Strap for Artelier Date Diamonds 28 Stainless Steel / Silver

The lug width (ansa misura) of the Oris Artelier 01 561 7722 4031-07 5 14 65FC is 14mm. This measurement defines the internal distance between the two case lugs and is the fundamental parameter for strap compatibility. Precision is essential: measure internally between the lugs, not on their external surfaces.

For a 28mm case with 14mm lugs, we recommend a strap in alligator or European calf leather with vegetable tanning, thickness 1.4–1.6mm. These choices respect the case's delicate proportions and develop a natural patina over time. For versatile daily wear, a silk-cotton NATO or technical elastomer offers practicality whilst maintaining elegance. Casati Milano customises each strap to the precise geometry of your case lugs.

The strap is changed by extracting the spring bar (pin) that connects the lug to the case. Use a dedicated tool: position it beneath the spring bar, apply gentle upward pressure, then remove the strap from the lug. Insert the new strap, aligning the pin with the two small grooves, and press until you hear a click. Gentle, deliberate movements prevent case damage.

Yes, provided the lug width is precisely 14mm and the strap thickness is consistent (1.4–1.8mm for this case). However, not all suppliers maintain exact construction tolerances: Milano Straps and Casati Milano guarantee full Oris specification compliance and craft bespoke straps. An undersized strap causes unwanted movement; an oversized one may damage the lugs.

An alligator or vegetable-tanned calf strap, worn daily, maintains optimal function for 3–5 years. Longevity depends on wear frequency, humidity exposure, and maintenance (avoid stagnant water, condition occasionally with specialist creams). Leather naturally darkens, developing patina: this is not degradation but aesthetic evolution. Fabric NATO resists 4–8 years; buttero rubber 5–7 years with more uniform wear.
