Frequently asked questions

What is the lug width of the Oris Artelier 01 781 7729 4031-07 5 21 32FC?

The lug width of this model is 21mm. This dimension represents the internal distance between the case lugs where the strap is fitted. It is essential to verify this measurement before purchasing an aftermarket strap to ensure perfect alignment and correct mechanical attachment.

Which strap is most suitable for the Oris Artelier?

Given the elegant and sober nature of the model, we recommend shell cordovan with vegetable tanning in dark brown, or black alligator for more formal contexts. Both materials amplify the constructive solidity of the watch. For greater versatility, a heavy cotton NATO in dark grey offers practicality without aesthetic compromise.

How do I change the strap on my Oris Artelier?

To change the strap, use a spring bar tool. Insert the tip of the tool into the small lateral hole of the clip spring, press gently to release the lug on one side, then remove the used strap. Align the new strap with both lugs and press until you hear a confirmation click. Never use improvised sharp objects, as they may damage the case.

Is there a compatible aftermarket strap for the 21mm lug width?

Yes, straps with 21mm lug width are available in various finishes and materials. At milanostraps.it you can find a specialist selection of leather (alligator, shell cordovan, calf), NATO fabric, and technical FKM rubber, all calibrated for this specific width.

How long does a leather strap last on a watch like the Oris Artelier?

A quality leather strap with vegetable tanning typically lasts 3-5 years under normal wear conditions. Durability depends on the type of leather: shell cordovan, being thicker and more resistant, tends to last longer. Direct sun exposure, humidity, and continuous wear accelerate ageing. Proper maintenance—periodic cleaning and removal when not worn—significantly extends the strap's lifespan.
