Enamelled copper dial dating from around 1825. (A)
Additional Info:
As this movement has been modified, it has a number code instead of the usual Vulliamy letter code. Such conversions and refurbishments of older movements were quite usual for clients wanting to update earlier movements either concerning the mechanical, the aesthetic aspects or both (as done in this movement) instead of buying a new watch (A). Also Abraham – Louis Breguet is known to have made such conversions of movements originally made by Ferdinand Berthoud.
