The IW459308 reference maintains the traditional proportions of the Da Vinci line with a dial that integrates the moon phase display.

Frequently asked questions

What is the lug width of the IWC Da Vinci IW459308 (aka: IW459308, 4593-08, 459308)?

The lug width of the Da Vinci IW459308 measures exactly 18 millimetres. This measurement, which defines the space between the two spring bar attachments of the case, is fundamental for selecting compatible straps. An 18mm lug width ensures stable coupling and effortless removal, avoiding loosening or excessive friction.

Which type of strap pairs best with the Da Vinci IW459308 in rose gold?

For the rose gold Da Vinci IW459308, we recommend straps in brown or cognac alligator, vintage calf with articulated patina, or cigar-coloured nappak leather. Alligator emphasises the sophistication of the case, with a natural grain that reflects the complexity of rose gold. Vintage calf creates a temporal narrative consistent with the patina that rose gold will develop. Matte finishes, rather than polished, respect the classical identity of the model.

How do you change the strap on the IWC Da Vinci IW459308 (aka: IW459308, 4593-08, 459308)?

Obtain a spring bar removal tool, available from all watch retailers and from Milano Straps. Insert the flat blade into the small opening on the lower side of the lug, applying gentle pressure to release the internal spring. The bar will unlock and you can extract the original strap. Proceed in reverse with the new strap, ensuring the spring engages correctly with the case attachments. Avoid abrupt movements that could bend the bar. The process takes less than a minute once you are familiar with it.

Is it possible to use an aftermarket strap compatible with the Da Vinci IW4593-08?

Yes, any strap with an 18mm lug width is compatible with the Da Vinci IW459308. Milano Straps offers artisanal straps in Italian leather, fabric NATO, curved rubber and alligator, all designed for 18mm lugs. The quality of the aftermarket strap determines the aesthetic added value of the watch: premium leathers and artisanal finishes amplify the prestige of the IWC case. Each strap can be personalised in size, initials and choice of stitching thread.

How long does a leather strap last on the Da Vinci IW459308?

Durability depends on the quality of the leather and daily wear. A premium leather strap (alligator, vegetable-tanned calf) maintains structural integrity for 3–5 years of regular use. Factors such as humidity, sun exposure, frequency of changes and maintenance affect the speed of deterioration. Patina is natural and desirable; cracks or tears require replacement. Milano Straps guarantees 18 months on straps made in the atelier, with the possibility of subsequent repairs and upgrades.
