FAQ

What is the lug width of the Chopard L.U.C 161980-5001?

The lug width of the Chopard L.U.C 161980-5001 is precisely 19.00 millimetres. This measurement is exceptionally rare in the aftermarket strap market and requires specialist suppliers such as milanostraps.it. To verify compatibility, measure the distance between the inner edges of the two lugs (anses) that connect the case to the strap.

Which strap material is recommended for the Chopard L.U.C 161980-5001?

African alligator leather in black tones remains the most recommended choice: its fine grain does not compete with the visible skeleton movement. Shell cordovan with vegetable tanning introduces chromatic elegance in aged burgundy. Calf leather with hammered grain in brown represents a versatile compromise. Avoid rubber and synthetic materials: they do not reflect the sophisticated constructive philosophy of a skeletonised timepiece.

How do I change the strap on the Chopard L.U.C 161980-5001?

Position the watch on a soft cushion to protect the case. Locate the spring bars (ressorts) behind the strap: these are small metal cylinders that hold the strap to the lugs. Using a dedicated tool (often included with replacement straps) or a blunt knife, gently press the bar towards the centre, pushing the outer pin outward to extract the strap end. Repeat on the other side. Ensure the bars remain in their original seated position before inserting the new strap.

Is the Chopard L.U.C 161980-5001 compatible with generic 19mm aftermarket straps?

Yes, provided they are authentically 19.00 millimetres. Many manufacturers claim 19mm but supply 18.5mm or 19.5mm. At milanostraps.it, every strap is measured with zero tolerance. Always verify the return policy before purchase and request confirmation of exact measurement before dispatch. The fit of spring bars may additionally vary: some straps may require replacement of the original bars.

How long does a leather strap last on a watch like the Chopard L.U.C 161980-5001?

A high-quality leather strap (alligator, shell cordovan, vegetable-tanned calf) lasts between 3 and 5 years with moderate daily wear. Durability depends on exposure to perspiration, water and natural leather oxidation. Alligator is more resistant than calf. A vegetable-tanned strap develops natural patina over time, increasing aesthetic character. At milanostraps.it and the Casati Milano atelier, it is possible to request replacement of a worn strap with a new one whilst maintaining the same lug width.
