Vintage Anniversary Torsion Pendulum Clock with Glass Dome
This is a mid-20th-century torsion pendulum clock, commonly known as an 'Anniversary Clock' because it is designed to run for a full year on a single winding. The item features a polished brass-finished metal construction with a circular base, supporting two vertical pillars that hold the movement and dial. The dial is ornate, featuring black Arabic numerals and delicate floral or scrolled decorative motifs between the numbers, set against a gold-tone face. Atop the movement housing are three decorative brass finials. The defining mechanical feature is the rotating four-ball torsion pendulum, which oscillates horizontally. The entire mechanism is encased in a tall, removable clear glass dome designed to protect the delicate suspension spring from dust and air currents. Inclusion of the original winding key is a significant plus for functionality. The condition appears fair to good; the brass shows some surface oxidation and minor tarnishing consistent with age, and the glass dome is intact without visible cracks. While no specific maker's mark is legible in the image, these were frequently produced by German manufacturers such as Haller, Kern, or Schatz during the 1950s-1970s.
