Strap for La Grande Classique 29 Quartz Stainless Steel / PVD Red / White

The lug width is 16mm. This is a non-standard measurement in contemporary luxury watchmaking. To measure accurately, position a digital calliper between the lugs (the lateral pins on the case), measuring the exact internal distance. It is essential to verify twice to avoid purchasing incompatible straps.

Genuine alligator represents the finest choice, thanks to its characteristic texture and natural lustre that complement the classical identity. Alternatively, vegetable-tanned calf leather develops a unique patina over time. For sporty use, a rubber or NATO strap maintains correct proportions without compromising the minimalist character of the model.

The strap is changed using a spring bar remover tool. Insert the tool's tip into the small hole on the lug side, gently push the spring pin downwards, and the strap will disengage. Repeat on the opposite side. Install the new strap by inserting the pins on the opposite side, ensuring the spring pin clicks correctly into place.

Yes, any strap with a 16mm lug width is compatible with the L4.512.1.91.2. Verify that the strap's pins (spring bar) have a standard diameter of 1.8mm. Artisanal straps offer superior build quality and customisation compared to OEM straps, with the option to choose premium leathers and bespoke details.

A premium leather strap (alligator, calf, shell cordovan) typically lasts 3–5 years with regular use, provided basic maintenance is observed: avoid prolonged water exposure, protect from direct heat, and clean regularly with a dry soft cloth. The natural patina that develops is not deterioration but a sign of aesthetic ageing. Casati Milano's artisanal straps come with an 18-month warranty and extendable repair service.
