    Tortoise shell, metal, glass, wood; casting, gilding

    Dial 29 cm


    Eight tune musical pipe organ and quarter chiming wall clock with bracket. The dial: black Arabic minute numerals and black Roman hour numerals. Fine regulation adjustment by turning a small winding square cut out in the numeral 12. Right faster, left slower; a pair of pierced and engraved brass hands. Two large winding squares for the spring powered going and striking trains are set to the left of the dial.

    The dial is mounted on engraved false plate depicting floral swags and musical instruments, visible through the lower half of the front door. Large brass rectangular movement is spring driven with verge escapement and silk suspension. Eight-day duration, striking the hours on a single bell, outside count wheel for the strike. The whole movement is mounted on the left side of a wooden seat board, which is why the winding squares in the dial are situated to the left side, thus making room for the massive brass double spring barrel fusee movement that powers the musical pipe organ. The fusee has a very large single winding square attached to a gearing that rotates a long steel rod. The rod turns large brass wheel connected to the wooden pin barrel and thus lifts fourteen brass valves at different intervals and releases the given amount of air from the bellows to the fourteen tin flutes for each single sound. An adjustable brass fly pinion controls the speed of the tunes. A decorative brass arm, connected to the back of the clock movement lifts automatically on the hour and releases a tune. The selection is mounted outside of the case. The case has a red tortoiseshell ground decorated and ornamented with chased bronze onlays.
