Frequently asked questions
What is the lug width of the IWC Da Vinci IW9252-11?
The lug width is 19mm. This parameter indicates the distance between the vertical lugs of the case where the strap is inserted. It is the critical value for choosing compatible straps without gaps or excessive pressure.
What is the best strap for the IWC Da Vinci IW9252-11?
There is no absolute 'best', but choices consistent with your use. For formal occasions: black alligator. For sophisticated daily wear: vegetable-tanned calf in Bordeaux or Cognac tones. For versatility: FKM rubber in navy blue or anthracite. Rose gold accepts anything that is not chromatically flat.
How do you change the strap on this model?
The IW9252-11 uses standard 19mm spring bars. Position the watch with the case horizontal, use a dedicated tool (spring bar tool) to compress the internal spring of each lug, remove the old strap and insert the new one. It is a 2-minute operation if you have the correct tool.
Can I use an aftermarket custom strap on this IWC?
Yes, provided the lug width is 19mm. Custom artisanal straps (such as those created by the Casati Milano atelier) often offer superior construction quality to the originals, allowing you to choose leather, color, thickness and type of deployant buckle.
How long does a leather strap last on this watch?
Durability depends on intensive use and care. A quality alligator or shell cordovan lasts 4-6 years if worn regularly; vegetable-tanned calf 3-5 years. Rubber resists 5-7 years. Storing the watch in a climate-controlled drawer when not worn significantly extends the life of the strap.
