Strap for Da Vinci SL Stainless Steel / Black

The IWC Da Vinci IW3528-05 features a lug width of 19 millimetres. This measurement, taken between the inner terminals of the case, is specific to this model and emphasises the harmonious proportions of the 37-millimetre case. An aftermarket strap must respect this measurement precisely to ensure a perfect fit.

For the Da Vinci, we recommend noble materials that do not compete with the linear aesthetic of the case. Nile alligator in cognac brown is the most advisable classical choice. Alternatively, vegetable-tanned calf leather offers a fascinating natural patina, whilst shell cordovan provides an almost metallic structure. All these materials, with proper construction care, guarantee aesthetic longevity spanning years.

Changing the strap requires a specific tool: a spring bar tool (or extractor). Position yourself facing the dial and locate the metal pins (spring bars) that connect the strap to the case lugs. Press gently towards the centre of the case to release the spring tension, then extract the pin. Repeat on the other side. Insert the new strap by aligning its terminals with the case lugs and press until the pins snap into position. If you prefer professional assistance, consult an authorised watchmaker.

Yes, provided the strap is constructed for a 19-millimetre lug width. Many high-quality aftermarket straps guarantee the same constructive precision as OEM straps. Milanostraps offers a selection of 19mm straps in alligator, calf leather and technical materials, all compatible with the IW3528-05 case and customisable to your preferences.

The durability of a leather strap depends on frequency of use, material type and storage conditions. High-quality alligator, worn daily, offers an average lifespan of 3–5 years before visible signs of wear emerge. Shell cordovan, owing to its structural density, may last 5–7 years. Vegetable-tanned calf leather, more susceptible to moisture absorption, has an average lifespan of 2–4 years but develops a fascinating patina. Casati Milano's 18-month warranty covers manufacturing defects and ensures ongoing support.
