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

The lug width of the IWC Da Vinci IW3751-08 is 19 millimetres. This measurement should be verified using a digital calliper positioned perpendicular to the spring bar holes, measuring from inside to inside. A 19mm strap ensures precise insertion without lateral play or movement.

For a yellow gold Da Vinci, Brazilian alligator leather with vegetable tanning represents the most appropriate aesthetic choice: the marked grain naturally complements the patina of the gold, and the leather ages beautifully, creating a harmonious palette over time. Alternatively, vegetable-tanned calf leather offers greater understated elegance, whilst burgundy shell cordovan suits those seeking superior durability with sporting character.

Strap replacement is performed by removing the two lateral spring bars that connect the strap to the case lugs. Use a dedicated spring bar tool to release the compressed pin, then extract the old strap. Insert the new strap by aligning the holes, reinsert the spring bar (ensuring both ends are fully seated), and verify that the piece is centred. Avoid hammers or improvised tools to prevent damage to the yellow gold case.

Yes, any strap with a 19mm lug width is compatible with the Da Vinci IW3751-08, regardless of brand. However, for this yellow gold case and with these complications, it is recommended to choose straps in superior leather quality (alligator, shell cordovan, vegetable-tanned calf) and to avoid synthetic materials or coarse fabrics, which would compromise the visual harmony of the piece.

Lifespan depends on the leather and usage: vegetable-tanned alligator or shell cordovan, if well maintained and worn non-daily, last between 5 and 8 years. More delicate calf leather may show aesthetic wear signs after 3-4 years of regular wear. Periodic maintenance (gentle cleaning, conditioning every six months) significantly extends strap life. The Casati Milano atelier offers an 18-month warranty on bespoke straps made to measure.
