This enthusiast who played for Breguet a similar role as Graves with Patek Philippe 150 years later was probably the Count Fersen known as a fervent admirer of the Queen of France and the watch was named the Marie-Antoinette. It was completed in 1827, four years after the death of Abraham-Louis Breguet.
Breguet was the most skilful watchmaker of his time and the Marie-Antoinette could be used as a kind of prototype. On May 16 in Geneva, Christie's offers a high complication watch sold new in 1800 of our calendar (An VIII of the Republican calendar) to General Moreau. It is estimated CHF 600K, lot 123.
This pocket watch 55 mm in diameter has the serial number No. 217 of the brand. It is the only example beside the Marie-Antoinette to offer in the same case the perpetual motion and the equation of time.
The perpétuelle is a self winding mechanism with an oscillating weight offering 60 hours of autonomy from the effect of moderate movements of the user, with a protection against shocks on horseback. The equation of time is a correction of the difference between standard and solar times which can reach up to 16 minutes.
This piece does not include the technique of the tourbillon invented by Breguet in 1801. The steadiness is ensured by the échappement libre à ancre (lever escapement), another difficulty that only Breguet knew to overcome.
General Moreau died in the battle of Dresden in 1813. Breguet reacquired the 217 and modernized the dial before selling it in 1817 to Charles-Louis Havas, the financier who became famous for opening in Paris in 1832 the first ever newspaper translation business which became in 1835 his Havas Agency.
