Charles Viner was apprenticed to Thomas Savage in 1802. Although he did not become Free of the Clockmakers’ Company until 1813, it would appear that, by this time, he had already set up his own business. Combining the features of alarm, repetition, and duplex escapement, the present watch illustrates the high quality and often complex nature of Viner’s production. The screw type bi metallic balance has echoes of Pennington’s last form, and the alarm and repetition is to a gong; a relatively early example of this type.
