Strap for Artelier Date 40 Stainless Steel / Black

The lug width is precisely 21.00 mm. This measurement defines the internal distance between the two attachment lugs on the case. A 21mm strap is the only compatible option for this model. Always verify this specification when purchasing an aftermarket strap, as variations of ±0.5mm can cause fitting issues.

Alligator leather with vegetable tanning is the primary aesthetic choice, as its fine grain and natural patina dialogue with the case's sobriety. Vegetable-tanned calf leather is the versatile daily alternative. For sport use, cotton or linen NATO is appropriate. FKM rubber suits humid environments and dynamic activities. Your choice depends on intended use and the patina development you prefer over time.

Remove the spring bars using a dedicated tool or seek assistance from a professional. Insert the new strap ensuring the lug width (ansa) is exactly 21mm. Reinsert the spring bars until the click-lock engages. If inexperienced, have the operation performed by an authorised service centre or specialised artisan to avoid damaging the case.

Yes, absolutely. The Oris Artelier 01 733 7591 4054-07 5 21 71FC accepts any 21mm strap, provided it does not exceed 4.2mm thickness at the lug attachment for smooth insertion. On milanostraps.it you can choose among handcrafted leather, NATO, and rubber straps—all certified compatible with 21mm lug width and customisable to your aesthetic preferences.

Durability depends on tanning type and usage patterns. A quality vegetable-tanned calf strap (such as those offered on milanostraps.it) typically lasts 3–5 years under moderate daily use. Vegetable-tanned alligator may reach 5–8 years due to its more robust structure. The natural patina that develops is part of the intended ageing process. Humidity, frequency of wear, and maintenance influence longevity; planned replacement every 4–5 years is prudent for a watch of this construction quality.
