Frequently asked questions

What is the lug width of the Girard-Perregaux Laureato 81040-11-131-BB6A?

The lug width of this reference is 24mm. This measurement must be verified between the inside of the two lugs on the case where the strap inserts. It is the fundamental parameter for ensuring compatibility of any aftermarket strap with the watch.

Which strap is most suitable for the Girard-Perregaux Laureato 81040-11-131-BB6A?

The choice depends on usage and aesthetic preferences. An alligator or Tuscan calf leather on vegetable tanning enhances the case geometry with textural contrast. A NATO strap in fabric guarantees daily durability and resistance. For extreme humidity or heat conditions, FKM rubber is the most reliable technical solution. All materials must feature a 24mm lug width.

How do you change the strap on this watch?

The strap is replaced by unthreading the current one from the case lugs using a specific tool (spring bar tool) or by consulting a professional. The vertical lugs require gentle pressure to avoid scratching the case. Once freed, the new 24mm strap inserts into the same points. If you opt for a deployante clasp, it must be adjusted to your wrist before final assembly.

Is a 24mm aftermarket strap compatible with the Laureato 81040-11-131-BB6A?

Yes, provided the lug width is exactly 24mm. Milano Straps cinturini are specifically selected for this measurement. It is essential to verify that there is no excessive play between the strap and the lugs, nor friction that prevents smooth insertion. Premium leather straps require a 5-10 day break-in period.

How long does a leather strap last on a watch like the Laureato 81040-11-131-BB6A?

A leather strap's lifespan depends on usage, climate, and care. A superior quality leather (alligator, shell cordovan, Tuscan calf) subjected to moderate daily use reaches 3-5 years before requiring replacement. Humid climates or exposure to perspiration shorten the lifecycle. Proper drying after water exposure and periodic cleaning with damp cloths extend the material's longevity.
