The MasterGraff Perpetual Calendar is a Grand Complication skeleton watch that, like all Graff Diamonds timepieces, pushes the boundaries of horological innovation. Intricacy and transparency characterise the movement and the entire watch to ensure a powerful visual impact.
The skeletonised Calibre 7 allows the automatic winding system with micro-rotor to be clearly viewed. The dial alternates openwork and translucent windows to create an even more powerful aesthetic. Indications for the perpetual calendar with large date are displayed on discs created using an electroforming process for a skeletonised effect. Day and month are spelled out. At 6 o'clock, a one-minute tourbillon with three Icon-inspired spokes introduces a new design for Graff. This three-lobed motif is a signature of Graff Diamonds, and now part of its spectacular horological creations.
