Strap for Artelier Skeleton 40.5 Diamonds

The lug width of the Oris Artelier 01 734 7670 4019-07 5 21 70FC is 21 millimetres. This measurement represents the internal distance between the metal lugs on the case and determines which strap is compatible with the watch. It is important to measure it with a digital calliper on the case to ensure correct strap attachment.

For the Artelier model 01 734 7670 4019-07 5 21 70FC we recommend a vegetable-tanned alligator strap to enhance the formal skeleton character, or a NATO strap in high-tenacity nylon for a sportier interpretation. The choice depends on usage: formal-evening for alligator, everyday-versatile for NATO. The compatible 21mm range is available in leather, rubber and fabric.

To change the strap on a 21mm lug-width watch: 1) Use a spring bar remover or professional tool to extract the closure pins positioned perpendicular to the lugs; 2) Insert the new strap into the case slots, ensuring the terminal ends fit securely; 3) Reinsert the locking pins and verify there is no lateral movement. This operation should be performed on a soft surface (felt mat) to protect the case.

Yes, there are quality-certified aftermarket straps compatible with the Oris Artelier with 21mm lugs. Milano Straps offers a specialised range of 21mm straps in leather, NATO and rubber, selected according to high quality standards. Compatibility is guaranteed by the standardised lug width. It is advisable to always verify technical specifications (lug width, thickness) before purchase to ensure perfect mechanical fitment.

The lifespan of a leather strap depends on the material and usage: an alligator strap with vegetable tanning maintains structural functionality for 5-7 years of moderate daily use, developing natural patina over time. Smooth calf leather has similar longevity (4-6 years). Degradation factors: prolonged direct moisture exposure, saline sweat, intense UV rays. Regular maintenance (periodic cleaning, annual water-repellent treatment) significantly extends the useful life of the strap.
