The dial is the mechanism
The 15407 changes the usual Royal Oak decision by making the movement visible from the front. Instead of a single field of repeating squares, the openworked dial creates layers: bridges, wheels, apertures and markers sit inside the octagonal frame. The result is more dimensional than a closed dial, and it rewards a closer look. The frosted bezel and bracelet provide a bright, tactile perimeter so the open centre does not lose definition.
