Strap for Da Vinci Perpetual Rattrapante Yellow Gold / Silver / German

The lug width of the IWC Da Vinci IW3751-05 is 19mm. This dimension is the classic standard for Swiss dress watches of the previous generation. It is essential to verify that the strap is specifically designed for 19mm, as even half a millimetre of discrepancy compromises the aesthetic harmony between the lugs and the strap.

For a dress watch in yellow gold such as this Da Vinci, we recommend superior-grade alligator, crafted using vegetable tanning. The marked grain and patina that develops naturally create an authentic dialogue with the gold. Alternatively, shell cordovan offers natural rigidity and lustre that ages magnificently, whilst calfskin represents the choice for those preferring a more compact and sober texture.

To change the strap, position the watch face-down on a soft cloth. Using a dedicated spring bar removal tool or a very thin flat blade, apply gentle pressure on the lug to release the pin securing the strap to the lug. Once the old strap is removed, align the new one and reinsert the pin until it clicks into place. We recommend this operation be performed by a professional to avoid compromising the finishes.

Yes, any strap designed for 19mm lug width is compatible with the IWC3751-05. However, to achieve optimal aesthetic matching, choose artisanal straps designed to this specific geometry, as the Da Vinci's lugs feature a slight outward flare that requires precise strap curvature.

A quality watchmaking leather strap, such as alligator or shell cordovan, lasts an average of 5-7 years with daily use and adequate maintenance. Durability depends on humidity, frequency of use, and the material's ability to adapt. Artisanal Casati Milano straps are guaranteed for 18 months and can be regenerated over time through periodic cleaning and conditioning.
