Accompanied by Patek Philippe Extract from the Archives confirming production of the present watch in 1912 and its subsequent sale on 17 January 1916.
It is thought that only five examples of a carillon repeating watch by Patek Philippe with no further complications are known to this day.
The carillon repeating mechanism is more complicated than the better known quarter or minute repeating function and is more commonly found in clock watches. It features three or four gongs instead of only two. The quarter hours of the present watch are stroke on three hammers onto three gongs.
