Audemars Piguet
CODE 11.59 26393NB.OO.A002KB.01— lug 20mm

The Audemars Piguet CODE 11.59 26393NB.OO.A002KB.01 is fitted with a 20mm lug width. This measurement is taken with a caliper positioned between the two lugs of the case, measuring the inner distance. It is a standard width that ensures broad availability of compatible straps, both artisanal and mass-produced.

Given the black ceramic and white gold case, a glossy black alligator strap represents the most coherent choice: it reflects the ceramic surface and adds texture without competing with the case. Alternatively, midnight blue or anthracite gray smooth calf offers a softer yet equally refined aesthetic. Black vulcanized rubber is ideal for sports use, highlighting the chronograph nature of the AP 4401 caliber.

The strap is removed using a spring bar tool with the appropriate forked-tip instrument. It is essential to work carefully on the black ceramic surfaces, which are particularly prone to scratching, protecting the case during the procedure. It is recommended to entrust the operation to a qualified watchmaker or the Casati Milano atelier to preserve the integrity of the finish and lugs.

Yes, the standard 20mm format allows full compatibility with high-quality aftermarket straps. Milano Straps offers a selection of artisanal straps in alligator, calf, and rubber, made with carefully selected materials, compatible with the CODE 11.59 lugs. For a fully customized solution—with choice of leather, color, stitching, and buckle—the Casati Milano atelier offers a bespoke service.

The lifespan of a leather strap depends on the quality of the material, frequency of use, and exposure to sweat and humidity. A high-end artisanal strap in alligator or calf, with alternating use and proper maintenance—natural drying, away from direct heat sources—can last from 2 to 5 years while developing a desirable patina. Casati Milano offers an 18-month warranty against manufacturing defects on all straps made in the Milan atelier.
