The L.U.C 161978-5001, seen from the bench

The Chopard L.U.C 161978-5001 is a 40mm white gold 18k timepiece featuring the caliber L.U.C 96.24-L with tourbillon escapement, COSC chronometer certification, and 72-hour power reserve.

Frequently asked questions

What is the exact lug width of the Chopard L.U.C 161978-5001?

The lug width of the Chopard L.U.C 161978-5001 is precisely 18mm, measured between the inner edges of the case lugs. This dimension is critical for proper strap compatibility and to ensure correct fitment without excessive play or installation difficulties.

What type of strap is recommended for the Chopard L.U.C 161978-5001?

For the Chopard L.U.C 161978-5001 in white gold, we recommend African alligator in deep tones (chocolate brown, slate grey), Horween shell cordovan, or vegetable-tanned calf leather. Alligator represents the formal choice for this precious case, creating elegant material contrast with the white gold finish.

How should I correctly change the strap on my Chopard L.U.C 161978-5001?

Remove the case lugs carefully using an appropriate tool. Slide the old strap out, verify that the lugs are undamaged, insert your new 18mm-compatible strap through the lug holes, then carefully reinsert the lugs without creating stress on the gold case.

Is an aftermarket strap compatible with the Chopard L.U.C 161978-5001?

Yes, any strap with an 18mm lug width is compatible. However, to preserve the watch's value and aesthetics, we recommend straps in noble materials such as alligator, shell cordovan, or vegetable-tanned leather, ensuring that the lug holes are gold-finished for consistency with the case.

How long does a leather strap last on the Chopard L.U.C 161978-5001?

Durability depends on daily wear and proper storage. A high-quality alligator or cordovan strap typically lasts 4-6 years with regular maintenance. Vegetable-tanned leather, when worn daily, develops a natural patina and may require reconditioning after 3-4 years of regular use.
