Strap for Artelier Date 40.5 Stainless Steel - Rose Gold / Silver

The lug width is 21 mm, which represents the distance between the two lugs (pins) that attach the strap to the case. This is a precise measurement that requires straps specifically manufactured for this width. A 20 mm strap would be too narrow, whilst a 22 mm strap would be too wide for proper fit.

The choice depends on intended use and aesthetic preference. For formal elegance, we recommend alligator or vegetable-tanned calf leather in dark tones (brown, black, burgundy). For daily versatility, NATO straps in black or pearl grey offer quick-change practicality. Technical rubber is ideal for sporting or casual contexts. All materials must be manufactured for the 21 mm lug width specification.

The strap is changed by removing the lugs using a spring bar removal tool. This specialised instrument allows you to depress the internal elastic pin that secures the lug to the case. Once the space is cleared, the strap slips away easily. Reinsertion follows the reverse procedure, ensuring the elastic pin is fully retracted. If you are inexperienced, we recommend consulting an authorised service centre.

Yes. Aftermarket straps manufactured for the 21 mm lug width are fully compatible. It is essential to verify that the strap is certified for this exact width specification; reputable manufacturers provide clear dimensional data. Milanostraps.it offers a selection of artisanal straps in leather, NATO and rubber, all compatible with your Oris model.

Durability depends on use and maintenance. A quality leather strap, worn daily, maintains structural integrity for 3–5 years. Factors that accelerate wear include perspiration, moisture, direct UV exposure, and repeated flexing. Natural leather develops a patina (natural colour variation over time) that characterises its authenticity. To extend lifespan, we recommend drying the strap after use and occasionally applying protective natural waxes.
