Strap for Oris Artelier 01 749 7667 4051

The Oris Artelier 01 749 7667 4051 features a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 21mm. This measurement is the standard for 40mm steel timepieces and ensures a proportional balance between case and strap. To verify the compatibility of an aftermarket strap, measure the distance from the centre of the first lug hole to the centre of the last: it must be exactly 21mm.

For a dress watch of this elegance, Mississippi <a href="/pages/termine-glossario/alligatore">alligator</a> in cognac brown is the natural choice. The regular texture and fine grain of the reptile skin coordinate perfectly with the silver-satin dial and steel without introducing visual discord. Alternatively, a calf leather with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> in burgundy offers visible ageing and organic patina over time whilst maintaining formality.

The strap is secured to the lugs via spring bars (strap pins). To remove the original strap: 1) use a small screwdriver (preferably a dedicated watch tool) to push the spring bar laterally; 2) extract the spring bar from the first side; 3) repeat on the other side; 4) remove the strap. To install the new 21mm strap: 1) insert the spring bar into the first lug hole; 2) align the strap with the lugs; 3) secure the spring bar in the second hole. Proceed with care to avoid scratching the case.

Any strap with a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 21mm is compatible with this model. We recommend straps in alligator, calf, structured FKM rubber or natural rubber of high quality. On milanostraps.it you will find a selection of artisan-crafted 21mm straps with internal rubber lug padding and finished edges that respect the aesthetic of the timepiece.

The lifespan of a leather strap depends on frequency of wear, climatic conditions and quality of tanning. A quality alligator or calf strap, worn daily, has a service life of 3–5 years before replacement is required for structural reasons. <a href="/pages/termine-glossario/concia-vegetale">Vegetable-tanned</a> leather tends to maintain longevity better than industrially chrome-tanned straps, as it develops a patina that masks natural abrasion. Prolonged exposure to moisture, perspiration and ultraviolet radiation accelerates aging.
