Strap for La Grande Classique Tonneau 22 Diamond

The lug width is 13 mm, one of the rarest sizing formats in modern watchmaking. This reduced dimension reflects the ultra-thin case profile and the minimalist philosophy of the model. To verify, use a digital calliper to measure the distance between the internal case lugs, or count the holes on a test strap: 13 mm typically corresponds to 5–6 standard holes.

Louisiana alligator is the canonical choice, as its ultra-fine grain enhances the perception of minimal elegance. For premium alternatives, shell cordovan offers natural lustre that contrasts beautifully with the brushed case. Polished calf provides versatile mirror finishing, whilst robust fabric NATO straps add daily versatility. The choice depends on intended use: formal (alligator), patina development (vegetable-tanned leather), casual (NATO).

The La Grande Classique features fixed lugs (non-removable horns). Strap replacement requires a spring bar tool to compress the internal spring and slide the strap from the lugs. It is inadvisable to perform this operation without the specific tool, as improper attempts may damage the case. We recommend entrusting the operation to a professional watchmaker or Casati Milano atelier.

Longevity depends on material and usage patterns. Quality alligator can last 5–8 years of daily wear before requiring leather rejuvenation. Shell cordovan, due to its structural density, offers similar or superior longevity. Brushed calf has slightly lower durability (3–5 years) for daily use. Vegetable-tanned leather lasts 4–7 years and develops fascinating patina over time. Factors such as humidity, sun exposure, and usage frequency significantly influence lifespan.
