History of Seth Thomas Ogee Mantel Clock

The ogee clock was a staple of American timekeeping in the mid-to-late 19th century. Developed primarily in Connecticut by clockmakers like Seth Thomas and Chauncey Jerome, these clocks were mass-produced using interchangeable parts, which revolutionized the industry. Their name comes from the 'S' shaped 'ogee' molding of the frame. This specific design allowed for a taller case that could accommodate the drop of weights or a pendulum while maintaining a slim profile for a mantel.
