The Grand Regulator with manual winding features a sophisticated 3-D dial design with floating subdials and minute display.
Flying Grand Regulator
The dial design of this timepiece is characterized by several levels: While the lower one is decorated with guilloche pattern, a second level was designed with the scale for the central minute display. The dial is topped off by the funnel-like hour and second displays floating above the minute scale.
