Strap for La Grandes Classique Quartz 36 PVD / Champagne / Strap

The lug width is exactly 20 millimetres. This means your strap must measure 20mm at the base where it attaches to the spring bar. To verify, measure the internal distance between the two lugs on the case—the result must be 20mm. A strap that is too narrow will not fit properly; one that is too wide will not enter the lug slots.

The optimal choice depends on your wearing intention. Nile alligator is the most formal and authentic option: its distinctive grain pattern harmonizes perfectly with the 36mm case geometry. Shell cordovan develops an extraordinary patina over time. Vegetable-tanned veal leather offers everyday elegance, whilst NATO or rubber straps provide maximum practicality. Select according to primary use: evening requires alligator, office favours veal, sport suits NATO.

The process is straightforward. Using a spring bar tool, gently depress the spring bar from the top of the lug. The bar will retract and the strap will detach. Repeat on the opposite side. Insert the new strap by aligning its holes with the spring bars, then allow the bars to snap back into position. Ensure the strap is perfectly aligned before wearing the watch.

Yes, any strap with a 20mm lug width is compatible. However, ensure the strap thickness is appropriate for the 36mm case diameter—overly thick straps may not sit elegantly within the lug channels. Artisanal quality straps fit better than industrial alternatives because natural leather is more flexible and conforms to the case geometry.

A high-quality artisanal leather strap, with proper maintenance, lasts 3–5 years of daily wear. Alligator and shell cordovan resist longer—up to 7–10 years. Longevity depends on perspiration, humidity, sun exposure, and usage frequency. A strap worn intermittently may last 10+ years. Condition the leather every 6–12 months with specialist creams to maintain suppleness.
