Notes

After the French Revolution a new digital calendar was adopted, and the system of time measurement was completely changed. The day was divided into ten hours of 100 minutes each, and each minute was subdivided into 100 seconds. The dial of the present clock illustrates these innovations. The law introducing the changes was passed on 24 November 1793, and decimal hour measurement was suspended on 7 April 1795, meaning that these timepieces were produced during a period of only 18 months. The present watch features the single hand arrangement which Breguet so favored for his souscription watches a few years later.
