Strap for L.U.C Quattro Rose Gold / Diamond

The lug width of the Chopard L.U.C 171926-5001 is 20 millimetres. This dimension is measured by placing a ruler directly between the spring bars (the metal pins that attach the strap to the case) without touching the case itself. A strap with incorrect lug width will not fit the lugs and may damage the spring bars during installation.

For the Chopard L.U.C 171926-5001 in rose gold, the following straps are recommended: alligator in dark brown to amplify formal luxury, shell cordovan in burgundy for evolving patina, vegetable-tanned calf leather for natural authenticity, and dark blue NATO for daily versatility. The choice depends on intended use and desired aesthetic context.

To change the strap on the 171926-5001, remove the spring bars from the lugs using a specialised tool (spring bar tool or dedicated lever). Position the watch on a soft surface, insert the tip of the tool into the small lateral hole in the spring bar, gently lift and the bar will release from the lug. Repeat for both sides, then insert the spring bars into the new 20mm strap.

The 20mm strap is compatible with any watch that features the same 20 millimetre lug width. However, different models may have lugs with different thicknesses or curvatures: before installing a strap designed for the 171926-5001 on another timepiece, always verify the actual geometric compatibility of the lug with the case.

A quality leather strap (alligator, shell cordovan or calf) typically lasts between 3 and 7 years with regular use, depending on climate conditions, humidity, sun exposure and care. Vegetable tanning tends to age better, developing patina. To extend durability, avoid prolonged contact with water, excessive perspiration and chemical solvents, and periodically apply a protective balm specifically designed for leather.
