Chopard
L.U.C 161932-9002— lug 20mm

The Chopard L.U.C 161932-9002 features a 20mm lug width. This measurement is standard for the 39.50mm case diameter and ensures smooth strap passage through the spring bars without mechanical play. Always verify the lug width manually with a caliper perpendicular to the spring bars before purchasing an aftermarket strap.

For a L.U.C 161932-9002 in platinum, we recommend fine alligator in black or chocolate brown tones, as the grain texture harmonizes with the satin finish of the case. Smooth calfskin is ideal for daily wear with less sensitivity to surface scratches. Avoid rubber and NATO: their utilitarian aesthetic conflicts with the formal nature of the L.U.C movement.

Remove the previous strap: locate the metal spring bars at the ends of the lugs, then use a spring bar tool to compress the spring-loaded pin, releasing the strap. Insert the new strap by aligning the holes at the lug ends, and the pin will snap into position. Verify that the strap is perfectly centered before wearing the watch.

Yes, any strap with a 20mm lug width is mechanically compatible. However, aesthetics must be considered: the L.U.C requires high-quality straps (alligator, vegetable-tanned calfskin) to preserve the elegance of the platinum case. The customizable artisanal straps from Milano Straps ensure aesthetic harmony and durability.

A quality leather strap (alligator or vegetable-tanned calfskin) lasts an average of 3–5 years with daily use, extending to 7–10 years with occasional use. Longevity depends on exposure to moisture, perspiration, and UV rays. Milano Straps includes an 18-month warranty and can be restored at the Casati Milano atelier to extend operational life.
