Strap for Artelier Skeleton 40 Stainless Steel

The lug width is 21mm, measured as the internal distance between the two lugs on the case. Verifying this dimension before purchasing an aftermarket strap is essential, as even 1mm deviations compromise compatibility and fit.

For this 40mm stainless steel case, we recommend genuine alligator with even grain or vegetable-tanned calf leather that ages beautifully. For practicality, a dark blue or anthracite grey NATO maintains aesthetic restraint without functional compromise.

Remove the spring bars (small metal springs) positioned at the lug ends using a dedicated tool or spring bar tool. Insert the tip into the slot, gently compress the spring, and extract the lug from the old strap. Repeat on the opposite side, then thread the new strap through in reverse.

Yes, provided they are compatible with 21mm lugs. Artisanal-quality straps are an excellent choice for this model: they enable aesthetic personalisation whilst preserving the technical integrity of the case and movement.

A quality strap—whether alligator or vegetable-tanned calf—lasts 5 to 10 years with moderate wear (5–6 days weekly). Longevity depends on humidity exposure, frequency of strap changes, and maintenance care applied. Vegetable-tanned leather ages gracefully, developing patina, whilst synthetic materials have shorter lifespans.
