In this article, we dive into the story, features, design, and collectible value of Seth Thomas Grandfather Clocks.
1. Who Was Seth Thomas?
Seth Thomas (1785–1859) was a pioneering American clockmaker and entrepreneur. In 1813, he founded his clock company in Plymouth Hollow, Connecticut, which later became the town of Thomaston in his honor. Over time, Seth Thomas Clocks became a household name, known for their precision and aesthetic appeal.
The company produced a variety of clocks—from simple mantel clocks to elaborately carved grandfather clocks. Even long after Seth Thomas passed away, the company continued producing clocks under his name, solidifying a legacy that still ticks today.
2. The Rise of Seth Thomas Grandfather Clocks
Although Seth Thomas is perhaps best known for his mantel and wall clocks, his company also produced stunning longcase or grandfather clocks—especially during the late 19th and early 20th centuries. These clocks were built to last generations, both in function and beauty.
A typical Seth Thomas grandfather clock features:
- A tall, elegant case made from high-quality woods like mahogany, walnut, or oak.
- A weight-driven mechanical movement, ensuring consistent timekeeping.
- A long pendulum that swings rhythmically in harmony with the chimes.
- A face adorned with Roman numerals, moon phases, or painted dials.
3. Features of Seth Thomas Grandfather Clocks
Here are the notable elements that set Seth Thomas grandfather clocks apart:
A. Mechanical Movement
Most of these clocks feature an 8-day weight-driven movement, meaning they require winding once a week. The movement was often signed with the Seth Thomas name or initials like "ST", a signature of authenticity.
B. Striking and Chimes
These clocks often include hourly striking and even quarter-hour chimes. Some models played Westminster chimes, offering a rich, melodic tone that filled the home with nostalgic charm.
C. Pendulum and Weights
Seth Thomas clocks use a long pendulum and brass weights, suspended inside the tall cabinet. The pendulum’s motion regulates the time, while the descending weights power the movement and chimes.
D. Moon Dial
Many models include a moon phase dial—a rotating disc that tracks the lunar cycle, an elegant and functional addition.
4. Cabinet Design and Styles
Seth Thomas clocks embraced both traditional and decorative styles, making them fit into both period and contemporary homes. Cabinet features often include:
- Arched bonnet tops with finials.
- Scrolled woodwork and carvings.
- Glass panels to showcase the pendulum and weights.
- Brass or silver-plated dials with intricate designs.
Some models are simpler and more Colonial in appearance, while others are ornately Victorian.
5. Collectibility and Value
Seth Thomas grandfather clocks are highly collectible, especially:
- Early models from the mid-1800s.
