Strap for La Grande Classique Tonneau 22 Yellow

The lug width of this model is 20 millimetres. This measurement represents the internal distance between the two metal lugs (spring bars) that attach the strap to the case. All compatible straps must have a width of exactly 20mm at the lug attachment point. You can verify this measurement manually with a calliper or consult the official technical specifications for this model.

The choice depends on the occasion and your personal preference. Alligator leather is the noblest solution: it develops a rich patina over time and pairs perfectly with the minimalist profile of the watch. For a sustainable alternative, we recommend vegetable-tanned calf leather. For summer, a cotton denim NATO strap brings elegant informality. Those engaged in sports may opt for a high-quality vulcanised rubber strap.

To change the strap, you must remove the lugs (spring bars) that secure it to the case. Use a specialist tool (spring bar tool) to apply pressure on one side of the internal lug, extracting it completely. Repeat the operation on the other side. Once removed, insert the lugs into the new 20mm strap and reinsert them into the case lugs, ensuring that the hooks of the lugs remain locked in the grooves.

Yes, absolutely. Quality aftermarket straps offer performance equal to or superior to original straps. The crucial element is lug width compatibility: it must be exactly 20mm. Choose straps made from noble materials such as alligator, vegetable-tanned calf leather or vulcanised rubber. Verify that the strap is compatible with your case dimensions before purchase.

Durability depends on the material, frequency of use and maintenance. A quality alligator strap typically lasts 3–5 years with daily wear, developing a fascinating patina over time. Calf leather has a similar lifespan but a more varied texture that ages more visibly. With occasional leather conditioning treatments (using specific non-aggressive creams), you can extend the strap's life. A cotton NATO strap lasts 2–3 years, whilst a quality vulcanised rubber strap lasts beyond 5 years.
