Monsieur Aufresne was a Breguet client who purchased at least 13 watches, most of them in 1807 and 1808. Two of them ended up in Polish hands, one becoming the property of Count Potocki, which suggests that Aufresne may have been a Breguet agent operating in Poland and Russia. For a biography of Breguet, see page 203. The next two watches, lots No. 112 and 113, are particularly representative of Breguet?s innovative genius for employing guilloché as the principal decorative element of his watches. These two watches were called "mon-tres médaillons" in Breguet catalogues of the period because of their dimensions, and were given cases of a "collier" form. The concentric circular pattern of the first one, and the stripe decoration of the other, are particularly interesting because Breguet was practically the only one to use them. Their back covers, protected by glass, have been preserved in al-most new condition. To our knowledge Breguet was the only one to protect the back covers of his medallion watches, which were exposed to wear, being suspended from a chain around the neck.
