Strap for Da Vinci Perpetual Red Gold / White / English / Bracelet

The lug width of the IWC Da Vinci IW9252-13 is 19mm. This measurement represents the distance between the inner spring bar pins of the case and determines compatibility with aftermarket straps. Always verify the measurement with a digital calliper before purchasing a replacement strap.

For the Da Vinci IW9252-13 in 18-carat rose gold, we recommend alligator leather in dark brown or black tones, which naturally complements the warm hue of the case. Shell cordovan in bordeaux offers a refined balance between luxury and natural patina development. For formal contexts, vegetable-tanned calf leather guarantees elegance and sustainability.

Changing the strap on the Da Vinci IW9252-13 requires specific tools: a spring bar tool to extract the suspension pins, a soft surface to avoid case scratching, and attention to the 19mm pin diameter. We recommend entrusting the operation to a professional, or contacting Casati Milano for a guaranteed strap-change service.

Yes, the IW9252-13 is compatible with quality aftermarket straps provided they are constructed with a 19mm lug width. The straps available on milanostraps.it are specifically manufactured for this dimension, customisable in material, colour, size and details. The 18-month warranty covers artisanal straps created by Casati Milano.

The lifespan of a leather strap depends on the material, frequency of use and maintenance. Alligator and shell cordovan maintain structural integrity for 3-5 years with daily use; vegetable-tanned calf leather has similar longevity but evolves aesthetically more rapidly. Regular maintenance—cleaning and protection from excessive humidity—significantly extends strap lifespan.
