Chopard
L.U.C 161920-1005— lug 20mm

The lug width of the Chopard L.U.C 161920-1005 is 20mm. This measurement represents the distance between the two spring bar attachment points where the strap connects to the case. This dimension is fixed for this model and is essential when ordering compatible straps.

The best strap depends on intended use: for formal occasions, alligator with vegetable tanning enhances the minimalist elegance of the dial. For daily wear, French Taurillon calf offers comfort and durability. For versatility, cordovan develops a fascinating patina over time. The choice should respect the sober proportions of the L.U.C collection.

To change the strap, position the watch on a soft cushion with the case facing down. Using a spring bar tool, gently push the pin inward to release the upper lug attachment, then repeat for the lower attachment. Insert the new 20mm strap into the lugs until you feel the locking pin click into place. Since the case is white gold, avoid accidental impacts during the operation.

Any strap with a 20mm lug width is compatible, provided it features robust spring bars suited to white gold. Quality must be coherent with the watch's identity: synthetic or low-grade straps are inadvisable. Specialist suppliers like milanostraps.it offer curated selections, customisable in length, initials and stitching thread.

Lifespan depends on leather quality and usage conditions. Alligator or cordovan with vegetable tanning lasts 8–12 years with regular maintenance (occasional cleaning, drying after moisture exposure). Mid-range calf resists 3–5 years. Perspiration, sunlight exposure and humidity shorten strap life. A bespoke strap from Casati Milano benefits from an 18-month guarantee against manufacturing defects.
