Jacques Coulin & Amy Bry, Geneva Jacques Coulin (1744-1812), Amy Bry (1750-1830) and Jean Flournoy (1727-1811) were associates in Geneva between 1782 to 1799.
This watch is fitted with an extra flat movement, the calibre with going barrel, directly derived from the works of Jean-Antoine Lépine (1720-1814), of which various examples are known (with cylinder or virgule escapement) made circa 1785-1795 by himself and other Parisian watchmakers such as André Hessen (1775-?), Dieudonné Kinable († 1815), Jean Gregson (1776-1790), Gustave Adolphe Adamson (c.1747-aft.1813), Jean-Hilaire Bassereau (1743-1806), etc. This kind of calibre was developing at the same time in Geneva. This achievement allows the production of very elegant watches whose cases are built with invisible hinges. If these watches, in the latest fashion, are very popular with the aristocratic clientele of the time, they are also appreciated in the export markets like China.
