Strap for Artelier Calibre 111 Stainless Steel / Silver

The lug width is 23mm, a non-standard dimension that requires bespoke or artisanal straps. This deliberate choice by Oris means that owners must carefully source compatible straps, excluding conventional sizes such as 20mm or 22mm. Measurement is performed by positioning a digital calliper between the two horizontal lugs on the case.

Alligator leather with vegetable tanning represents the most aesthetically coherent choice: the pronounced grain creates perfect visual dialogue with the understated brushed steel case. Grained calf leather is an equally elegant alternative that visibly evolves over time, developing a unique patina. For versatility, heavyweight cotton NATO offers practicality whilst maintaining formal proportions. Butadiene rubber remains ideal for dynamic contexts.

Replacement requires specific tools: a quality spring bar tool to prevent case damage. Position yourself at an angle to the lug, insert the tool into the small gap beneath the lug and compress the internal spring. Once the pin is released, extract the old strap and insert the new one, ensuring that the lugs position correctly on the attachments. If inexperienced, professional fitting at a horologist guarantees precision and safety.

Yes, provided the strap is certified for 23mm lug width and the lugs are dimensionally correct. Not all manufacturers offer this specific size, as 23mm falls outside industrial standards. We recommend always verifying exact compatibility with the vendor before purchase, measuring the lugs and confirming the actual width between the attachments.

A high-quality alligator or calf strap, if properly maintained, typically lasts 3–5 years of daily wear. Longevity depends on factors such as humidity, sunlight exposure, cleaning frequency, and treatment with nourishing creams. Well-treated leather not only lasts longer but also improves aesthetically, developing patina and character. Natural deterioration is part of the beauty of authentic leather.
