Strap for Da Vinci Perpetual White Gold / Diamond / White / Italian

The IWC Da Vinci IW9253-10 features 19-millimetre lugs. This measurement is the standard specification for this reference and corresponds to the distance between the two metal supports where the strap attaches. Any aftermarket strap must strictly comply with this width to prevent stress on the white gold case.

For a white gold watch with a black dial, an alligator strap in black or dark brown represents the optimal choice. African alligator offers a velvety texture that naturally complements white gold, whilst vegetable-tanned calf leather provides a more structured alternative with a patina that evolves over time. Selection depends on personal aesthetics and intended use.

To change the strap, you must remove the spring bars connecting the strap to the lugs. Use a specialised spring bar tool or a sturdy needle: insert it into the spring to compress it and extract the bar. Proceed with caution to avoid scratching the white gold. If inexperienced, entrust the task to a specialist watchmaker.

Yes, a strap measuring 19 millimetres in width is fully compatible with the IWC Da Vinci IW9253-10, provided it respects construction tolerances of ±0.5 millimetres. However, the strap's quality—material, thickness, construction—must be proportionate to the nobility of the white gold watch. A poor-quality strap compromises the overall aesthetic effect.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 4–6 years with daily wear, considering exposure to humidity, perspiration, and constant flexing. Vegetable-tanned leather tends to age more visibly but remains functional beyond this period. A vulcanised rubber strap has superior longevity, lasting up to 8–10 years. Regular maintenance (cleaning, conditioning) significantly extends useful life.
