Strap for Da Vinci Perpetual Rattrapante Platinum / Silver / Italian

The lug width of the IWC Da Vinci IW3754-10 is 20 mm. This dimension allows for the use of structured leather straps and premium materials while maintaining balanced proportions with the 41.50 mm case. The measurement is taken by positioning a calliper at the inner point of the case lug, perpendicular to the lug length.

For the Da Vinci in platinum, we recommend an alligator strap in deep black or cognac, which dialogues with the luminosity of the precious metal. Alternatively, superior quality calf leather with vegetable tanning offers natural ageing over time and develops characteristic patina. Polished shell cordovan represents a modern choice combining elegance with superior durability and minimal maintenance.

To change the strap, use a spring bar removal tool (available in complete kits or from specialist retailers). Position the tool in the lower slot of the spring bar and apply gentle pressure to depress the internal spring. Once the lug is freed, remove the old strap and insert the new one, ensuring the spring bar clicks correctly into place. We recommend caution to avoid scratching the platinum case during the operation.

Yes, all straps with 20 mm lug width are compatible with the IW3754-10, including quality aftermarket straps. On milanostraps.it you will find a selection of 20 mm straps customisable in sizes, colours, initials and stitching thread type. Verify that the new strap is fitted with suitable spring bars for mounting and that the material is appropriate for your intended use.

The lifespan of a leather strap depends on the tanning type and usage pattern. A calf leather strap with vegetable tanning, with moderate daily use, lasts an average of 3-5 years before replacement is necessary (develops patina but remains functional beyond this period). Quality alligator can last 5-8 years. Shell cordovan, being denser leather, easily reaches 7-10 years of regular use. Periodic maintenance (cleaning, reconditioning) significantly extends the lifespan of any strap.
