Viennese picture clocks are a specialty of the Biedermeier period. They impress with their masterfully painted, detailed sights in which the dial is skillfully integrated. Other than the French version Viennese picture clocks were painted on metal, not on canvas. This resulted in particularly intense colors and extreme durability of the painting and also offered the possibility of integrating holes on the front for winding. In the French versions the comparably unstable canvas of the paintings had to be swung open, in order to wind the movement, which was attached to the back panel. Some Viennese picture clocks are also equipped with automatons and/or musical mechanisms.
