Frequently asked questions

What is the lug width of the Oris Artelier 01 733 7591 4091-07 8 21 73?

The lug width of this Artelier model is 21.00mm. This measurement represents the internal distance between the two lug terminals, calculated at the point where the watch strap lugs are installed. It is a precise dimension and not interchangeable with more common standards such as 20mm or 22mm.

Which strap do you recommend for the Oris Artelier 01 733 7591 4091-07 8 21 73?

For this watch, we recommend a vegetable-tanned alligator leather strap, which enhances the case proportions and creates aesthetic contrast with stainless steel. Alternatively, structured calf leather in dark tones (brown, black, burgundy) guarantees elegance and everyday durability. For more versatile use, a robust cotton NATO strap maintains formal sobriety without compromise.

How do I change the strap on my Oris Artelier 01 733 7591 4091-07 8 21 73?

The side lugs of the Artelier feature small recesses that hold the strap in place. Using a spring bar tool or small lever, compress the elastic terminal of the lug to create space and slide the old strap outward. Insert the new strap in the same position, ensuring that the lug shoulders fit perfectly into the case recesses.

Can I use an aftermarket strap with my Oris Artelier 01 733 7591 4091-07 8 21 73?

Yes, absolutely. Any strap with a 21mm lug width is completely compatible with this model. Artisanal aftermarket straps, such as those from milanostraps.it, often offer superior construction quality compared to OEM straps and allow you to fully personalise your watch's aesthetics while maintaining precise installation accuracy.

How long does a leather strap last on the Oris Artelier 01 733 7591 4091-07 8 21 73?

A quality vegetable-tanned leather strap, under normal daily-use conditions, typically lasts 24-36 months. This duration depends on exposure to moisture, frequency of use, and maintenance (drying after water contact, occasional conditioning). An alligator strap tends to last longer due to the robustness of the leather. NATO textile straps have potentially unlimited lifespan, requiring only periodic cleaning.
