Light becomes part of the dial in the Code 11.59 by Audemars Piguet Grande Sonnerie Supersonnerie 26397BC.OO.D321CR.06. Its gradient-blue geometric shapes are created in plique-à-jour enamel, a technique without a metallic backing that allows light to pass through the translucent colour and reveals parts of the movement beneath.

This one-of-a-kind reference combines that decorative craft with Grande Sonnerie Supersonnerie, Petite Sonnerie and Minute Repeater functions. The dial balances its geometric pattern with luminescent 18-carat white gold hands and a blue inner bezel bearing white printed hour-markers.

An 18-carat white gold case frames the enamel, while a blue large-square-scale alligator strap continues the colour at the wrist. A matching white gold AP folding clasp completes the watch. The case incorporates a double-curved glareproofed sapphire crystal and a Supersonnerie soundboard caseback.
