Albert H. Potter & Co., Chicago (U.S.A.), made circa 1880, timed by James Murset. Rare keyless pocket chronometer workshop case. Three piece, massive with glazed back and milled bezels. White enamel with Arabic numerals and sunk subsidiary seconds. Blued steel Breguet hands. Notes 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, 1875, the escapement and presumably the great wheel design, on 11 October, 1875. Albert Potter's work is not only rare, but always of top quality and completely original design.
