The movement is running smoothly. The dial shows minor scuffs, scratches, and some tarnishing towards the centre. The case has small scratches and abrasions, with the engine turning slightly worn at the edges, resulting in some loss of definition.

During the 1991 Art of Breguet auction, it was revealed that this watch was initially sold to Monsieur Rigaud on January 15, 1839, for 1000 Francs. However, it seems the watch was quickly reacquired, as Breguet sold it again to Monsieur Pierre Lalanne de Bayonne on September 17 of the following year. Later, it was once more reacquired and sold by Breguet to Henri Moser & Cie., who were Breguet’s agents in Moscow at that time.
