Audemars Piguet
CODE 11.59 15210BC.OO.A021CR.01— lug 18mm

The Audemars Piguet CODE 11.59 15210BC.OO.A021CR.01 is fitted with an 18 mm lug width. To verify this, measure with a caliper the internal distance between the two lugs at the case attachment point: the result will be 18 mm, a critical measurement for selecting a replacement strap that will fit properly.

For the CODE 11.59 in white gold, a polished black or midnight blue mississippiensis alligator strap represents the most coherent choice with the haute horlogerie register of the piece. The fine grain enhances the luminosity of the white gold. Alternatively, a box-calf leather in bordeaux or chocolate brown offers daily versatility while developing a personal patina over time.

Changing the strap on the CODE 11.59 requires a dedicated lever tool—the so-called spring bar tool—to be inserted into the hole on the lug to compress the spring bars and release the strap. This is a delicate operation on a white gold case: it is advisable to entrust the task to a qualified watchmaker or the Casati Milano atelier to avoid scratches on the finished surfaces.

Yes, quality aftermarket straps compatible with the CODE 11.59 15210BC.OO.A021CR.01 exist, provided they have an 18 mm lug width and adequate length (typically 75/115 mm or 70/115 mm). Milano Straps offers a selection of 18 mm straps in leather, alligator, and rubber crafted by hand, compatible with this reference.

The lifespan of a leather strap depends on the quality of the hide, frequency of use, and care. A high-end alligator or calf leather strap, worn in rotation and kept away from excessive sweat and water, can last from 2 to 5 years while maintaining optimal aesthetic quality. Casati Milano guarantees its 18 mm straps for 18 months against manufacturing defects.
