The carved gilded rosette is mounted as a central decoration. The two train month going movement is of unusual construction, a brass weight is used for the going. A very well executed pin wheel escapement maintaining power and a separately suspended massive five rod semi-compensated pendulum. The strike is powered by a spring barrel and gives a quarter strike on two bells and the hours on a single bell.
Another unusual, but fine feature is the repeat on request which is activated by the means of a pull cord, the strike is released and sounds the last hour on a single bell, and ting tang on two bells for the last quarter.
All the steel and wheel work is very well executed. The back plate is also fully signed and engraved Jaquet Droz à La Chaux de Fonds.
