Oiling the Great Clock

In addition to inspecting all parts of the mechanism, the clockmakers oiled the clock and greased the auto-winder. Oiling and greasing the mechanism ensures the smooth running of the clock for the next six months. The auto-winder was installed in 1912 to assist with the winding process. The going train is still wound by hand, three times a week.


When the inspections and maintenance were complete, the Great Clock was started at the new 12 midnight. The clockmakers then had two hours to monitor the clock and make any adjustments necessary to make it accurate within one second. Fortunately on this occasion, no adjustments were needed and the dial lights were switched on at 2am on Sunday morning.
