Notes

In Breguet's workbooks escapements are rarely specifi ed and the present watch is one of only a handful to be described as ''répétition garde-temps échappement isolé''. Breguet must have considered this watch to have sufficient merit to be called ''garde-temps'' a description reserved only for the fi nest timekeepers. Later the term ?garde-temps? applied only to watches with chronometer escapements and is usually only applicable to those. The movement of No. 23 is of the new caliber started in 1799 and is called the Lépine caliber after the the famous Parisian watchmaker Jean- Antoine Lépine. This watch is illustrated in ''The Art of Breguet'', George Daniels, 1975, p. 154.
