Notes

The movement of this quality watch was probably made in the Vallée de Joux, in a workshop of the level of those of:
• Louis-Elisée Piguet (1836-1924), Le Brassus (Vallée de Joux).
• Emile-Victorin Piguet (1850-1937), Le Sentier (Vallée de Joux).
Main plate, under the dial, scratched with an etching needle “2422”.
