Notes

Décor of pearl-set en épargne and painted enamel on flinqué enamel under fondant The artisans who made these case-back and cover had to surmount many difficulties, among them the preparation of the background representing the sky, partially guilloché (engine-turned) or engraved in taille-douce. The decoration en épargne (the trees and vegetation), later set with half-pearls, had to be completed before the enamelling process began. Here various techniques were used: painted enamel, translucent enamel, and a final layer of flux (fondant in French). The setting of the many different-sized pearls would have been an exacting task: certain pearls were glued and them mock setting prongs are added. This type of workmanship is characteristic of Jean-Louis Richter (1766-1841), who is known for his signed snuff-boxes, among other things. For a perfect example of this type of work, see: Antiquorum, Geneva, auction, October 2002, lot 42, sold for the amount of CHF 465 500.-; a pair of mirror-images pocket watches, signed by Ilbery, London, made for the Chinese market, kept today in the Patek Philippe Museum, Geneva (Inv. S-571 a+b). Bibliography Tellier, Arnaud, & Didier, Mélanie, Le Miroir de la séduction, Prestigieuses paires de montres « chinoises » ??
