Guillaume Bouvier is recorded as working in Paris circa 1740, being one of a family specialising in the enamelling of watch cases and working in both France and Switzerland. A small group of watch cases bearing his signature are recorded and at least one signed plaque (see Sotheby's London, 19th March 1973, lot 268). It is usual for this technique of overlaying gold on enamel to be attnbuted to the Fromery workshops in Berlin, but the existance of many 'German enamel boxes with French mounts would indicate that there was a flourishing production in Paris as well. This particular example is of exceptional quality and in outstanding condition.
