Strap for Da Vinci Tourbillon Leonardo Rose Gold / German

The lug width of the IWC Da Vinci IW3752-17 is 19mm. This measurement is specific to the model and derives from the proportional relationship between the 39mm case diameter and the average wrist dimensions. Measuring the lug width is straightforward: place a ruler between the two vertical lugs where the strap attaches to the case. For the Da Vinci, the result will consistently be 19mm.

For the Da Vinci IW3752-17 in rose gold we recommend alligator leather with vegetable tanning in dark brown or black tones: the natural texture creates visual consonance with the watch's constructive precision, and the patina develops aesthetic character over time. An equally elegant alternative is vegetable-tanned cognac calf, which develops chromatic warmth that converges with the rose gold. For those preferring contemporary functionality, dark grey rubber offers maximum contrast and versatility.

Changing the strap on the Da Vinci IW3752-17 requires a spring bar tool. Identify the two vertical lugs on the case: one is typically fixed, the other mobile. Gently insert the tip of the spring bar tool into the small hole at the base of the mobile lug, pushing inward to release the internal spring. Remove the old strap and insert the new one by aligning it with the lugs. The procedure is reversible and requires no professional equipment, though we recommend extreme care with the rose gold case.

Yes, any strap with a 19mm lug width is compatible with the Da Vinci IW3752-17. Compatibility depends solely on lug width, not on brand or watch history. However we recommend selecting materials and finishes that respect the classic character of the rose gold case: high-quality alligator, calf and rubber are preferable to synthetic straps that would undermine the watch's qualitative investment.

A high-quality leather strap (alligator, calf, shell cordovan) with vegetable tanning has an average lifespan of 3-5 years with daily wear. This duration varies based on usage frequency, sun exposure and ambient humidity. Patina and wear marks are normal and testament to authenticity. To extend lifespan we recommend rotating multiple straps, allowing the leather to breathe, and occasionally applying balms designed for vegetable-tanned leather. The Casati Milano atelier provides an 18-month warranty on all bespoke straps.
