The Seth Thomas “Sonora Chime” clock, introduced in the early 20th century, is a remarkable mantel clock that continues to captivate antique collectors today. This timepiece stands out as a popular choice within the Seth Thomas catalog due to its unique combination of style and functionality.
Typical case materials for the Sonora Chime include mahogany, walnut, or oak, with intricate marquetry designs adorning the front doors and sides. The clock’s cabinet is often decorated with delicate floral patterns or geometric motifs, reflecting the Art Nouveau aesthetic popular during its production era (approximately 1900-1930).
What makes the Seth Thomas Sonora Chime collectible goes beyond its beautiful design. This model was equipped with a unique chime mechanism that produced a rich, melodic sound, hence the name “Sonora.” The Westminster or Whittington chimes could be silenced by a switch, making it an appealing option for homes and offices alike. Notable features of this model include its eight-day movement, brass dial with Roman numerals, and finely crafted pendulum bob.

Very Rare Seth Thomas hanging Sonora Chime clock.
The movements, dial, and bells are just like those used in the more common shelf model Sonora Chimeclocks. The Seth Thomas time movement is the common No. 89, and the Sonora chimingunit is No. 90. This one is a 4 bell model. The mahogany case is 25 inches tall, it has the original 8 inch painted zinc dial with a little paint loss, andis signed “Seth Thomas Sonora Chime”. The case has a factory mark of “17”, which no doubt means the clock was made in 1917. The old brass pendulum bobhas the Seth Thomas circular etchings. There are wooden cutout side windows that allow the pure tones and rich melodies to escape the confinement of thecase. I spent more time than I should have, researching wall SonoraÕs, andcame up empty. I am sure there are some out there in private collections, but in all my years this is the only one I have seen. A tiny bit of information is in the NAWCC Bulletin of August 1978, Whole Number 195; and Ly-Seth Thomas page 206-211.
