Frequently asked questions

What is the lug width of the Chopard L.U.C 161927-5001?

The lug width of the Chopard L.U.C 161927-5001 is 18mm. This measurement is taken between the inner holes of the lugs and is essential for selecting a compatible strap. You can verify it using a calliper or ruler.

Which strap is most suitable for the Chopard L.U.C 161927-5001?

For the 161927-5001 in rose gold, we recommend a high-quality alligator in warm cognac tone, or a shell cordovan in bordeaux for a patina that ages beautifully. A vegetable-tanned calf leather is ideal for daily wear, whilst a black rubber strap offers sporty versatility.

How do I change the strap on my Chopard L.U.C 161927-5001?

Strap replacement is performed by removing the spring bars from the lugs using a dedicated tool (spring bar tool). Extract the pin, detach the old strap and insert the new one, ensuring the pin clicks correctly into both seats. If you are inexperienced, consult a watchmaker.
