Chopard
L.U.C 161977-5001— lug 20mm

The lug width of the Chopard L.U.C 161977-5001 is 20 millimetres. This measurement represents the distance between the two lugs of the case and is essential for selecting a compatible strap. For verification, use a digital calliper positioned perpendicularly between the lugs.

For the 161977-5001 in rose gold, alligator straps with vegetable tanning (chocolate brown or black) represent the most elegant and sophisticated choice. Alternatively, premium calf leather in cognac or bordeaux creates a material contrast that reinforces the aesthetic value of rose gold. Rubber or slate-grey NATO straps are ideal for sporting applications.

For the 161977-5001 model, strap replacement is achieved by removing the spring bars from the lugs. Proceed with caution using a dedicated tool (pin remover) to avoid damaging the strap and lugs. Ensure that the new strap has a 20mm lug width and that the spring bars are firmly inserted in both positions.

Yes, any strap with a 20mm lug width is compatible with the 161977-5001, provided the attachment spring bars are correctly dimensioned. Bespoke artisanal straps offer superior aesthetic advantages over standard versions: choice of materials, personalised stitching thread and ergonomic conformation tailored to the individual wrist.

The lifespan of a leather strap depends on the tanning type, quality of the leather and frequency of use. An alligator strap with vegetable tanning has an average lifespan of 8–12 years with daily use and periodic maintenance. Premium calf lasts 6–10 years. Periodic replacement is advisable to preserve the aesthetic of the timepiece and prevent structural wear that could damage the lugs.
