Antique American Marble Mantle Clock with Open Escapement – 8-Day Movement

This American antique marble mantel clock is a quintessential example of 19th-century horological craftsmanship. Likely produced during the "Golden Age" of American clockmaking (circa 1880–1890) by renowned manufacturers such as Ansonia or Seth Thomas, this piece features a rare and highly sought-after visible open escapement. This mechanical feature allows the movement's precision to be viewed directly from the front dial, making it a captivating conversation piece.

The clock is housed in a substantial, solid marble case with a rich natural sheen and intricate detailing. Its 8-day mechanical movement has been remarkably well-preserved, offering reliable timekeeping alongside a resonant chime that marks both the hour and half-hour.
