Aaron Willard Jr. Presentation Banjo
This is an important example of a "patent" timepiece, a reference to the patented clock originally created by Simon Willard. Collectors refer to this as a banjo clock because of the shape of the case.
Three things make this an extremely rare clock. The clock is in original condition, including the reverse painted glasses. It has a rare alarm function. And it has a thermometer under the throat glass, very rare and desirable. One collector described it as a museum clock.
Mahogany case with carved gold gilt rope frames. Painted metal dial is signed "No 2447" and "A. Willard Jr., Boston". Lower glass shows a sunburst "Aurora" scene, a female goddess riding a chariot behind two white horses, surrounded by four women and a child blowing a horn. Brass hinged top door with a simple sprung metal catch. Lower door latch is engaged using the winding key. Can't tell if this originally had side rails, I didn't find any obvious holes.
8-day time and alarm movement is powered by two weights. Alarm bell is on top where a finial would be mounted. The alarm time is set by moving a third gold hand. Even the crank is very old, possibly original.
