FAQ

What is the lug width of the IWC Da Vinci IW3750-32?

The lug width of the IW3750-32 is precisely 19 millimetres. This exact measurement requires bespoke straps and does not permit approximation. Measuring it correctly—distance from lug to lug on the case—ensures perfect compatibility and minimal mechanical stress on the case lugs.

Which strap is most suitable for the Da Vinci IW3750-32?

Alligator in dark brown or vegetable-tanned calf leather represent the canonical choices to enhance the Da Vinci's elegance. Shell cordovan, ageing towards cognac tones, complements the cylindrical design with rich patina. For versatility, a NATO strap in technical canvas offers practicality whilst maintaining a minimalist profile.

How do you change the strap on an IWC Da Vinci IW3750-32?

Position the watch on a table with the lugs facing upward. Use a dedicated tool—a spring bar tool—to compress the internal springs of the lugs and extract them. Insert the new strap from the opposite side, ensuring the pins are fully inserted and snap into the case suspensions.

Are aftermarket straps compatible with the Da Vinci IW3750-32?

Yes, provided they respect the 19-millimetre lug width specification. Artisan Milano Straps are handcrafted to this precise width, guaranteeing perfect compatibility. Avoid adapters or improvised solutions that may stress the original lugs.

How long does a leather strap last on the Da Vinci IW3750-32?

A quality leather strap—alligator, shell cordovan or vegetable-tanned calf—resists 3–5 years of daily wear, developing rich patina. Longevity depends on solar exposure, humidity and frequency of use. Light maintenance with neutral balm significantly extends its life; the strap is not consumable but an instrument that improves over time.
