Chopard
L.U.C 171948-5001— lug 20mm

The lug width of the Chopard L.U.C 171948-5001 is 20mm. This is the internal distance between the lugs where the strap is inserted. Measured with a digital calliper on the inner lug shoulders, it ensures correct aesthetic proportion against the 40mm case. The maximum thickness supported is approximately 4.5-5mm to preserve the minimal case aesthetics.

Alligator in dark brown or burgundy represents the classic and versatile choice for the 171948-5001. Natural shell cordovan is recommended for those desiring progressive patina development over time. Vegetable-tanned calf is ideal for sustainable daily wear. For formal contexts, polished black alligator is always appropriate. Rubber is not recommended to preserve the reference's elegance.

To change the strap, you require a quality spring bar tool. Position the watch face-up, identify the small hole on the lug spring, insert the tool to compress the spring, and extract the metal pin. Repeat on the opposite side. Insert the new strap by aligning the pin with the hole and release the spring. We recommend having this operation performed by a qualified centre to avoid scratching the rose gold case.

Yes, provided it is 20mm in width and manufactured from quality materials (alligator, shell cordovan, vegetable-tanned calf). It is essential to verify that thickness does not exceed 4.5-5mm to avoid compromising case aesthetics. Customisable straps from Milano Straps, handcrafted, are fully compatible with the 171948-5001 and maintain reference quality standards.

A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) typically lasts 3-5 years with regular wear, depending on exposure to moisture, perspiration, and sunlight. Shell cordovan, if properly maintained, can last longer whilst developing a compelling patina. It is advisable to rotate straps to distribute wear. Milano Straps offers an 18-month warranty on straps personalised by the Casati Milano atelier.
