Seth Thomas Clock Company was founded in 1813 in Connecticut, United States so has a long history of producing high-quality timepieces.

The business began as a small clock-making workshop run by the eponymous founder and his family. The company grew over the years and by the mid-19th century, it had become one of the largest clock manufacturers in the world.

In the late 1800s, Seth Thomas Clock Company began production of ornate mantel clocks, which were often made of brass and featured intricate designs and engravings. These clocks were popular during the Victorian era and remain highly sought after by collectors.

During the 20th century, the company continued to produce a variety of clock models, including wall clocks, alarm clocks, and grandfather clocks. Many of these clocks were produced in classic styles that incorporated traditional design elements such as Roman numerals, pendulums, and chimes.

In the 1930s, more... Seth Thomas began producing electric clocks, which were more accurate and reliable than their mechanical counterparts. The company continued to innovate and in the 1950s, it began producing atomic clocks, which were the most accurate timepieces of their day.

In the late 1970s, Seth Thomas merged with General Time Corporation, another clock manufacturer, and the company was eventually sold to Talley Industries in 1985. Today, Seth Thomas clocks are highly collectible and are prized for their quality, craftsmanship, and history. less...
