Strap for Laureato 42 Automatic Stainless Steel / Blue / Alligator

The lug width of the Girard-Perregaux Laureato 81010-11-431-BB6A is 27mm. This dimension is determined by the integrated geometry of the octagonal case and represents the standard construction specification for this model. Accurate measurement requires positioning a calliper perpendicularly between the two spring bar holes, from the centre of one hole to the centre of the other.

The ideal strap depends on intended use and personal style. Alligator leather with vegetable tanning represents the most elegant and formal option, whilst cognac calf provides everyday versatility. For sports contexts, NATO fabric straps in technical materials enhance the Laureato's sporting heritage. FKM rubber ensures maximum practicality in humid or variable environments.

The process requires specific tools: a dedicated spring bar removal tool to disengage the bars from the case lugs. Position the watch on a soft surface, insert the tool tip into the spring bar release hole, lift gently and extract the current strap. Insert the bars into the new strap and press until the safety click engages. We recommend having your first replacement performed at an authorised service centre or Casati Milano atelier.

Yes, aftermarket straps may be used provided they meet the exact 27mm lug width specification. We recommend selecting handcrafted straps with precise construction and noble materials—alligator, vegetable-tanned calf, NATO in cordura—to maintain the watch's aesthetic integrity. Milanostraps.it offers a curated selection of 27mm straps manufactured to high quality standards.

Leather strap longevity depends on frequency of use, moisture exposure, and tanning quality. An alligator or vegetable-tanned calf strap worn daily under normal conditions typically lasts 3-5 years before requiring replacement. Leather develops a natural patina over time, improving in character; prolonged exposure to water or humidity significantly shortens lifespan. Periodic maintenance with specialist products extends strap longevity.
