Strap for Da Vinci Perpetual Rattrapante Platinum / Blue / French

The lug width of the IWC Da Vinci IW3754-08 is 20 millimetres. This measurement represents the internal distance between the two lugs of the case and is the standard connection width for the strap on this particular model. To verify compatibility with any strap, measure the inner gap between the case lugs: it must be exactly 20 millimetres. All straps offered by Milano Straps in this size will fit your watch perfectly.

For a platinum watch with a perpetual calendar complication, we recommend black or dark brown alligator to maximise aesthetic restraint, or vegetable-tanned calf leather if you desire a hide that develops patina over time. Shell cordovan represents the choice for those who appreciate material rarity and natural chromatic evolution. The texture of alligator, characterised by regular osteoderms, dialogues particularly well with the cool-neutral surface of platinum, creating formal harmony.

Strap replacement is performed by removing the spring bars that connect the strap to the case lugs. Using a dedicated spring bar tool, gently press the bar inward to release the strap from the first lug, then proceed similarly on the opposite lug. Insert the new strap by aligning the hole with the spring bar, and press the bar until you hear a subtle click confirming secure positioning. Alternatively, the specialists at Casati Milano can perform this operation with manual precision, ensuring protection of both case and strap.

Yes, the IW3754-08 is fully compatible with quality aftermarket straps, provided the lug width is 20 millimetres. Milano Straps offers a range of artisanal straps specifically crafted for this measurement, available in premium materials (alligator, calf leather, shell cordovan) and customisable in length, initials, and stitching thread. The use of aftermarket straps does not compromise any IWC warranty.

The lifespan of a leather strap depends on usage, material quality, and environmental conditions. A quality alligator or vegetable-tanned calf strap, with appropriate maintenance (protection from excessive moisture and direct sunlight), typically lasts 5–8 years of regular use. Shell cordovan, owing to its dense fibrous structure, tends to last considerably longer. To extend strap longevity, avoid prolonged exposure to fresh water, occasionally apply hide-specific conditioning balms, and remove the watch during activities that expose it to intense mechanical stress. Milano Straps provides an 18-month guarantee on all straps crafted by Casati Milano.
