Strap for Khaki Aviation Air Race 38 Auto Black / Bracelet

The lug width is 19 mm. This measurement is taken by placing a precision ruler inside the spring bar from corner to corner. When purchasing an aftermarket strap, this dimension must match exactly; manufacturing tolerances allow maximum variations of ±0.5 mm.

It depends on intended use and desired aesthetic. Natural alligator or vegetable-tanned calf leather enhance elegance; a NATO strap in khaki or olive green emphasise the military aviation heritage; vulcanised rubber is the technical choice for extreme environments. Quality artisanal 19 mm straps in all these materials are available on milanostraps.it.

The H76235131 uses a spring bar system. Obtain a dedicated tool (strap remover or spring bar tool) to gently release the spring from one side, remove the metal bar, and replace the strap. It is advisable to keep two quality replacement spring bars; avoid excessive force that could damage the mounting seats on the case.

Yes, provided the lug width is exactly 19 mm and the fastening system is identical (standard spring bar). The artisanal straps from milanostraps.it are manufactured with the precision tolerances necessary to guarantee perfect fit without lateral play or excessive tension.

Durability depends on material and tanning method. A superior quality vegetable-tanned calf strap, with periodic maintenance (cleaning, conditioning with natural oils), maintains structural integrity for 5-7 years of daily wear. Alligator is more resistant and can last 8-10 years. The aesthetic aspect (patina, colour) changes progressively from the first year, developing the surface richness sought by watch enthusiasts.
