Lot Essay

De Bethune's DB15 Perpetual Calendar Revolving Moon model contains several innovations never seen before in the field of fine watchmaking. Its movement by the way incorporates a variety of patents. Both from a technical and aesthetic point of view, one of the most interesting aspects is the highly unusual indication of the phases of the moon, a sphere in platinum and blued steel emerging from a subsidiary dial and rotating on its own axis. This allows showing the varying movements of this star in a very realistic manner, the representation of what can be observed in reality. Moreover the driving mechanism of the sphere is calculated so precisely that it will take over 120 years before it shifts. The entirely factory-made perpetual calendar mechanism provides the additional feature of a rapid date change via the winding crown, the leap years are indicated by the eclipse of a star represented on the moon.
