This pendulum clock is also an extremely accurate timepiece, maintaining a maximum accuracy deviation of one to two seconds per month. A weight running down the side allows a power reserve of 30 days. The fine gear wheel teeth and the use of ball or jewel bearings for all turning parts ensure a service life lasting for many generations. The slight changes in the length of the Super Invar pendulum rod, which are caused by temperature, are counterbalanced by a precisely calculated, freely swinging compensation tube. Three bevelled glass panes allow a fascinating view of some of the Classica Secunda 1985’s internal secrets. An additional window in the top allows light to illuminate the movement from above. The clock’s plates, pillars, pallet bridges and cocks, gear wheels, guide rollers and chatons are milled and turned in small-batch series in the manufacture. Many components are finished by hand and decorated with gold-plating. The winding crank, fine adjustment weights and additional accessories are hidden in a compartment in the bottom of the case. The attention to detail that goes into the manufacture of the Classica Secunda 1985 makes it a functional yet beautiful object, which will be treasured for a very long time.
