Strap for Da Vinci Tourbillon Platinum / Italian

The lug width of the IWC Da Vinci IW3752-10 is 19 mm. This dimension represents the physical spacing between the spring bar holes where the strap attaches to the watch case. Accurate measurement of the case attachments is essential before ordering an aftermarket strap, as an incorrect size would result in unwanted slippage or inability to secure the strap properly.

For a platinum case such as the IW3752-10, we recommend straps in medium brown or cognac alligator, which naturally complement the neutral tone of this noble metal. Alternative refined options include vegetable-tanned shell cordovan in dark shades or fine-grained calf leather. We advise against saturated colours or dense patterns that would visually compete with the complexity of the chronograph dial.

The strap is secured using two spring bars (lugs pins) that connect the watch case lugs. To remove the strap, you need a specific tool (pin remover) to withdraw the spring bars from the lateral cavities. Subsequently, the new strap is installed by threading the spring bars into its openings and repositioning them in the case lugs. If you lack experience, we recommend entrusting this operation to a qualified watchmaker or Casati Milano to avoid scratching the case.

The lifespan of a leather strap depends on tanning quality, the wearer's lifestyle, and climatic conditions. High-quality vegetable-tanned leather, such as shell cordovan or alligator, can last 3–5 years with moderate wear and proper maintenance (avoiding prolonged water immersion and protecting against excessive perspiration). Premium straps crafted by specialised artisans, such as those from Casati Milano, benefit from an 18-month warranty and are constructed to develop a natural patina that enhances their aesthetic appeal over time.
