Signed on the movement. In very good condition. Diam. 56 mm. This watch employs three of Potter's patents, the details of which are engraved on the bridges. The plate design, which is virtual machining from the solid, was patented on January 4, 1876, the escapement and presumably the great wheel design, on October 11, 1875. Albert Potter's work is not only rare, but always of top quality and completely original design. Such chronometers were usually manufactured in Geneva for the American market. This watch, signed by Henri Kreig, Paris, undoubtedly made for the French market, is maybe unique not to be signed by the name of Potter, Henri Kraig is not recorded in Paris as a chronometer maker nor a dealer.
