Chopard
L.U.C 161920-5002— lug 20mm

The lug width of the Chopard L.U.C 161920-5002 is exactly 20 millimetres. This dimension represents the distance between the two attachment pins on the case, and it is critical for ensuring compatibility with any aftermarket strap. Always verify this measurement with a ruler placed in the attachment slot before ordering a replacement strap.

For the 161920-5002 in rose gold, an alligator strap with fine grain in tobacco or brown tones is recommended, as it respects the dress watch elegance of the timepiece. Shell cordovan is the noblest alternative for those seeking deep patina development. Vegetable-tanned calf leather offers a more contemporary option, whilst a black alligator strap is virtually mandatory for formal evening occasions.

To change the strap, obtain a quality spring bar remover tool. Place the watch on a soft surface, insert the tool into the lug slot from below, gently lift the elastic pin, and slide the old strap away. Repeat on the other side. Insert the new strap ensuring the pins are aligned before fully compressing. A lug width of 20 millimetres leaves no room for error: the pin must enter its seat with natural fluidity.

Yes, provided the strap has been constructed for a lug width of exactly 20 millimetres. Always verify that the manufacturer specifies this dimension. An 18 or 22 millimetre strap will not be compatible. Artisanal straps produced for this dimension guarantee complete compatibility with the 161920-5002 without requiring any modifications.

A high-quality alligator, cordovan, or calf leather strap typically lasts 3 to 5 years with daily wear, depending on exposure to perspiration, moisture, and UV radiation. The rose gold of the 161920-5002 never enters water given its dress watch usage, so the strap will age uniformly. An 18-month guarantee from the manufacturer covers construction defects; replacement for natural wear depends upon personal habits.
