Charles Edward Viner, active until around 1840, was renowned for his high quality clocks and watches. He was apprenticed in 1802 and a Liveryman in the Clockmaker's Company.
Viner is credited with the invention of a pump-winding system, an early form of keyless winding. The watch is wound by pulling and pushing a shaft located in the pendant. The repeating mechanism of the present watch is based on the same principle and activated by pulling out the shaft by means of the button in the band, turning it anti-clockwise and pushing it in.
