Description
Oiling the balance wheel of a pocket watch. The balance wheel is a heavy ring fixed to the main spring. It is the oscillation of the wheel which marks the time. These oscillations may be speeded up or slowed down by altering the spring tension by means of the small lever right of centre. This fine watch was made in about 1860 by the London firm of Camerer Kuss & Co.
