Audemars Piguet
CODE 11.59 26393QT.OO.A064KB.01— lug 20mm

The lug width of the Audemars Piguet CODE 11.59 reference 26393QT.OO.A064KB.01 is 20 mm. This is the native case width and must be respected to ensure correct strap positioning between the lugs without play or lateral tension.

For the hybrid ceramic and steel case of the CODE 11.59, embossed alligator in midnight blue or tobacco brown is the most coherent choice with the haute horlogerie aesthetic of the AP 4401 flyback movement. Alternatively, structured calf box grain with brushed steel buckle offers a sartorial result of great elegance. For sports use, vulcanized rubber is preferable to nylon.

The strap is replaced using a lever or pointed spring bar tool, inserting the tool into the lateral slot of the lugs to compress the spring bar springs. The CODE 11.59 adopts standard 1.8 mm spring bars, so it is compatible with common watchmaker tools. It is recommended to work on a soft surface to protect the ceramic and to verify proper spring bar extension before release.

Yes. Any strap with a 20 mm lug width and standard spring bars is dimensionally compatible with the CODE 11.59 26393QT.OO.A064KB.01. Milano Straps offers artisanal models in alligator, calf, rubber, and nylon made specifically for this width. Casati Milano also offers bespoke production with choice of leather, color, and stitching by appointment.

The lifespan of a leather strap depends on the quality of the material, frequency of use, and exposure to sweat and humidity. A first-grade alligator strap with vegetable tanning, under alternating daily use, has an average life of 18–36 months before showing signs of wear at the flex zones. Casati Milano straps are covered by an 18-month warranty against manufacturing defects. To extend their lifespan, it is advisable to rotate between at least two straps and avoid direct contact with water.
