1862 British antique decorative dial key-wound pocket watch, diameter 53mm, in good working order

We would like to introduce you to some antique British pocket watches.

This pocket watch from 1862 has a beautifully engraved metal dial and pure silver case.
This is a so-called "unnamed" pocket watch, without a manufacturer or brand name.
In the 19th century, Britain, known as the world's factory, was home to many such watchmakers, many of which are now defunct.
The mainspring is wound by key, and the time is set by inserting a key directly into the center of the hands and turning it.
It is unknown whether it has been overhauled, but the balance wheel is in good condition and ticks along smoothly.

We hope that this once-in-a-lifetime encounter will be a special one!
