Strap for Modello Quattro U4S-8O Tuscany

The lug width of the Modello Quattro UWK-U4S-8O is 22 millimetres. This measurement represents the distance between the two metal pins that support the strap. It is essential to verify this specification before purchasing an aftermarket strap to ensure complete compatibility.

The ideal strap depends on usage and personal preference. For daily elegance, we recommend alligator leather or vegetable-tanned calf, which enhance the minimalist design of the brushed steel case. For sporting versatility, a military-grade cotton NATO maintains the understated aesthetic. The strap must feature a 22mm lug width and appropriate thickness to preserve case proportions.

To change the strap, use a dedicated tool or spring bar tool. Insert the tip gently into the small lateral hole of the lug pin to compress the internal spring, then extract the pin. Repeat on the other side. Insert the new strap (always 22mm width) by positioning the compressed pin until it clicks into place. The operation requires precision but is straightforward.

Yes, quality aftermarket straps with a 22mm lug width are perfectly compatible. Milanostraps.it offers a specialised selection of artisanal straps in various materials: noble leather, technical NATO, vulcanised rubber. The key is verifying the 22mm specification and selecting thicknesses consistent with the proportions of the 41.50mm case.

The lifespan of a leather strap depends on daily use and material quality. A high-quality vegetable-tanned calf or alligator strap can last 3–5 years in daily wear without issues, developing a desirable patina over time. A cotton NATO strap offers superior durability if subjected to abrasion, though less amenable to aesthetic development. Regular maintenance (leather conditioning, cleaning) significantly extends useful life.
