Strap for Quai des Bergues N°21

The lug width of the Czapek Quai des Bergues QDB21 is precisely 20mm, measured internally between the pin anchors. This dimension ensures universal compatibility with all 20mm artisanal straps. Correct measurement must be performed perpendicular to the pins, excluding the outer thickness of the lugs. A tolerance of ±0.2mm is acceptable for smooth strap insertion.

For the Czapek Quai des Bergues QDB21, we recommend genuine alligator straps for formal contexts, shell cordovan for timeless elegance, or vegetable-tanned calf leather for those preferring organic warmth. For sports applications, ballistic canvas NATO straps or premium vulcanised rubber variants provide versatility whilst maintaining visual refinement.

Strap replacement requires a spring bar tool to compress the pins at both ends. Position the watch with the lug facing upward, insert the tool into the pin's access hole, apply gentle downward pressure to release the pin from the old strap, and remove the strap. Repeat from the opposite side. To install the new strap, guide the pins into the eyelet slots, ensuring perfect centring before releasing the compression.

Yes, the Czapek Quai des Bergues QDB21 with 20mm lug width is universally compatible with any 20mm artisanal strap in our catalogue. There are no proprietary attachment variants: standardised lug width guarantees complete interchangeability between different models and brands, allowing you to personalise your watch according to seasonal and stylistic preferences.

A high-quality artisanal leather strap (alligator, shell cordovan, vegetable-tanned calf) guarantees a lifespan of 3–5 years with daily wear, depending on maintenance and weather exposure. Vegetable tannage develops natural patina over time, enhancing aesthetics. Premium vulcanised rubber straps last 5–7 years without visible degradation. Periodic maintenance with specialised creams significantly extends longevity.
