Strap for Quai des Bergues N°23

The Czapek Quai des Bergues QDB23 features a lug width of 20 millimetres. This measurement represents the distance between the lugs that attach the strap to the case. To verify compatibility with an aftermarket strap, measure this width with a digital calliper: it must be exactly 20mm to ensure a perfect fit without any play or movement.

The ideal strap depends on intended use. An alligator strap with vegetable tanning and steel deployant clasp represents the most coherent choice with Genevan haute horlogerie identity, creating aesthetic dialogue with the brushed case. Vegetable-tanned box calf offers smooth elegance and develops patina over time. For dynamic contexts, a cotton-silk NATO or Fluorosilicone rubber maintains stylistic dignity with versatility. Milano Straps offers all these options in 20mm measurement.

Strap replacement requires extraction of the spring bars connecting the strap to the case lugs. Use a dedicated spring bar tool to compress the bar and slide the strap out of the lugs. Verify that the new strap has exactly 20mm lug width. Reinsert the spring bars into the new strap, ensuring they seat completely in their housings. The operation requires only calibrated pressure, not hammering or impact tools.

Yes. Any strap with 20mm lug width is compatible with the Czapek Quai des Bergues QDB23. Milano Straps offers a specialised collection of 20mm straps in alligator, calf, shell cordovan, NATO and rubber, all ready for shipment and customisable according to colour and construction preferences. Compatibility is guaranteed by matching lug width.

Longevity depends on material and usage. An alligator or shell cordovan strap with vegetable tanning, used daily, typically lasts 5-7 years before requiring replacement due to natural wear. Vegetable-tanned calf has a slightly shorter cycle, approximately 4-6 years. Vegetable tanning permits replacement of the clasp pin (deployant) without discarding the entire strap, extending useful life. Extreme humidity conditions accelerate wear; proper storage (away from heat sources) extends it significantly.
