FAQ

What is the lug width of the Audemars Piguet CODE 11.59 26398OR.OO.D002CR.01?

Reference 26398OR.OO.D002CR.01 is fitted with 20 mm lugs. To verify this on your own timepiece, a digital caliper positioned between the inner walls of the lugs, parallel to the caseback, at the strap attachment point is recommended.

What is the best strap for the Audemars Piguet CODE 11.59 26398OR.OO.D002CR.01?

For this grand complication in rose gold, smooth alligator leather with a polished finish is the most coherent choice with the craftsmanship level of the AP 1000SQ caliber. Box-calf leather is a characterful daily alternative, while vulcanized rubber offers resistance without sacrificing elegance. The rose gold deployant clasp completes the pairing.

How do you change the strap on the Audemars Piguet CODE 11.59 26398OR.OO.D002CR.01?

The strap is removed using a dedicated flat-tipped tool or a thin-blade screwdriver to slide the spring bars through the lugs. For a rose gold piece of this complexity and value, it is recommended to rely on an expert watchmaker or the Casati Milano atelier to avoid scratches on polished surfaces.

Are there aftermarket straps compatible with the Audemars Piguet CODE 11.59 26398OR.OO.D002CR.01?

Yes. Aftermarket 20 mm straps with straight or slightly curved ends are compatible with this reference. On Milano Straps you will find a selection of handcrafted 20mm straps made from high-quality materials, designed to fit the sculpted lugs of the CODE 11.59 without tension or play.

How long does a leather strap last on an Audemars Piguet CODE 11.59 26398OR.OO.D002CR.01?

A high-quality alligator or calf leather strap, with regular use, has an average lifespan of 18-36 months before flexing in the bend area begins to mark the structure. Rotating between two straps and using a deployant clasp — which reduces mechanical stress during opening — can significantly extend the strap's life. Casati Milano offers an 18-month warranty on manufacturing defects.
