Strap for Artelier Skeleton 40.5 Diamonds Stainless Steel / Bracelet

The lug width of this model is precisely 21 millimetres. This dimension determines the univocal compatibility of aftermarket straps. We recommend measuring it with a digital calliper, positioning it perpendicularly between the two lugs of the case, from the outermost point of one lug to the outermost point of the other. A correct measurement should yield a result between 20.5 and 21.5 millimetres.

The best choice depends on your context of use and wardrobe. For formal and professional environments, we recommend alligator with vegetable tanning or structured calf leather: these materials amplify the authority of the case whilst maintaining visibility of the skeletonised calibre. For versatile daily wear, smooth calf in medium brown tone creates visual equilibrium. For casual or sporty environment, a NATO strap in cotton-nylon fabric offers practicality and calibrated contrast. Shell cordovan represents an excellent option for those frequenting humid environments, as its natural density renders it resistant to moisture.

Changing the strap on the 01 734 7670 4019-07 8 21 77 model requires extraction of the lug pins (springbars). Position the watch on a flat surface, then use a spring bar tool (a special instrument readily available online or at jewellery shops) to push the small horizontal metal pin downwards. The pin will retract, allowing you to lift the lug and remove the strap. Insert the new strap in the same manner, ensuring the pin clicks fully into the locked position. Verify that the strap is correctly aligned before wearing the watch again.

Yes, absolutely. Because the lug width is 21 millimetres, you may use any quality artisanal strap compatible with this measurement. High-quality aftermarket straps (made from alligator, calf, shell cordovan or technical fabrics) maintain compatibility with the original Oris lugs. We recommend choosing materials and colours that visually dialogue with the stainless steel case and skeletonised movement, preserving the sober aesthetic grammar of the model.

The lifespan of a natural leather strap depends on tanning quality, intensity of use and environmental conditions. An alligator or vegetable-tanned calf strap, used daily under normal conditions, maintains structural and aesthetic integrity for 3–5 years before requiring replacement. In humid environments (gymnasium, swimming pool, tropical climate), lifespan reduces to 2–3 years. Shell cordovan, by virtue of its natural density, offers superior durability (5–7 years). To extend useful life, we recommend alternating the strap with others (allowing leather to dry completely) and occasionally applying leather conservation products (natural waxes, not chemical solvents).
