Chopard
L.U.C 161963-9001— lug 20mm

The lug width of the Chopard L.U.C 161963-9001 is 20mm. This measurement represents the horizontal distance between the two spring bars that connect the case to the strap. Any compatible strap must feature a 20mm internal slot (lug hole) to ensure secure attachment without lateral play.

For the 161963-9001 in platinum, dark brown or black alligator is the classical choice, emphasising contrast with the case. Alligator crocodile provides tactile comfort and a more intimate feel. Vegetable-tanned leather allows the hide to develop a natural patina over time. For contemporary elegance, shell cordovan creates an intrinsic lustre that dialogues beautifully with the platinum.

Strap replacement is accomplished by extracting the spring bars from their housings within the case. Using a dedicated tool (spring bar tool), apply gentle pressure to the small button on the spring bar to compress the internal spring, allowing the pin to slide out of the slot. Once extracted, the previous strap releases and the new one can be installed by reversing the procedure. Operate with care to avoid scratching the case.

Yes, any strap with a 20mm lug width is compatible with the 161963-9001. Artisanal straps from Milano Straps offer customisation in leather, materials and finishes, maintaining quality standards appropriate to a timepiece of this calibre. Alternatively, Casati Milano creates bespoke straps with personal consultation and 18-month warranty.

Longevity depends on material and usage patterns. High-quality alligator, worn daily, maintains structural integrity for 5-7 years. Calf crocodile requires more frequent maintenance (conditioning every 6-12 months) and typically lasts 3-5 years. Vegetable-tanned leather ages gracefully, improving aesthetically over time, with potential lifespan exceeding 7 years if conditioned regularly. Shell cordovan, extremely dense, can exceed 10 years of useful life.
