clocks had been relatively expensive, both Willard brothers strove to compact the traditional 18th century British type of longcase clock. They simplified its action-mechanism and, for casing, they used specifically tailored wooden frames—which were uncomplicated for either manufacturing or assembling. Their new smaller models were relatively economic. Therefore, sales rose quickly, and the Willard brothers supplied clocks to both public and domestic consumers. Aaron Willard's models were: Tall clock (Grandfather-Clock) Massachusetts Shelf clock Willard Patent Timepiece (Banjo-Clock) Gallery Clock Regulator clock 30-hour wall clock (Grafton timepiece) On every unit, Aaron Willard spelled his signature out, over either the dial or the glass-panel. Tall Clock (Grandfather-Clock) Aaron Willard began manufacturing and commercializing traditional tall case clocks (referred to as longcase clocks outside of the US). These clocks, often called Grandfather clocks today, generally stood about 7 1/2 to 8 feet tall . Although some other clockmakers produced wooden movement clocks, Willard made only clocks with brass movements. His tall case clocks were always of eight-day duration (other than extremely rare extended running clocks). The case Like Simon's, Aaron's clocks adopted a distinguishing feature early: since 1790, about their cases where, up over the dial, the case-door delineated a half circle which echoed the dial. The clocks' tops were adorned with a series of wooden curly arrangements called Whales-Tails. Later on, these ringlets evolved, and they finished extra-stretched and artistically riddled too. Many elements of brass—which were usually imported—sprinkled all case's woodwork. Particularly, Aaron's clocks had three spherical finials on top. However, the case presented a spate of other small brassy touches around, depending on the model. The case's door was secured by means of an iron lock. Faces The clock dials (faces) were painted iron. They were produced with varying complexity, in accord with the price of the model. For the economical, it was relatively unadorned. For the most expensive types, the dial featured artistic paintings from recognized Bostonian artists. Aaron Willard increased the value of his clocks by adding features to the dials. Most had a revolving calendar wheel, indicating the date. Many incorporated a revolving moon disc at the top of the dial for indicating the phases of the moon. In rare instances, a "rocking ship" dial was used. These were produced in Boston and are highly desirable to collectors. They are fitted with a small depiction of a sailing ship that rocks back and forth in the arch
