Hi KM,

Thank you for contacting Mearto with your appraisal inquiry.
This is a banjo clock, a type of wall clock that originated in the United States around 1800, and it's named for its shape, which resembles a banjo. It typically features a round dial at the top, a long, narrow trunk, and a wider rectangular base, often with decorative elements and reverse-painted glass panels.
While signed American banjo clocks can bring five and six figures if made by some of the most important makers, this appears to be a later Continental/European example,
Based on the photos and information provided, and subject to examination, this is:

A Victorian brass mounted and inlaid walnut banjo clock
Probably European, mid 19th Century
The circular head with acorn finial and circular brass-mounted hinged glass door opening to a white enamel dial with Arabic numeral chapter rings, flaring trapezoidal neck with glass panel and C-scroll supports, over a box base with eglomise (reverse-painted) panel depicting boats on the water.
12-1/2 inches high
CONDITION: Not in working condition, with some losses to eglomise panel and cracking to the face.
PROVENANCE: Inherited
$75-100*
