The Senator Excellence Perpetual Calendar - Limited Edition is a combination of traditional arts and innovative design. Skeletonizing, the cutting of delicate openings in individual components, has long been a fixture of the repertoire of a master watchmaker. Now Glashütte Original has made use of this technique to implement a fresh, modern design. Finely cut out from within the generous dimensions of the matte grey dial ring are the Panorama Date, moon phase, weekday, month and leap year displays, each accented discreetly with a stepped frame.
The central cut-out shifts the centre of attention to the technical aspects of the galvanic grey module cover plate, whose openings reveal the interplay of the calendar discs. An elaborate guilloche decoration adorns the movement's cover plate, its sweeping lines broken only by individual red jewels. The guilloche decoration is crafted by hand in the watchmaker's own dial manufactory in Pforzheim. In the process, traditional guilloche patterning tools are used to incise finely drawn geometric figures in the dial. Depending on how the light falls on the dial, the shimmering pattern takes on a very different appearance.
