Strap for La Grande Classique Tonneau 22 Stainless Steel

The lug width is 18 millimetres. This dimension is measured between the two metal pins on the inside face of the lug and represents the exact standard for compatibility. On milanostraps.it, all straps are certified for this measurement.

For this ultra-thin and minimalist case, alligator leather with vegetable tanning or chromium tanning offers the finest aesthetic balance. Black or dark brown alligator amplifies the design's purity. For versatility, Italian calfskin with natural patina evolves magnificently over time. For informal wear, a solid canvas NATO remains a practical choice without compromising elegance.

The change requires a precision tool (a small screwdriver or professional strap changer) to remove the pins from the lug seats. The tolerance is tight given the 18mm measurement, so careful operation is recommended. At Casati Milano, the Milan-based atelier, strap changes are performed by appointment with compatibility verification and fitting guarantee.

Yes, provided they strictly respect the 18mm lug width. On milanostraps.it, the 18mm collection is entirely tested for this model and includes premium options (alligator, shell cordovan, calfskin) as well as more informal choices (NATO, rubber). Customisation is available for sizing, initials, and finishing.

An alligator or calfskin strap with vegetable tanning typically lasts 5-8 years in daily wear, depending on climate and wearing habits. Sun exposure accelerates ageing, whilst humidity can compromise the fibre. By commission, Casati Milano provides an 18-month warranty on made-to-measure straps, plus restoration and re-stitching services to extend the accessory's lifespan.
