Chopard
L.U.C 161948-1001— lug 20mm

The Chopard L.U.C 161948-1001 features a lug width of 20 millimetres. This is the distance between the two lugs where the strap is attached to the case. Accurate measurement is essential for strap compatibility, as 19mm lugs would be too tight and 21mm lugs would create unacceptable lateral play on a timepiece of this quality in 18-carat white gold.

Nile alligator is the most coherent choice with the white gold identity of the case. The peau natural texture of the leather reflects light with subtle nuances that echo the metallic lustre of the metal. For versatility and historical value, honey or cognac alligator develop golden patina over time. For those who appreciate tradition, shell cordovan offers natural brilliance and legendary durability. Vegetable-tanned calf represents an elegant alternative that develops character with daily wear.

Strap changing requires specific tools: a spring bar tool to delicately remove the spring bar that supports the strap in the case lugs. Position yourself in a well-lit area, insert the tool into the small hole below the spring bar, lift gently to free the bar from the lug pocket, then extract the strap. Repeat from the opposite side. For inserting the new strap, align the metal horns with the lugs, compress the spring bar slightly until it locks into position. Given the precious nature of 18-carat white gold, it is advisable to have a professional assist you to avoid scratches on the case and lugs.

Yes, provided the strap is compatible with the 20mm lug width and standard spring bars. Milano Straps offers handcrafted straps online customisable in noble leathers (alligator, calf, shell cordovan) certified for the Chopard L.U.C 161948-1001. It is essential to select a strap from a specialised manufacturer who understands the quality standards required by a high-end timepiece. The 18-month warranty offered by Casati Milano on bespoke straps protects your investment.

The lifespan of a leather strap depends on the material and intensity of use. A strap in Nile alligator or shell cordovan, with traditional tanning, will resist 3–5 years with moderate daily wear, developing noble patina over time. A vegetable-tanned calf has a similar lifespan. Determining factors include exposure to moisture, perspiration and sunlight. A technical NATO in synthetic material offers superior durability. Milano Straps supplies straps that age elegantly; Casati Milano's 18-month warranty covers manufacturing defects, not natural leather wear.
