Strap for Artix Pointer Moon Date Stainless Steel / Black

The Oris Artix 01 761 7691 4054-07 5 21 81FC is equipped with 21mm lugs. This measurement is specific and requires 21mm-compatible straps; it is not interchangeable with 20mm or 22mm standards. Correct measurement is performed with a digital calliper, positioning the measuring shoulders on the inner walls of the lugs, excluding the spring bar pin.

For the Artix 01 761 7691 4054-07 5 21 81FC, we recommend three primary options: Mississippi alligator for formal and ceremonial contexts, with vegetable tanning and evolving patina over time; shell cordovan for daily wear, offering superior robustness and pronounced aging; ballistic NATO for sporting and unstable climatic contexts. The choice depends on attire, season, and frequency of use.

Strap replacement requires two tools: a spring bar tool and natural light or a magnifying lens. Position the watch with the lugs facing upward, insert the spring bar tool into the lateral opening of the spring bar, press toward the centre to compress the spring, and extract the pin. Repeat on the opposite side. Insert the new strap by aligning the holes, then reposition the spring bars by exerting pressure until the click lock engages.

All 21mm lug-width straps are compatible: full-grain leather straps (alligator, calf, shell cordovan), NATO and tactical NATO straps in polyamide, FKM rubber and technical silicone straps, ballistic textile straps. 20mm, 22mm, or other widths are not compatible. The construction quality and materials of Casati Milano guarantee durability and fit without mechanical stress on the case.

The lifespan of a leather strap depends on tanning, usage, and climate. An alligator strap with vegetable tanning lasts 3–5 years with moderate daily use; exposure to constant humidity or prolonged perspiration reduces this to 18–24 months. Shell cordovan, inherently more robust, reaches 5–8 years. Calf with vegetable tanning spans 2–4 years. Accelerating factors: seawater, tropical climates, lack of maintenance (cleaning and drying). Vegetable-tanned leather ages naturally with patina; superior vegetable-tanned leather improves over the years.
