Strap for L.U.C XPS Fairmined

The lug width of the Chopard L.U.C 161920-5006 is 18mm. This measurement represents the distance between the two attachment points on the case where the strap is fixed, and it is fundamental to constructive compatibility. On a watch with a 39.50mm diameter case, the 18mm lug width represents the ideal proportion according to Chopard's design principles.

For the rose gold Chopard L.U.C 161920-5006, we recommend an alligator strap in cognac with natural back, or a black shell cordovan. Both materials maintain aesthetic coherence with Swiss watchmaking construction: alligator amplifies rose gold through soft tonal contrast, whilst shell cordovan introduces refined chromatic verticality. A rose gold deployant clasp completes the strap functionally.

Strap change requires a quality spring bar tool. Insert the small flat blade of the tool between the case lug and the strap end, applying gentle vertical pressure to release the bayonet spring. Extract the spring bar from the case, remove the old strap and insert the new one by aligning the attachment holes. Reinsert the spring bar until it clicks into position. We recommend having this operation performed at an authorised service centre to avoid damage to the rose gold case.

The Chopard OEM (Original Equipment Manufacturer) strap is manufactured to proprietary specifications and typically comes with warranty. Artisanal aftermarket straps, such as those from Milano Straps, offer flexibility in material selection, custom sizing and access to noble leathers that are sometimes unavailable in official catalogues. Both approaches are legitimate: the choice depends on the owner's aesthetic priorities. The important factor is verifying exact lug width compatibility (18mm) and the quality of stitching construction.

Durability depends on frequency of wear, environmental conditions (humidity, sun exposure) and leather quality. An alligator or shell cordovan strap with excellent tanning maintains structural integrity between 3 and 5 years of daily wear. Vegetable tanned leather ages aesthetically in a positive manner, developing patina, whilst retaining mechanical resistance for similar periods. Milano Straps offers an 18-month warranty on artisanal straps, covering manufacturing defects and premature stitch failure.
