The Perigraph follows the MeisterSinger principle of clear circular arrangement. The date is not displayed in a window, but on the open date disk at 12 o’clock, making the Perigraph particularly reminiscent of classical analog instruments. This impression is additionally reinforced in the bronze version, thus creating the image of noble commitment to scientific traditions. The reverse side of the Perigraph features a sixfold screwed stainless steel back with an exhibition window that provides an excellent view of the Swiss automatic movement.
