The particularity of the present watch is the positioning of the calendar system onto the balance cock as opposed to the indication on the dial by means of an additional hand as commonly found on pocket watches of the period.
An opening in the case back reveals the turning date ring, the date is indicated by a fleur-de-lys shaped pointer underneath the pendant. The work is of such high quality and so perfectly integrated in the case back that no difference is visible, underlining the craftsmanship of Geneva's casemakers of the period.
The watch is furthermore preserved in very good overall condition, the overall appeal further increased by the châtelaine.
The master watchmakers Jean-François Esquivillon and Jacques Dechoudens formed a partnership between around 1776 until the early 19th century and specialized in the manufacture of high quality watches including form watches.
