Strap for Audi Sport GMT Stainless Steel / Silver / Bracelet

The lug width of the Oris Artix GT 01 747 7701 4461-07 8 22 85 is 22mm. This measurement refers to the distance between the two holes of the lugs located on the right and left sides of the case. To verify compatibility, measure with a calliper the gap between the two holes: it must be exactly 22mm.

The ideal strap depends on your intended use. For formal wear and everyday use, we recommend alligator or vegetable-tanned leather in havana brown or black tones. For sportswear and water activities, a cotton NATO or FKM rubber strap offers practicality and breathability. The 44mm case pairs effectively with medium-grain texture and warm colours.

Changing the strap requires accessing the watch lugs. Use a spring bar tool to gently remove the pins securing the strap to the case. Insert the flat end of the tool into the narrow gap between the lug and the strap, lift slowly to release the internal spring, and slide out the pin. Repeat the procedure on the opposite lug. Installing the new strap follows the reverse process.

Yes, provided the aftermarket strap is constructed with a 22mm lug width and uses spring bars and springs of equivalent quality. Artisanal leather straps with vegetable tanning, high-density cotton NATO straps, and FKM rubber are completely compatible and do not compromise watch functionality. Always verify that spring bars and related components are made of stainless steel to prevent oxidation.

A vegetable-tanned leather strap of artisanal quality, subject to daily wear, maintains structural efficiency for 2 to 3 years. The surface patina (colour variation) begins to manifest after 6 to 8 months, an event testifying to the natural evolution of leather, not deterioration. Lifespan depends on exposure to moisture, frequency of use, and care. Periodic maintenance with natural waxes and thorough drying after perspiration significantly extends useful life.
