Notes

This watch is evocative of a brief and turbulent period in French history when the new Republic decreed the use of decimal time. After the Revolution, a new digital system was adopted. The day was divided into ten hours of 100 minutes each, each minute being subdivided into 100 seconds. Thus, for example, 12:30 PM was 5:20:83.3 in decimal time. The decimalization of time was introduced on November 24, 1793. The new division of time proved impossible to enforce, and was suspended on April 7, 1795. Thus, there was a period of less than 18 months during which these timepieces were produced, which explains why they are so rare. See: ?Revolutionary Time?, Vox Magazine, 2004
