Frequently asked questions

What is the lug width of the Oris Artix 01 915 7643 4031-07 8 21 80?

The lug width of this model is 21 mm, measured as the internal distance between the two case suspension pins. This dimension is critical when selecting an aftermarket strap to ensure perfect compatibility and prevent structural stress on the case.

Which strap material do you recommend for the Oris Artix 01 915 7643 4031-07 8 21 80?

We recommend high-grade alligator with natural pronounced grain, or vegetable-tanned calf leather. Both maintain the technical, minimalist identity of this pilot's chronograph. Alternatively, cordura NATO or rubber-coated straps offer functional versatility without aesthetic compromise.

How do you change the strap on the Oris Artix 01 915 7643 4031-07 8 21 80?

Use a dedicated pin remover tool and a small watchmaker's hammer. Position the watch with the case back facing upward, insert the pin remover into the access seat and gently tap to push the pin outward. Repeat for both pins. Reverse the procedure with the new strap, ensuring pins are perfectly aligned.

Which aftermarket straps are compatible with the 01 915 7643 4031-07 8 21 80?

Any strap manufactured with a 21 mm lug width is compatible. Milano Straps offers a specialised collection of 21 mm straps in alligator, calf, shell cordovan, NATO and rubber, all tested to guarantee precise engineering tolerances and zero wear on Oris case lugs.

How long does a leather strap last on the Oris Artix?

A high-quality leather strap in vegetable tannage or alligator ensures 5 to 8 years of lifespan with regular daily wear. Longevity depends on exposure to perspiration, moisture and maintenance frequency (gentle cleaning, specific balms). The patina developing over time is a sign of quality and does not compromise structural integrity.
