Strap for Kleine Da Vinci Stainless Steel / White / Black Croco

The lug width is 15 millimetres. This measurement is specific to the women's models in the IWC Da Vinci collection and represents the critical specification for selecting any compatible aftermarket strap.

Alligator is the primary choice, as the minimalist elegance of the watch demands a natural texture and patina that evolves over time. Alternatively, vegetable-tanned calf leather offers structure and durability, whilst shell cordovan provides natural water resistance and superior aesthetic ageing.

The strap is replaced via spring bars—small metal pins that connect the strap to the case lugs. Using a spring bar tool, you compress the pin to separate the strap from the case, then insert the new one. This operation requires care, especially with a 29mm case where manoeuvrability is limited.

Yes, any strap with a 15mm lug width is compatible with the IW3736-05. The aftermarket offers options in alligator, calf leather, shell cordovan, and technical fabrics. We recommend verifying strap thickness to ensure it fits perfectly into the case slots without movement.

Durability depends on usage and leather quality. A quality alligator or calf, worn daily, maintains structural integrity for 3–5 years. Factors such as body moisture, perspiration, sun exposure, and wearing frequency influence this estimate. Aesthetic ageing begins earlier: patina develops within 2–3 months of regular wear.
