The case is classic round but with a twist – in a nod to its flagship model, the case middle is octagonal. The details become clearer when viewed from the side where you'll also discover that the upper part of the openworked lugs are attached to the extra-thin bezel while the lower part are melded with the caseback.
Perhaps more interesting is the anti-reflective sapphire that is vertically curved from ‘6’ to ‘12’ on the upper side, and domed on the lower side. This apparently enhances the visual appeal of the dial.
The Le Brassus manufacture has also fashioned its brand name on the dial using, for the first time, a technique known as galvanic growth, a form of micro-electronic that allows it to manipulate extremely thin layers of 24k gold with remarkable precision. The result is an attractive 3D signature, a small detail perhaps but one that demonstrates Audemars Piguet’s willingness to push design limits.
