Visually, this clock is such an early example from the 18th century in excellent condition, and technically, it needs cleaning, but complete and, in our opinion, completely original. The watch is an example of the finest Swiss watchmaking. Perrin Frères were known for their highly complicated and extremely fine pocket watches. They were building complex striking clocks as early as 1800.
