Strap for Superfast Chrono Split Second

The Chopard Classic Racing 168542-3001 features a lug width of 20 millimetres. This dimension is specific to this model and is not interchangeable with 18mm or 22mm watch straps. The 20mm width is a deliberate design choice to accommodate generously-spun leather straps while maintaining balanced proportions with the 45mm case.

The most appropriate strap depends on your intended use. For maximum elegance, we recommend natural alligator in black or cognac, which develops a unique patina over time whilst retaining its sporting character. For daily wear, vegetable-tanned calf leather offers comfort and tactile warmth. For racing authenticity, a dark blue NATO strap is ideal. The required width is invariably 20 millimetres.

Strap changing is straightforward and requires no specialist tools. Locate the spring bars at the lug ends—one on each side of the case. Using a spring bar tool or a pin, gently press the spring bar downwards to release the existing strap. Remove the old strap and align the new 20mm strap with the lug holes, then release the spring bar. Verify that both sides are securely fastened before wearing.

Yes, all quality aftermarket straps with a 20 millimetre lug width are compatible. Milanostraps.it offers an extensive range of natural leather, alligator, shell cordovan, and fabric straps, expertly crafted and available in custom length, monogram, and stitching thread personalizations. Compatibility is guaranteed by the standard 20mm lug width.

Durability varies according to material, frequency of wear, and environmental exposure. A vegetable-tanned calf leather strap typically lasts 2–4 years with regular daily wear. Alligator, being more robust, can reach 5–7 years or beyond. Shell cordovan exceeds 10 years with proper maintenance. Casati Milano straps are backed by an 18-month guarantee against manufacturing defects.
