The first pocket watches also included a protective cover that prevented the face from becoming scratched or shattered.
The chains and covers were usually decorated with either silver or coloured enamel.
Unlike regular watches, which have bands and are made to be strapped to the wrist, the pocket watch is protected from the elements by the clothing of the wearer.
Pocket watches date back to a time before wrist watches and they were even considered the most common type of timepiece until just after World War I when wrist watches became more popular.
