    Description

    English Rare Verge with Differential Dial and Mock Pendulum, circa 1700
    Case: 56 mm outer sterling silver case, inscribed on the back "Revo J.A. to S.A", five joint hinge, plain inner case with split front bezel, glass bulls eye crystal
    Dial: champlevé silver with Roman hours, single gilt minute hand, inner and outer minute tracks, swirl leaf ornamentation, outer five minute numerals, gilt border
    Movement: fire gilt full plate, verge fusee, half open circular cock with mock pendulum bob, pierced tulip form pillars, blue steel disc regulator, worm and wheel set up between the plates
    Signed: movement and dial unsigned, case with partial hallmark

    This is a very rare and innovative timepiece. The center of the dial is a revolving disc marked with the hour numerals. As the watch runs, this disc revolves 13/12 of a full circle in an hour. A minute hand which is centrally placed, revolves once an hour and is thus always passing over the current hour numeral. This design is similar to a digital jump hour watch with the exception that the differential hour disc is always in motion.
