Strap for Da Vinci Perpetual White Gold / White / German

The lug width of the IWC Da Vinci IW3750-06 is 19 millimetres. This measurement is essential to ensure compatibility with aftermarket straps. To verify it correctly, use a digital calliper to measure the distance between the inner lugs of the case, not the external width. This standard allows access to a wide range of customised straps.

For a Da Vinci IW3750-06 in white gold, alligator is the most natural choice due to its fine, regular grain that dialogues perfectly with the refined geometry of the case. Excellent alternatives include calf leather with vegetable tanning in dark brown or cognac tones, or shell cordovan for those who appreciate densely structured leathers. Avoid straps with excessively glossy finishes or saturated colours that distract from the subtle elegance of white gold.

Changing the strap requires the use of a lug-pin removal tool. Position the watch on a stable support, locate the small holes in the case on either side of the lug, and use a precision instrument (removable pin tool or small screwdriver) to gently push the pin out. Once the pin is removed, the old strap detaches easily. Insert the new strap by aligning the holes and reinsert the pin until it locks. If you are unsure, entrust the task to a professional watchmaker to avoid damage to the lugs.

Quality aftermarket straps do not replicate the IWC brand but achieve comparable or superior construction standards in leather workmanship and measurement precision. Alligator, calf or shell cordovan straps crafted by specialised small workshops often offer customisation, choice of leathers and finishes that the mass market does not allow. Technical compatibility is guaranteed (19mm width), whilst perceived quality depends on the material chosen and artisanal craftsmanship.

The lifespan of a leather strap depends on the material and context of use. A quality alligator strap with vegetable tanning, with regular care (avoiding prolonged moisture, gentle cleaning), typically lasts 3-5 years of regular daily wear. Shell cordovan, being more resistant to cracking, can reach 5-7 years. Calf is more delicate, with a lifespan of 2-4 years. The ageing of leather is predictable and fascinating: over time it develops patina and character, telling the story of use. Well-crafted straps can be renewed by a workshop by replacing the underside without altering the body of the leather.
