Strap for Artelier Hand Winding Small Second 40 Stainless Steel / Silver

The lug width of the Oris Artelier 01 396 7580 4051-07 5 21 05 is exactly 21mm. This measurement is taken internally between the two metal lugs that anchor the strap. A compatible strap must be precisely 21mm wide to fit correctly without play or forcing.

This Swiss timepiece is best paired with straps in alligator or calf leather with vegetable tanning, which respects the aesthetic integrity of the stainless steel case. A sporty NATO canvas option is ideal for daily wear, whilst FKM rubber suits aquatic environments. Choice depends on intended use: formal (leather), versatile (NATO), aquatic (rubber).

Changing the strap requires a spring bar tool to extract the elastic pins from the lugs. Position the tool beneath the strap's lug end, apply gentle upward pressure until the spring bar retracts, then remove the strap. Insert the new 21mm strap by aligning it with the lugs and allowing the spring bars to re-engage into position.

Yes, any strap with a 21mm lug width is compatible with reference 01 396 7580 4051-07 5 21 05. Verify that the strap is specifically 21mm and not 20mm or 22mm. Artisanal quality straps maintain construction tolerances conforming to the 21mm specification.

A vegetable-tanned leather strap typically lasts 3-5 years with regular maintenance. Prolonged exposure to direct sunlight and humidity reduces longevity. Vegetable-tanned leather develops natural patina over time and can be rejuvenated with specialist oils, extending the strap's lifespan compared to conventional chrome-tanned leathers.
