Strap for Oris Divers 01 643 7609 8585

The Oris Divers 01 643 7609 8585 features a 24-millimetre lug width. This measurement is specific to this model and represents the ideal ratio between the case diameter (47 mm) and the overall aesthetic proportion. When selecting an aftermarket strap, it is essential to verify that the internal passage of the spring bar housing accommodates 24 millimetres precisely without lateral play.

The choice depends on use and context. For formal environments and office wear, we recommend a genuine Niloticus alligator strap or vegetable-tanned calf leather, both of which develop natural patina over time. For aquatic activities and gym use, an FKM rubber or neoprene strap ensures complete water resistance and rapid drying. A black NATO strap maintains the authentic sporting vocation of the toolwatch. All 24mm straps in our collection have been tested for compatibility and comfort on this case.

Strap replacement requires minimal tools: a Swiss Army knife, a light mist of water or silicone-based lubricant, and a clean work surface. Position the watch with the lugs facing upward, lightly dampen the inner passage of the old strap to facilitate extraction, and gently push the spring bar using the knife's lever. Extract the bar completely, remove the old strap, insert the bar into the new 24mm strap, and reinsert into the case lugs. Ensure the bar is fully seated on both sides.

An aftermarket strap is compatible if it features a 24-millimetre lug width. Milano Straps offers a comprehensive collection of straps for this measurement, manufactured in Italy by specialised artisans. Each strap has been verified for compatibility with this specific model. Should you require customisations (length, buckle type, material), contact our team: Casati Milano, the bespoke atelier by appointment, can create tailored solutions.

Leather strap longevity depends on usage and maintenance. A quality vegetable-tanned calf strap, worn daily, maintains structural integrity for 2–4 years, developing aesthetic patina characteristic of natural leather. Alligator, due to its dense fibrous structure, may last 4–6 years with equivalent use. Longevity increases significantly if the strap is dried after humidity exposure and protected from direct heat. Rubber or NATO straps offer superior durability (5–8 years), as they are not subject to biological stress.
