Strap for Da Vinci Tourbillon Yellow Gold / French / Bracelet

The lug width of the IWC Da Vinci IW9267-04 is 19mm. This measurement represents the distance between the two lugs where the strap is attached. You can verify this by measuring with a digital calliper the distance between the case lugs once the original strap has been removed.

For a yellow gold IWC Da Vinci 39mm, we recommend natural brown alligator, vegetable-tanned calf in aged finish, or burgundy shell cordovan. These materials create noble chromatic contrast with the golden case and lacquered blue dial. Avoid caramel or beige tones that dilute the visual impact.

Use a spring bar tool to extract the two lugs that hold the current strap. Insert the small blade into the access hole on the case, push the lug laterally and lift the strap. Repeat from the other side. To install the new strap, align the holes with the lugs and press until you hear the click of closure.

Yes, provided it respects the 19mm lug width. Quality aftermarket straps maintain tight tolerances (±0.1mm) to avoid play or excessive tension. Check that the strap does not show forced curvatures at the case attachment and that any deployant clasp does not create conflicts with the golden lugs.

A quality leather strap (alligator, calf, shell cordovan) on a daily-worn watch lasts 3-5 years before requiring replacement. Durability depends on exposure to sweat, moisture, and frequency of wear. Vegetable tanning tends to age gracefully, developing patina, while chrome-tanned leather requires more frequent maintenance to preserve flexibility.
