This is the Part II of the video, showing the service and restoration of the antique mantel clock Medalle D'argent, made in France by Vincenti Co. The stamp on the clock indicates that the company won a silver medal ("medaille d'argent") at the 1855 Universal Exposition in Paris, which means the clock was made after 1855. The Vincenti Co. went out of business in 1870. The clock uses a patented Brocot suspension with a click spring, which started to be used since 1850. Based on above, the clock at work on my desk was built between 1865 and 1870. Another specific part of this clock is the mercury pendulum, invented by English clock master George Graham in 1721. Using a mercury allows compensate the physical changes of the pendulum rods due to the natural temperature fluctuations.
