Audemars Piguet
CODE 11.59 26398BC.OO.D002CR.01— lug 20mm

The Audemars Piguet CODE 11.59 26398BC.OO.D002CR.01 features a 20 mm lug width. This measurement is native to the 42 mm case of this reference and must be respected with precision — recommended tolerance ±0.3 mm — to ensure correct installation and no lateral play between the strap and lugs.

For this white gold reference with grand complication, the ideal strap is Louisiana alligator with hornback or classic grain, in polished black or dark tobacco brown. Alternatively, polished box-calf leather offers a more urban and formal appearance. A white gold deployant clasp completes the pairing in a way that is consistent with the case's luxury.

The strap is removed using a dedicated spring bar tool with a thin tip, leveraging the spring bar inside the lug. Given the specific curvature of the CODE 11.59 lugs, it is recommended to proceed with caution to avoid scratching the white gold case. In case of doubt, it is preferable to rely on a watchmaker or Casati Milano atelier for the replacement operation.

Yes, there are high-quality aftermarket straps compatible with the 20 mm lug width of the CODE 11.59. Milano Straps offers a selection of artisanal straps in various leathers and finishes, made with curved terminals suited to the AP case profile. It is important to choose straps with properly shaped terminals to respect the lug geometry and achieve an aesthetic result consistent with the original.

A quality leather strap — alligator or box-calf tanned with traditional methods — with daily wear has an average lifespan of 18–36 months before the natural patina and flexing require replacement. By avoiding prolonged exposure to sweat, rain, and perfumes, and by carefully folding the strap, the useful life can be significantly extended. Milano Straps guarantees its straps for 18 months against manufacturing defects.
