French wall-mounted regulator, 1920s

An observatory regulator made by the French firm Brillié, mounted on grey and white marble. The Brillié company was founded by Lucien Brillié and Charles Vigreux in 1897 near Paris, and rose to become the pre-eminent French electrical timekeeping company of their day, supplying the Paris Observatory and French national time service. Many of their clocks were sold with a compensated pendulum, and the present one is from Brillié but not the original one supplied.
