Audemars Piguet
CODE 11.59 26439NB.OO.A346KB.01— lug 20mm

The CODE 11.59 ref. 26439NB.OO.A346KB.01 comes with 20 mm lugs. This measurement refers to the internal distance between the two lugs of the case on the hour side, and is the determining parameter for choosing a compatible strap. It is advisable to verify it with a digital caliper before purchasing.

For the black ceramic and white gold case of this reference, polished black alligator or matte night blue alligator represent the most coherent choices. Black box calf is a sartorial alternative that develops patina over time. For sports use, black vulcanized rubber maintains chromatic coherence with the ceramic while guaranteeing resistance and comfort.

The strap is removed using a fine-tipped spring bar tool or a springbar tool, acting on the spring bars that secure the strap to the case lugs. It is recommended to work on a soft surface to avoid scratching the ceramic and to use a quality tool to avoid deforming the bars. If in doubt, it is best to consult a watchmaker or the Casati Milano atelier.

Yes, all straps with 20 mm lugs and standard spring bars are technically compatible. Milano Straps offers a selection of artisanal 20 mm straps made with selected leathers and sartorial finishes, designed to enhance high-end watches like this Audemars Piguet reference. You can view the complete collection on the dedicated 20mm strap page.

The lifespan of a leather strap depends on the material, frequency of use, and care. A quality alligator strap, used in rotation with other straps and kept away from excessive sweat and water, maintains aesthetic and structural integrity for 3-5 years. Casati Milano straps are covered by an 18-month warranty against manufacturing defects and are made with selected tanned leathers that guarantee greater resistance over time compared to standard straps.
