and care influence longevity. Regular application of protective balm significantly extends durability.
