Strap for Da Vinci SL Stainless Steel / Black

The lug width (misura ansa) of the Da Vinci IW3528-04 is 19 millimetres. This dimension is determined by the case width and integrated lugs. To verify it, use a digital calliper and measure the internal distance between the original bracelet attachment pins.

It depends on intended use and personal preference. For formal aesthetics, we recommend honey or dark alligator or vegetable-tanned calf leather that develops natural patina. For sporty contexts, a neutral-tone NATO or technical rubber strap emphasises the watch's versatility. Shell cordovan, if available in 19mm, offers a unique brilliance that harmonises perfectly with the case's brushed steel.

The Da Vinci IW3528-04 uses standard spring bars for strap attachment to the lugs. Use a spring bar tool to compress the internal spring, remove the old strap and insert the new one. Ensure the new strap's ends align perfectly with the lugs: a tolerance of a few tenths of a millimetre is critical for stability.

Yes, provided the lug width is exactly 19 millimetres. High-quality aftermarket straps (such as those from Casati Milano) are compatible with the Da Vinci IW3528-04 and often allow superior aesthetic customisation compared to the original bracelet. Always verify that the strap is made from premium leather or material and fitted with appropriate spring bars.

The lifespan of a leather strap depends on frequency of use, climate and material choice. Quality artisanal calf and alligator typically last 3–5 years of daily wear. Shell cordovan and vegetable-tanned leathers age visibly but remain functional for 7–8 years. Direct exposure to sweat, water and sunlight shortens useful life. Casati Milano guarantees straps for 18 months and offers replacement and restoration services.
