Featuring a two-tone case, the Audemars Piguet Code 11.59 Tourbillon Openworked Watch highlights the piece's intricate construction. Its thin bezel, lugs, and case back on the 41 mm case are made in 18-carat white gold, while 18-carat pink gold on the octagonal middle case offers an elegant contrast. The openworked movement is hand-finished in varying shades of grey and encased by a tonal inner bezel. Hands crafted from 18-carat pink gold complete the dial and are set below a double curved sapphire crystal. The watch is finished with a grey rubber-coated strap with a white gold AP folding clasp.
