Strap for Artelier Skeleton 40.5 Stainless Steel - Yellow Gold

The lug width is precisely 21mm, measured between the two metal springs protruding from the case where the strap attaches. Selecting a strap with exactly 21mm width is essential to ensure proper fitment without gaps or forcing.

Alligator leather with vegetable tanning is the natural choice: the fine grain contrasts elegantly with the exposed movement. Vegetable-tanned calf leather represents an excellent alternative with beautiful patina development. NATO straps in neutral tones (navy, charcoal) enhance dial legibility. FKM rubber provides versatility across formal and casual settings.

Use a dedicated spring bar tool or consult an expert. Position the watch on a flat surface, locate the small metal pin beneath the lug, gently lever to compress the internal spring, remove the old strap, insert the new strap aligning the pins, and release. The operation takes two minutes with practice. Casati Milano offers professional mounting by appointment.

Yes, any strap with 21mm lug width is technically compatible. However, construction quality varies significantly. Quality aftermarket options (alligator, shell cordovan, vegetable-tanned calf) guarantee longevity and aesthetic coherence with the Oris skeleton character. Avoid straps with poor stitching or artificial finishes.

With daily wear, a quality leather strap (alligator, vegetable-tanned calf) lasts 3–5 years before replacement becomes necessary. Natural patina improves over time, but leather eventually weakens at the lug attachment points. Nylon NATO extends beyond 8 years. FKM rubber reaches 6–7 years. Proper maintenance (periodic cleaning, natural wax conditioning) significantly extends strap longevity.
