IWC
Da Vinci IW3528-06— lug 19mm

The IWC Da Vinci IW3528-06 has a lug width of 19mm. This rare dimension identifies medium-sized watches within the IWC collection and is essential for selecting a compatible strap. To verify this measurement, measure the space between the two lugs of the case using a calliper: the result must be exactly 19 millimetres.

The ideal strap depends on your use case and dial colour. Alligator in brown or cognac tones is the classic choice: its natural texture harmonises perfectly with the case's classical proportions. Vegetable-tanned calf offers a patina that ages organically over time, developing character. NATO canvas ensures versatility and durability. For formal occasions, we recommend alligator or calf leather; for daily or sports use, NATO or FKM rubber.

The strap is changed by removing the two pins (bars) that connect the strap to the watch's lugs. Use a dedicated spring bar tool: insert the tip into the groove beneath the pin and apply gentle pressure to extract it. Once the old strap is removed, align the pins of the new strap with the lugs and snap them into position. The operation requires care to avoid damaging the lugs.

Yes, provided it has a 19mm lug width. Milano Straps offers a comprehensive collection of high-quality compatible straps, crafted from alligator leather, calf, shell cordovan, NATO canvas, and FKM rubber. Straps are customisable in length, initials, and stitching thread colour. Atelier Casati Milano also creates made-to-measure straps with personalised consultation and an 18-month guarantee.

Lifespan depends on material and usage. A quality alligator strap, with regular care, lasts 4–6 years of daily wear. Calf leather tends to wear slightly faster (3–5 years), whilst shell cordovan, thanks to its density, can last 6–8 years. FKM rubber offers the best longevity (8+ years) if not exposed to extreme temperatures. Regular maintenance – cleaning with a soft damp cloth and conditioning with specialised creams – significantly extends the strap's lifespan.
