Strap for Artelier Small Second Date 40 Stainless Steel / Black - Silver

The lug width of the Oris Artelier 01 623 7582 4054-07 5 21 71FC is 21mm. This is a specific measurement, less common than the 20mm or 22mm found on other Oris models. This dimension represents the internal distance between the two lugs of the case where the strap attaches. To verify it with precision, use a digital calliper to measure the inner space between the two lateral protuberances on the case.

The Oris Artelier 01 623 7582 4054-07 5 21 71FC, given its elegant proportions and satin-finished case, pairs optimally with leather (calf, alligator or shell cordovan) at 1.4–1.5mm thickness for a formal and sophisticated look. For daily or casual wear, a cotton-polyester NATO at 1.6–1.8mm offers practicality without aesthetic compromise. A quality FKM rubber with matte finish is ideal for those seeking versatility and durability. Avoid low-cost synthetics: the Artelier's proportions demand tangible materials.

The strap is changed by removing the spring bars that connect the strap to the case lugs. To do this correctly: 1) position the watch on a soft surface (microfibre cloth); 2) use a dedicated spring bar tool or small flat screwdriver to gently push the bar towards the centre of the case, easing tension; 3) once the bar disengages from one lug, remove the old strap; 4) insert the new bar into the holes of the new strap's lugs and push it into the case slots until it clicks. Precise movements without excessive force protect the lug threads.

Yes, any strap with a 21mm lug width (especially those from quality artisanal brands such as those offered by MilanoStraps) is compatible with the 01 623 7582 4054-07 5 21 71FC, provided the spring bar profile matches the original and the strap is not overly rigid, which could place excessive stress on the lugs. Aftermarket leather, rubber or technical textile straps often represent an opportunity to personalise your watch according to your style. Always verify that the internal width is exactly 21mm before purchase.

The durability of a leather strap depends on the tanning type, usage and maintenance. A vegetable-tanned calf of good quality, at 1.4–1.5mm thickness, offers a lifespan of 3–5 years with moderate daily wear (4–5 days per week). Alligator and shell cordovan, being denser and more compact leathers, can reach 5–7 years. Frequent exposure to water, perspiration and sunlight shortens strap life; conversely, rotation with other straps and regular drying extends it. A natural patina (slight darkening and softening) emerges after 12–18 months of wear: this is not deterioration, but aesthetic evolution of living leather that characterises artisanal quality materials.
