In addition to its pleasant chime, the clock also has a handpainted moon phase display that lends a special appeal to the silver-plated dial. The combination of these two functions brings together visual beauty and acoustic splendour. As is customary with the precision pendulum clocks from Erwin Sattler, the pendulum of the Secunda Sonata is equipped with temperature and air-pressure compensation.
The gold-plated gear train, with a 30-day power reserve, is fully fitted with ball bearings and jewel bearings, while the classic Graham escapement is embellished with agate pallets. This exclusive ensemble is housed in a fine, contemporary case finished with metal inlays and a macassar cassette in the back.
