Frequently asked questions

What is the lug width of the IWC Da Vinci IW3750-24?

The lug width is precisely 19mm. This dimension is fixed and mandatory for strap and bracelet compatibility. It is measured by taking the internal distance of the case lug cavity from shoulder to shoulder of the spring bar passage.

Which strap is most suitable for the Da Vinci IWC IW3750-24 in red gold?

To enhance the red gold, we recommend Nile alligator with vegetable tanning, which develops a noble patina and captures the warm light of the case. Alternatively, dark brown or black dress calf leather provides elegant contrast without stylistic discord. For daily wear, fine-textured rubber or dark grey NATO straps offer versatility whilst maintaining coherence.

How do you change the strap on the Da Vinci IW3750-24?

Remove the lugs using a spring bar tool. Insert the tool's pin under the spring bar that connects the lug to the case, then gently extract. Replace the strap by aligning the new pins in the 19mm cavities and press until you feel a click. If inexperienced, consult a specialist to avoid damage.

Is an aftermarket 19mm strap compatible with the Da Vinci IW3750-24?

Yes, any strap with a 19mm lug width is geometrically compatible. However, verify that the passant (the part inserted between the lugs) is not excessively thick and respects a maximum thickness of approximately 6–7mm to avoid creating tension on the case. Artisanal straps have controlled and specifically dimensioned thickness.

How long does a leather strap last on the IWC Da Vinci?

A quality leather strap (alligator, calf, vegetable-tanned) with daily wear lasts 3–5 years before requiring replacement. Longevity depends on sun exposure, humidity, frequency of use and maintenance. Rubber lasts 4–7 years. Casati Milano straps, guaranteed for 18 months, maintain superior constructive characteristics over the medium-to-long term.
