Dumonchel a Paris, a rare table regulator with unusual escapement and perpetual calendar, the large four glass case with gilt brass frames and molded marble base and top, four white enamel dials with gilt, engraved mask, the upper displaying dead seconds above roman numeral hours, the lower showing the date, and two small subsidiary dials displaying day and month, 8 day two train movement with break arch plates and Brocot escapement, the pallet with auxiliary pivoted lever driving a seconds wheel, the wheel advanced at alternate vibrations, and so enabling a dead seconds display from a half seconds pendulum, the compensated pendulum with zinc and steel rods, the bob with scale indicating change in length
CONDITION: case dirty, frames tarnished and lacking gilding, marble with minor chips and bruises, front glass with chip at upper right, rear glass with minor chips at top edge, dial mask with minor dirt, month dial with two faint hairlines, seconds hand with missing tail, other hands good, movement ticks and strikes, calendar functions operating, will need adjustment, pendulum with marks, scratches, later fasteners, and open holes, scale with loss to paint. The method used to adapt a half seconds movement to display full seconds is quite unusual. The auxiliary attachment to a conventional Brocot escapement and the addition of a wheel independent of the time train allows the display of dead seconds in the manner of the coup perdu escapement. In addition, this arrangement allows for the impulsing of the pendulum on each vibration, as opposed to the coup perdu, which impulses on alternate vibrations.
