Chopard
L.U.C 161902-5055— lug 19mm

The lug width of the Chopard L.U.C 161902-5055 is 19 mm. This measurement is not a commercial standard size and requires careful strap selection to ensure perfect fit between the case and strap, without lateral movement.

For a skeletonised white gold watch such as the 161902-5055, an alligator strap with vegetable tanning or high-quality calf leather is recommended. Dark brown alligator enhances the luminosity of gold and the visibility of the movement; blue or cognac calf provides versatility whilst maintaining formal elegance.

The strap is changed using a specific tool (spring bar tool or small screwdriver) to remove the spring bars from the case lugs. Position the bar on the internal spring, press slightly, and slide out. Insert the new strap, aligning the holes with the lugs, and snap the bars into place. Avoid forcing to prevent damage to the gold lugs.

Any strap with a 19 mm lug width is compatible. However, to preserve the aesthetic identity and quality of the piece, artisanal high-end leather or rubber straps are recommended, avoiding synthetic materials of poor quality or colours inconsistent with white gold.

Durability depends on material and usage. A high-quality alligator or calf strap with vegetable tanning lasts 3 to 5 years with moderate daily wear. Natural ageing adds patina and character. Frequent exposure to water, sweat, and UV rays reduces lifespan. Standard warranty is 18 months.
