Museum piece
This anniversary clock from the 1970s has a black dial with applied brass-coloured Arabic numerals and three red roses as floral decoration.
The movement stands on two black columns, also decorated with roses. Brass-coloured ornaments and the four-ball torsion pendulum complete the design.
The round base is finished in black lacquer and edged with brass-coloured rings. A transparent acrylic dome protects the clock.
The anniversary clock has a mechanical Haller movement with a torsion pendulum. The anchor and the dial mounting are made of plastic.
The idea of the anniversary clock goes back to Johann Anton Harder. Together with other clockmakers, he developed the foundations of this technology in the late 19th century. Its distinctive feature is the slowly rotating torsion pendulum, which allows the clock to run for a long period between windings.

Simonswald · Black Forest – Baden-Württemberg · Germany
The history of the Haller name and family is closely linked to the clockmaking tradition of the Black Forest. Over the generations, several clockmaking businesses bearing the Haller name were established. The Haller Uhrenfabrik GmbH in Simonswald is among the most prominent of the companies still operating today.
Its history began in 1874, when Philipp Haller started making wooden clocks in St. Georgen. His grandson Siegfried Haller continued the family business and developed its mechanical clock production. In 1953, limited space at the original site led the company to move production to Simonswald. Martin Haller has managed the Haller Uhrenfabrik in its third generation since 2005.
A major milestone came in 1974, when series production of electronically controlled anniversary clocks began under Siegfried Haller Sr. The company also developed a radio-controlled anniversary clock and the patented Haller torsion-pendulum movement without a suspension spring. Today, Haller is especially known for mechanical anniversary clocks, including models with four slowly revolving balls. The range also includes other mechanical pendulum and mantel clocks.
Haller family businesses also shaped the clock industry in Schwenningen. Thomas Haller developed the business founded by his grandfather into a clockmaking company. On 1 April 1900, Thomas Haller AG joined forces with Junghans. After that collaboration ended, Thomas Haller continued to run the business independently. His son Thomas Ernst founded a separate clock factory in Schwenningen, Thomas Ernst Haller AG. Its founding date is given as 24 November 1902, while a biographical source dates it to 1903. In April 1928, Kienzle AG acquired Thomas Ernst Haller AG.
