Strap for Quai des Bergues N°27 bis

The lug width of the Czapek Quai des Bergues QDB27bis is 20 mm. This dimension is determined by the distance between the spring bar pins of the lugs, measured centre-to-centre in a position perpendicular to the dial. This specific measurement reflects the proportional equilibrium between the 42.5 mm case diameter and the overall geometry of the model.

There is no absolute 'best', but contextual choices: alligator with natural tanning represents the aesthetic and formal zenith, creating luminous contrast with the titanium case; calf leather with vegetable tanning develops amber patina over time and dialogues warmly with the case geometry; NATO fabric in reinforced canvas offers daily practicality without visual competition; technical rubber polymer emerges as a modern choice resistant to intensive wear.

The procedure requires a specific tool (spring bar tool) and precision: insert the flat lever between the lug and the pin, gently pushing to release the spring-loaded terminal. Once one side is freed, extract the pin and repeat on the opposite side. Install the new strap following the reverse process, ensuring the pin is completely inserted and the spring properly positioned. Avoid abrupt movements that could scratch the titanium lugs.

Yes, provided the lug width is accurately 20 mm and the pins are correctly inserted. However, always verify the construction quality of aftermarket straps: poorly toleranced pins, incorrect curves, or substandard finishing can compromise both aesthetics and functionality. Straps from specialised artisanal manufacturers guarantee finishing proportionate to the case's excellence.

Durability depends on usage intensity and leather quality: an alligator or shell cordovan strap with vegetable tanning resists approximately 3-5 years of moderate daily wear, developing natural patina over time; calf leather achieves 2-4 years; nocturnal wear and perspiration exposure accelerate deterioration. Periodic maintenance—cleaning with a damp cloth, conditioning with specific balms—significantly extends longevity. Rubber or NATO straps offer superior resistance, lasting 7-10 years with appropriate care.
