Strap for Da Vinci Perpetual White Gold / Diamond / Paved / German

The lug width of the IW8153-13 is 19mm. This dimension is specific to this generation of the Da Vinci collection in white gold and is less common than the standard 18mm or 20mm widths. You can verify it by measuring the distance between the two lugs with a digital calliper. It is essential to confirm this measurement before ordering an aftermarket strap to ensure perfect compatibility.

Dark brown alligator (Cognac or Tobacco shade) is the most natural choice for a Da Vinci in white gold: the fine grain paired with cold-toned metal creates impeccable aesthetic cohesion. Alternatively, Bordeaux shell cordovan offers superior compactness and a predictable patina over time. Avoid saturated colours or black entirely, as these create visual conflict with white gold.

Obtain a professional spring bar tool. Position the watch face-up on a soft surface. Insert the tool into the lateral spaces of the lug and press gently inward to release the spring bar. Extract the bar carefully, then repeat on the opposite side. When installing the new strap, ensure both spring bars are seated firmly in their housing. If uncertain, consult a certified watchmaker.

Yes, and it is recommended. Bespoke 19mm aftermarket straps offer superior construction quality compared to original IWC straps, with the opportunity to select premium materials such as alligator, shell cordovan, and vegetable-tanned leather. Milanostraps offers a selection of compatible 19mm straps, customisable and made to measure. For an even more refined experience, Casati Milano creates straps on commission.

Durability depends on material and usage. Quality alligator or shell cordovan lasts 5–8 years with moderate daily wear. Vegetable-tanned leather evolves aesthetically over time and remains functional for 4–6 years before replacement is needed. Calf leather, being more delicate, lasts 2–4 years. Occasional or seasonal use significantly extends these timeframes. Regular maintenance—gentle cleaning and air-drying—preserves the structural integrity of the leather.
