Strap for L.U.C XPS Rose Gold / 4 Arabics

The lug width of the Chopard L.U.C 161920-5001 is 19 mm. This measurement should be verified using a digital calliper positioned perpendicularly between the two lugs. A compatible strap must respect a tolerance of ±0.1 mm to ensure a fit free from lateral play and proper strap-changing functionality.

For a rose gold Chopard L.U.C, dark brown or mahogany alligator is the most harmonious choice: the geometric grain creates visual continuity with the case's satin finish. Alternatively, a high-quality vegetable-tanned calf strap develops an evolving patina over time. Avoid highly saturated colours that contrast with the understated character of rose gold.

Use a dedicated spring bar removal tool whilst keeping the watch stable. Insert the small hook under the spiral spring of the upper lug, applying gentle upward pressure until it releases. Repeat for the lower lug. The new 19 mm strap is installed by threading the spring first, ensuring it seats correctly on both sides.

Yes, provided the strap is manufactured to a tolerance of ±0.1 mm on the 19 mm width and the lugs are dimensioned to eliminate lateral play on the case. Artisanal straps from milanostraps.it, in alligator or calf, meet these standards and are fully compatible with the 161920-5001.

A premium vegetable-tanned leather strap, subject to moderate daily use (3–5 days per week), maintains structural and aesthetic integrity for 2–3 years. Alligator is more durable than calf; calf develops patina more rapidly but remains functional beyond 3 years. Exposure to humidity and direct sunlight accelerates ageing. Straps from milanostraps.it include an 18-month warranty and can be serviced at the Casati Milano atelier.
