Strap for Artelier Complication 40.5 Stainless Steel - Yellow Gold / Silver

The lug width of the Oris Artelier 01 582 7689 4351-07 1 21 73FC is 21 mm. This is the distance between the case lugs that anchor the strap. To verify strap compatibility, measure the space between the two lugs: it must be exactly 21 mm. A lug width of this dimension represents the ideal compromise between the 40.50 mm case and proportions suitable for the average male wrist.

The ideal strap depends on intended use. For formal elegance, alligator with fine grain texture in dark brown or black is recommended: premium leather enhances the Artelier's sobriety. For daily wear with patina development, vegetable-tanned calf is excellent. For versatile informal use, cotton sateen NATO. For humid climates, high-quality FKM rubber. At milanostraps.it you will find handcrafted 21mm straps in all these variants.

Changing the strap on the Oris Artelier requires a simple tool: a spring bar tool (instrument for extracting elastic pins). Position the watch on a soft surface to prevent scratches, insert the tool into the lateral spaces of the case to compress the elastic pin, then extract the worn strap. Insert the new 21mm strap by aligning the holes, reinsert the elastic pin until it clicks into place. If you are not experienced, Casati Milano offers strap-change service by appointment.

Yes, you can use aftermarket straps provided they respect the 21 mm lug width specification. Always verify the declared width from the manufacturer. Artisanal quality straps (leather, NATO, or rubber) are fully compatible. We recommend choosing manufacturers that guarantee precise construction tolerances: at milanostraps.it every 21mm strap is tested for fit and security.

Lifespan depends on material and usage. High-quality alligator or calf leather, with ordinary care (avoid prolonged immersion, dry after humidity exposure), lasts 5-8 years. Leather develops natural patina over time, which increases aesthetic value. To extend life, apply protective balms every 6-12 months and avoid direct heat sources. Textile NATO straps last longer (10+ years) if handled carefully. Casati Milano recommends ordinary maintenance to maximise longevity.
