The present watch is a particularly fine example of the Zenith minute-repeating carillon clockwatch. This type of minute repeating Grande Sonnerie clock watch movement, with carillon on three gongs with three stacked hammers but without Petite Sonnerie, was usually commercialised by Zenith using the Cesar Racine patent.
