This highly ornate clock was designed in a style that is a blend of neoclassical and Baroque influences, characteristic of Ferdinand Barbedienne's work.

The base of the clock is crafted from onyx with hues of pink and cream, featuring a high degree of translucency that is typical of this luxurious material. The onyx portions are supported by a dark marble platform with a complex footprint, extending outwards at the bottom, providing a stable clock foundation.

The pedestal is elaborately detailed with gold or gilded bronze accents, reflecting the clock's 'Dore' (gilded) aspect. The columns of the pedestal are reminiscent of fluted Greek columns, topped with Corinthian capitals, a clear nod to classical architecture. These columns frame panels that are decorated with hand-painted scenes and intricate marquetry. The craftsmanship reflects a high level of detail and care in creating narrative or decorative scenes on these panels.

Rising above the pedestal is the clock itself, which appears spherical and is made of metal with a gold finish. The sphere is decorated with a starburst pattern in royal blue enamel, punctuated by golden stars, creating a striking contrast and adding to the opulence of the piece.

The top of the sphere is adorned with an elaborate gilded crown-like feature, adding to the verticality and grandeur of the piece. This element may house the bell or chimes traditionally found in clocks of this period.

Overall, the clock is a testament to the luxurious and grand designs popular in the 19th century among the affluent. Ferdinand Barbedienne was renowned for creating such high-end decorative art pieces. The combination of precious materials, like onyx and gilded bronze, along with the high level of craftsmanship, suggests this clock would have been a centerpiece in a grand setting meant to impress and denote status.
