Strap for Da Vinci Perpetual Stainless Steel / White / Italian

The lug width (ansa width) of the IWC Da Vinci IW3750-12 is 19 millimetres. To verify this, measure the distance between the centres of the two pins that attach the strap to the case lugs: it must be exactly 19mm. This parameter is decisive when purchasing a compatible aftermarket strap.

For the Da Vinci IW3750-12, vegetable-tanned alligator is the reference choice: it develops a natural patina over time, acquiring chromatic depth that reflects the instrument's constructive vocation. If you prefer versatility, vegetable-tanned calf leather in cognac or hazelnut tones is universally appropriate. For more informal use, NATO straps in grey or blue canvas maintain technical coherence with the minimalist dial.

Loosen the fixing screws inside the case lugs (often visible through transparency). Extract the pins from the old strap, leveraging gently with a blunt, non-cutting tool. Insert the new pins into the new strap, ensuring that the extremities align perfectly with the lug holes. Reinsert the pins and tighten the screws with moderate pressure, avoiding over-tightening which could damage the steel finish.

Yes, provided the width is 19 millimetres and the thickness does not exceed the physical limit of the lugs. Milano Straps artisanal straps are constructed specifically for this size and tested for tolerance. Always verify that the pins slide into the lugs without forcing: a well-constructed strap should move inside the lugs with minimal play.

A natural leather strap of quality (alligator, vegetable-tanned calf) lasts 3-5 years with daily use and standard maintenance: periodic drying after water contact, protection from chemical solvents, application of balm on a biannual basis. Durability depends on sun exposure, body perspiration and frequency of use. With careful attention, the leather acquires natural character without premature degradation.
