F.P. Journe’s extraordinary grande sonnerie and minute repeating watch guarantees both functionality and security - protected by no fewer than ten patents

F.P. Journe presents the book of the Grande Sonnerie watch. It revisits the centuries-long history of striking watches as well as that of the outstanding Sonnerie Souveraine, of which only 4 examples are produced by the manufacture each year.
The Grande Sonnerie and Répétition Minutes wristwatch is one of the most complex horological creations. For the first time in history, a grand strike clock watch offers true comfort and total security. 35 040 automatic chimes and 332 880 hammer strikes rings the time. The Sonnerie Souveraine F.P. Journe sets a clear precedent, embodying its creator’s mechanical vision in its musical expression of time. It ensures that his name will go down in history as having enriched horology and given life to new ideas that enhance the science of time measurement.
This watch is protected by ten patents attesting to the "Invenit*" of this work of Art, and six years of research and development to the "Fecit*" in the Manufacture’s motto.
This magnificent 90-page book, in three parts, is illustrated with many original photographs. It is written by Jean-Claude Sabrier for the historical section and Vincent Daveau for the history of the Sonnerie Souveraine. The final section describes the watch’s 10 patents, the details of its functions, its exclusive security systems, and the art of sublimating mechanism in music.
In addition, the book in its luxury edition features an audio system that makes it possible to hear this extraordinary watch strike the hours, the quarters and the minutes. For sale in the F.P. Journe Boutiques.
