François-Paul Journe is probably the greatest watchmaker of the 21st century and will remain in the line of tradition of the very greatest, such as Christian Huygens, Abraham-Louis Breguet and Antide Janvier. It was in 1999 that he presented a collection of chronometers, or precision instruments, under the brand name F.P.Journe, and dazzled everyone from the outset by presenting two watches with genuine technical innovations: the Tourbillon Souverain with a remontoir winding-mechanism supplying the escapement with a constant force, and the resonance chronometer, the first wristwatch in the world based on the principle of the physical phenomenon of resonance (a phenomenon studied by Antide Janvier in clocks). The aim is to create new mechanisms only if that will improve the functioning of the watch, and this can be done by calling on all his abilities as a master watchmaker, his creative capacities, and his historical knowledge. Owning an F.P.Journe timepiece means acquiring a uniquely exclusive timekeeper with all the movements in solid 18 carat gold. It also means having a guarantee that all the movements are technically innovative and invented and produced (invenit et fecit) entirely by François-Paul Journe.
