IWC
Da Vinci IW3528-02— lug 19mm

The lug width of the IWC Da Vinci IW3528-02 is precisely 19 millimetres. This measurement is standard and non-negotiable for this model. To verify, measure the internal distance between the two metal lugs: it must be exactly 19 mm. Any aftermarket strap must correspond to this specification, otherwise it will not insert correctly into the lugs.

The best strap depends on intended use and personal preference. For formal elegance, we recommend an alligator strap dyed in cognac brown or vegetable-tanned calf in black. For superior durability and magnificent ageing, shell cordovan is the absolute excellence. For daily wear, a grey calf or blue NATO fabric maintains practicality without sacrificing character. A deployante clasp is strongly recommended for security of wear.

Changing the strap requires removal of the spring bars that connect the strap to the lugs. Use a dedicated spring bar tool to extract the old bar, then insert the new 19 mm strap and reinsert the bar. Ensure the bar is perfectly seated on both sides. If you feel uncertain, entrust the work to a professional watchmaking laboratory that will complete the service in minutes.

Yes, any aftermarket strap with a 19 mm lug width is mechanically compatible. However, consider aesthetics: the Da Vinci is a classical timepiece that deserves superior materials. We recommend alligator, vegetable-tanned calf, or shell cordovan rather than synthetic leathers or low-quality fabrics. Also verify the thickness of the leather to ensure smooth insertion into the lugs.

Lifespan depends on material and usage. Premium-quality alligator, with ordinary maintenance, lasts 5-7 years of daily wear. Vegetable-tanned calf may last 3-5 years, while shell cordovan, thanks to its structural compactness, can exceed 10 years with appropriate conservation. Factors such as humidity, frequency of wear, and storage significantly influence longevity. Our 18-month warranty covers defects in construction and workmanship.
