Chopard
L.U.C 161926-9001— lug 20mm

The lug width of the Chopard L.U.C 161926-9001 is 20mm. This measurement represents the internal distance between the vertical lugs where the strap is inserted. To verify it, measure with a digital calliper the width of the suspension parallel to the dial, with the case unattached to any strap.

For the L.U.C 161926-9001, we recommend straps in Louisiana or Mississippi alligator leather, which preserve the aesthetic nobility of white gold or platinum. Alternatively, vegetable-tanned calf leather with natural patina ensures elegant ageing. We advise against rubber and technical fabrics, as they would contradict the formal identity of the model.

To change the strap, remove the spring bars using a dedicated tool, pushing upward from below to free the bar from one side. Insert the spring bars into the lugs of the new strap and ensure they are locked symmetrically. If your watch features a deployant clasp, it is advisable to have the operation performed by an authorised service centre.

Yes, 20mm aftermarket straps are fully compatible with the 161926-9001. However, verify that the strap has been manufactured according to Chopard standards (construction quality, stainless steel or gold spring bars, thickness consistent with the case). Milanostraps offers straps certified for this size with 18-month warranty.

A high-quality leather strap (alligator, calf, cordovan) lasts approximately 3–5 years with daily wear, depending on climatic conditions and humidity. Vegetable-tanned straps tend to develop patina and age elegantly, extending the perception of durability. Casati Milano offers an 18-month warranty and leather regeneration services.
