Jean-François Cronier was apprenticed to Robert Robin (1741 -1799) one of the most brilliant French clockmakers. He then worked with his father Jean-Baptiste-François Cronier at Quai de la Mégisserie, Paris and was made Master in 1787. His father had been made Master in 1781. At this time, Jean-François was known as Cronier Jeune, but after his father's death in 1800 he was called Cronier l'aîné. In 1806 he moved to Place des Trois Maries where he worked until 1820.


Gobin Etienne, known as Dubuisson, worked at Sevres as a flower painter before specialising in watch cases and clock dials, he is recorded as working at various addresses in Paris. 


The remontoire, as used on this regulator, is an ingenious device for overcoming the variable driving force provided by spring driven clocks, depending on whether they are fully wound or almost run down. Variation in driving power adversely affects the timekeeping of a spring-driven clock; weight-driven clocks do not suffer in this way and so the remontoire is used to convert a spring driven mantel clock into a weight-driven clock. This is accomplished by using the clock's mainsprings to rewind at frequent intervals, a small weight which acts directly on the escapement. In this way the force of the mainspring has no direct impact on the escapement and so cannot influence the timekeeping.
