Strap for Quai des Bergues Lady N°9

The lug width (width between the lugs) of the Czapek Quai des Bergues QDB9 is 20 millimetres. This measurement corresponds to the vertical distance between the case attachment holes and determines compatibility with straps and bracelets. Measuring accurately requires placing a ruler perpendicular across the two holes on the case.

For the QDB9 in 18-carat red gold, an alligator or shell cordovan strap represents the ideal choices. Alligator offers pure elegance with subtle natural grain, whilst shell cordovan ensures compactness and evolving patina that harmonises with ageing red gold. Versatile alternatives include vegetable-tanned calf leather in cognac brown or slate grey tones.

The QDB9 strap connects to the case via screw-secured or pressure-fitted lugs, depending on construction. Using a spring bar tool, position the flat lever into the lateral hole of the lug to compress the internal spring, then extract the old strap. The new 20mm strap is inserted by aligning the lateral holes with the pins and releasing the spring mechanism. Professional removal is recommended through an authorised service centre.

Yes, any strap featuring a 20-millimetre lug width is compatible with the QDB9, provided it features standard attachment fittings. High-quality aftermarket straps, including vegetable-tanned leather, alligator or technical rubber options, offer complete compatibility. We recommend verifying the total strap length to ensure comfort on your specific wrist.

A high-quality leather strap (alligator, shell cordovan or vegetable-tanned calf) typically lasts 3-5 years with regular daily use, depending on moisture exposure, temperature and mechanical stress. Shell cordovan, being more compact in fibre structure, tends to last longer. Regular maintenance (gentle cleaning, natural air-drying) and seasonal rotation with alternative straps significantly extend useful lifespan.
