Strap for Da Vinci Perpetual White Gold / White / Italian

The IWC Da Vinci IW3750-07 features a lug width of 19mm. This dimension reflects the geometric proportions of the 39mm case and requires straps specifically compatible with this measurement. It is essential to measure the internal distance between the lug shoulders with precision to ensure a correct fit without forcing the strap.

For a white gold watch such as the Da Vinci IW3750-07, straps in alligator leather (for maximum formality), vegetable-tanned calf (for versatility and natural patina), or shell cordovan (for discrete luxury and durability) are recommended. The strap material must reflect the quality of the precious metal case. Avoid sport straps in rubber or fabric, which would compromise the design intention of the watch.

To change the strap, you must remove the lug pins using a spring bar tool. Position the watch on a soft surface, insert the tool into the suspended spring beneath the lug and gently lift it to release the pin. Repeat for both sides. Install the new strap by reversing the procedure. If you are not experienced, we recommend entrusting the task to a professional watchmaker to avoid damage to the white gold case.

Yes, you may use high-quality aftermarket straps provided they respect the 19mm lug width measurement. Milanostraps.it offers 19mm straps crafted from premium materials (alligator, calf, shell cordovan) compatible with the Da Vinci IW3750-07, customisable in dimensions, colours, and stitching finishes. The quality of the aftermarket strap must be consistent with that of the white gold case.

A high-quality leather strap, such as those offered by Milanostraps.it, has an average lifespan of 3-5 years with daily use, depending on the material and tanning method. Alligator and shell cordovan age gracefully and may last longer. Natural patina is part of the charm of leather; however, to extend useful life, it is advisable to protect the strap from prolonged exposure to moisture and to change it periodically. Atelier Casati Milano offers an 18-month warranty on all bespoke straps.
