Strap for Artelier Skeleton 40 Stainless Steel / Bracelet

The lug width of the model 01 734 7670 4051-07 8 21 77 is precisely 21mm. This measurement corresponds to the distance between the two stainless steel lugs that connect the watch case body to the strap. It is the fundamental parameter for verifying the compatibility of any aftermarket strap before purchase.

The choice depends on the intended use and aesthetic preferences. For formal contexts, we recommend a strap in alligator or Taurillon calf leather with vegetable tanning, which develop natural patina over time and impart discreet elegance. For daily use and practicality, a NATO strap in polyamide offers durability and reversibility. For humid environments or outdoor activities, natural rubber ensures longevity without moisture absorption.

The strap is replaced by removing the lugs: using a dedicated tool (spring bar tool), apply pressure inward to release the internal spring of the lug, allowing vertical sliding of the lug from the strap. Once removed, insert the new strap (21mm lug width) and repeat the process in reverse. Simple work requiring approximately two minutes and no specialist knowledge.

Yes, any strap with a 21mm lug width is compatible with this model. The Oris case does not use proprietary lugs, which allows maximum versatility. Before purchase, always verify that the strap explicitly declares 21mm as the lug width, and check that the thickness of the leather or material is not excessive (maximum 2-2.5mm recommended for easy access to the lugs).

Longevity depends on the material, tanning method, and intensity of use. A calf strap with vegetable tanning maintains structural functionality 3-5 years with daily use, developing visible patina over time. Shell cordovan, being more resistant, surpasses 7-10 years. Replacement is recommended when the leather begins to lose flexibility, visibly cracks, or the buckle shows wear. Alternating with other straps significantly extends the life of each one.
