Strap for Da Vinci Perpetual Yellow Gold / White / Italian

The lug width of the IWC Da Vinci IW3750-02 is 19mm. This measurement represents the distance between the two horizontal pins that secure the strap to the case. To verify this measurement with precision, use a digital calliper positioned on the inner shoulder of the lug, excluding any protective spirals.

For the Da Vinci IW3750-02 in yellow gold 39mm, we recommend deep cognac alligator or calf leather with vegetable tanning in brown tones. Alligator offers formal elegance with a natural grain that does not compete visually with the case. Vegetable-tanned calf develops colour patina over time, amplifying the perception of discrete luxury. For sporting contexts, natural rubber with a velvety texture maintains functionality without compromising formal appeal.

To change the strap, use a spring bar tool to compress the horizontal lug pin within the spring mechanism. Tilt the tool slightly towards the inside of the case, reducing pressure on the outer shoulder of the lug. Remove the old strap and insert the new one by aligning the holes with the pins. Ensure the pin is fully closed before wearing the watch. A new strap with precise fixing points guarantees mechanical stability of the case.

Any strap with a 19mm lug width is compatible with the Da Vinci IW3750-02. Artisanal milanostraps.it straps are constructed to specifications that guarantee precise tolerances: lug holes are drilled with error margins below 0.5mm. We recommend verifying stitching quality along the strap body and leather flexibility before purchase.

The lifespan of a leather strap depends on frequency of use and tanning method. Alligator with vegetable tanning maintains structural integrity for 3–5 years with daily wear, developing a desirable ageing patina. Vegetable-tanned calf typically lasts 2–4 years before requiring replacement. Stitching quality and humidity acclimatisation directly impact longevity: straps stored in dry environments last longer. milanostraps.it offers an 18-month warranty on all artisanal straps.
