This watch was sold to Madame la Maréchale de Lauriston on April 30, 1840, for the amount of 1 300 francs.


The watch employs a very unusual, apparently experimental balance: the top part is made of steel and is fused to the platinum bottom. Apparently, Breguet conceived a new type of bimetallic compensation and implemented it with this watch.


Léopold Sécheret, casemaker, entered his mark in Paris in May 1834. He was the casemaker Breguet Neveu most used.


Madame la Maréchale de Lauriston was the wife of Jacques Law, Marquis de Lauriston (1768-1828), Aide de camp to Napoléon Bonaparte in 1800 and 1805, Ambassador to Russia in 1811, and nominated Maréchal de France by Louis XVIII. He participated in the 1823 Spanish expedition.
