Strap for La Grande Classique Quartz 23 Gold

The lug width of the L4.191.7.11.6 is 12mm, measured between the inner lugs of the case. This dimension is characteristic of vintage European dress watches and requires specifically-sized straps to maintain the elegant and balanced proportions of the model.

For a vintage yellow gold piece like the L4.191.7.11.6, we recommend an authentic alligator strap in chestnut or burgundy tones: it creates elegant contrast with the metal and ages gracefully. Alternatively, vegetable-tanned calf develops a natural patina over time. For a more informal aesthetic, a Bemberg nylon NATO in navy blue is sophisticated without appearing casual.

Changing the strap requires a dedicated spring bar tool. Position the watch with the lugs facing upward, insert the tool into one of the side holes next to the lug, lift the elastic pin, then remove the old strap. Repeat on the other side and install the new strap. If you lack confidence, consult a professional watchmaker.

Yes, provided the strap is manufactured specifically for 12mm lug width. Many generic straps are calibrated for 14mm or 16mm and will not fit correctly. Milano Straps and the Casati Milano atelier produce custom straps sized precisely for your model, ensuring a perfect fit.

A quality leather strap—whether alligator or vegetable-tanned calf—typically lasts 3–5 years with daily wear. Longevity depends on care: keep the strap dry, avoid prolonged exposure to water and direct sunlight. A Casati Milano strap includes an 18-month warranty and can be restored or replaced.
