Frequently asked questions

What is the lug width of the Pequignet Rue Royale 9010543CN?

The Pequignet Rue Royale 9010543CN features an 18mm lug width, the standard collection width established by Pequignet for this line. This measurement is calculated from the internal distance between the lug shoulders and is compatible with the vast majority of quality aftermarket straps.

Which strap is most suitable for the Pequignet Rue Royale 9010543CN?

For this model, we recommend straps in vegetable-tanned alligator leather (medium brown or cognac) or vegetable-tanned calf. These materials reflect the sophisticated and understated aesthetic of the stainless steel case. For casual wear, a dark grey or black NATO strap represents a contemporary choice without stylistic compromise.

How do you change the strap on the Pequignet Rue Royale 9010543CN?

The strap is changed by removing the spring bars (lugs attachment pins) from the case using a small hammer and a spring bar removal tool. The 18mm spring bars on the Rue Royale require gentle pressure to extract from the lugs; it is recommended to work on a clean cloth to avoid accidental loss of small components.

Can I use an aftermarket strap on this reference?

Yes, the Pequignet Rue Royale 9010543CN accepts aftermarket 18mm straps from any manufacturer, provided they are constructed to professional standards. We recommend manually verifying the strap's fit into the case lugs before final purchase, to exclude minor manufacturing variations between producers.

How long does a leather strap last on this watch?

A quality leather strap (alligator or vegetable-tanned calf) on a daily-wear wristwatch like the Rue Royale typically lasts 4-6 years before requiring replacement. Wear accelerates in humid climates or with prolonged exposure to perspiration. Vegetable-tanned leather develops a natural patina that enhances aesthetics over time, but the fibre structure thins after three years of intensive use.
