Secunda Sonata
A HARMONY OF COMPOSITION – THE SECUNDA SONATA BRINGS TOGETHER THE PHASES OF THE MOON AND THE CHIMING OF THE PASSING TIME
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.
The power reserve of the SECUNDA SONATA is 30 days.
SECUNDA SONATA has the following dimensions: height: 145 cm, width: 37 cm, depth: 18 cm.
