Strap for Da Vinci Perpetual Stainless Steel / White / English / Bracelet

The lug width of the IWC Da Vinci IW3750-21 is 19 millimetres. This measurement represents the distance between the two lateral lugs of the case and determines the width of the compatible strap. It is essential to verify this measurement before purchasing to ensure a perfect fit without lateral play.

For the Da Vinci IW3750-21, American alligator straps are recommended for formal elegance, vegetable-tanned calf for natural ageing patina, or NATO in ballistic nylon for sporting versatility. The choice depends on intended use: alligator for refined occasions, calf for sophisticated daily wear, NATO for sports and casual settings.

Strap replacement is performed using the lug spring bars. Using a dedicated tool (spring bar tool), compress the spring bar slightly to release it from the lug hole, extract the old strap, then insert the new one by aligning the holes. A simple but delicate operation: we recommend trusting experts to avoid scratching the case.

Yes, any strap with a 19-millimetre lug width is compatible with the Da Vinci IW3750-21, regardless of brand. Milanostraps offers artisanal 19mm straps ready for dispatch, customisable in material, colour, size and stitching thread, as well as bespoke creations at the Casati Milano atelier.

The lifespan of a leather strap depends on material and usage. A quality artisanal alligator or calf typically lasts 3-5 years with moderate daily use. Vegetable-tanned leather tends to age magnificently, becoming softer and more supple over time. Milanostraps offers an 18-month guarantee on handcrafted straps, with the possibility of subsequent reinforcements at the atelier.
