Strap for Da Vinci Perpetual Stainless Steel / Black / Italian

The lug width of the IWC Da Vinci IW3750-29 is 19 millimetres. This measurement is taken by positioning a digital calliper between the two metal lugs located at the 12 and 6 o'clock positions on the case. All compatible straps must measure exactly 19mm.

For this timepiece, alligator leather with French tanning is the ideal choice: the regular texture enhances the geometric purity of the case. Shell cordovan is excellent for those seeking natural patina development over time. Vegetable-tanned calf leather offers daily versatility. For intensive use, rubber or NATO straps in neutral tones (dark blue, black, anthracite grey) ensure practicality without aesthetic compromise.

Strap replacement requires a spring bar tool: insert the flat pin between the case lug and the spring bar supporting the strap, apply gentle pressure to release tension, then extract the strap. Reverse the procedure to install the new strap. It is advisable to perform this operation on a soft surface to prevent damage to the case.

Yes, any strap with a 19-millimetre lug width is mechanically compatible with the Da Vinci IW3750-29. We recommend choosing straps that respect the visual proportions of the case (39mm diameter): thicknesses between 3.5 and 4.5 millimetres, finishes in noble materials, and <a href='/pages/termine-glossario/deployante'>deployante</a> buckles that maintain constructive elegance.

The lifespan of a leather strap depends on usage, climate, and maintenance. A quality alligator or calf leather, with vegetable or French tanning, maintains functionality for 3-5 years with daily wear and regular care. Shell cordovan can last up to 7-8 years. Maintenance consists of monthly cleaning with a damp cloth and occasional application of specific balms. Natural wear on the leather at the lugs is a sign of nobility, not a defect.
