Strap for Da Vinci Perpetual Rattrapante Platinum / Silver / German

The IWC Da Vinci IW3751-02 has a lug width of 19 millimeters. This width is specific to the series and should be verified with a caliper before ordering a replacement strap, as even a 0.5 mm discrepancy affects the fit between the case lugs.

Premium alligator remains the traditional choice for its fine grain and structural rigidity. Alternatively, vegetable-tanned calf offers a richer patina over time, while nitrile rubber ensures water resistance and vibration absorption for daily wear. All must respect the 19mm lug width.

The change requires a spring bar tool and a stable work surface. Position the watch horizontally, insert the tool into the small hole under the lug, gently press to release the internal spring, remove the old spring bar, then insert the new strap by aligning the pins with the case guides. If you lack confidence, consult an atelier such as Casati Milano.

Yes, provided they respect the 19mm lug width and adequate total length for your wrist (typically 75-100mm per side). Premium artisanal straps, such as those from Milano Straps with vegetable tanning or alligator, guarantee full compatibility and durability of 5-7 years with ordinary maintenance.

A premium alligator or calf strap, with vegetable tanning and triple-stitch construction, lasts 5-7 years with regular wear. Longevity depends on factors such as moisture exposure, perspiration, frequency of wear, and maintenance (periodic cleaning, drying, conditioning with natural wax). Casati Milano guarantees 18 months on its bespoke work.
