Frequently asked questions

What is the lug width of the IWC Da Vinci IW3758-11?

The lug width of the IWC Da Vinci IW3758-11 is 20 millimetres. This specification is integral to the watch design and must be carefully verified when purchasing a compatible strap. To measure correctly, determine the external distance between the two lugs at their narrowest point.

What type of strap is most suitable for the IWC Da Vinci Perpetual Calendar in red gold?

Alligator in dark tones (black or dark brown) is the most coherent choice with the watch's constructive dignity. Alternatively, vegetable-tanned calf offers pronounced grain texture and organic ageing. For sporty contexts, we recommend high-quality FKM rubber rather than budget synthetic materials.

How do I change the strap on my IW3758-11 without damaging the case?

Use a dedicated spring bars extraction tool or consult a professional watchmaker. Position the watch on a soft surface, locate the small holes at the lug extremities, and gently press the tool to compress the internal spring. Extract the pin carefully, then insert the new strap and verify complete anchorage before wearing.

Are aftermarket straps genuinely compatible with the IW3758-11?

Yes, provided they respect the 20-millimetre lug width and are constructed to equivalent standards. Straps from certified ateliers guarantee total compatibility and superior fit compared to generic options. Always verify that the strap lacks excessive thickness at the passants, otherwise the case may experience irregular pressure.

How long does a leather strap last on a daily-worn watch?

A high-quality alligator or calf strap, properly tanned, maintains structural integrity for 2 to 4 years of daily use. Longevity depends on climate, humidity, frequency of wear and applied care. We recommend rotating multiple straps to reduce wear and periodically clean the leather with dedicated products.
