Breguet #569 18K quarter repeater with early stemwind/set function sold to Count Campo Alegro in 1847 for 3,500 Francs.
The back of the three piece case is enamelled in cobalt blue and has a gold applied coat of arms of the Alegro family. The edge of the case has a repeating slide and a scale for fast/slow regulation without opening the back. The early white enamel snap-on fitted dial features roman numeral hours and a secret "Breguet" signature beneath the VI position. It has the original 18k gold Breguet hands. The bridge movement is 21 jewels and features a straight-line, counterpoised lever escapement, compensated balance with platinum timing screws and quarter repeating on gongs.
This watch incorporates the early stem-wind and stem-set function, apparantly invented by Breguet, consisting of a double-pinion on a winding stem, whereby one portion disengages when pulling out the stem and the other engages, allowing the watch to be set.
The dial is signed and the case is stamped in the typical Breguet manner with a B under the serial number and French 18K guarantee stamps. It also comes with a letter from Emmanuel Breguet which authenticates the watch. Dimension: 44 MM.
