Strap for Da Vinci Perpetual Red Gold / Diamond / Paved / English

The IWC Da Vinci IW8153-17 features a lug width of 19 millimetres, an intermediate dimension not particularly common in classical watchmaking. To verify with certainty, use a mechanical calliper, measuring the distance between the two spring bars in their original seating. This precision is essential before any aftermarket strap purchase.

Alligator represents the most advised aesthetic choice: natural scales create visible texture that emphasises the nobility of the metal. For formal contexts, black or dark grey alligator harmonises perfectly with white gold. Alternatively, superior quality calf leather (Hermès-grade) offers tactile discretion, whilst Japanese shell cordovan develops extraordinary patina over time.

Strap change occurs by gently removing the spring bars present at both extremities of the lug. You may use a dedicated tool (spring bar removal tool) or consult an watchmaker to avoid damage. The bars must be inserted into the new strap following the same logic, ensuring the passant aligns with the case lug. A 19mm strap guarantees absolute compatibility.

Yes, it is possible to use artisanal quality straps provided they are compatible with the 19-millimetre lug width. MilanoStraps offers a dedicated collection of 19mm straps customisable in leather (alligator, calf, cordovan, vegetable-tanned), available with various finishing options and buckles. Verification of dimensional compatibility before purchase is paramount.

Lifespan varies depending on material and usage. Quality alligator guarantees 4-6 years of daily wear before visible wear; shell cordovan resists 5-7 years whilst developing fascinating patina; vegetable-tanned calf lasts 3-4 years with regular maintenance. Factors such as humidity, perspiration and sun exposure influence ageing. MilanoStraps offers 18-month warranty on all artisanal straps.
