In pursuit of making thin wristwatches, an enamel dial was never done before by F.P.Journe as it requires more space and depth within a timepiece. . The vertical structure of the tourbillon on the F.P.Journe Tourbillon Souverain granted François-Paul Journe the opportunity to use, for the first time, an enamel dial. . The Grand Feu enamel subdial seen here is mounted directly onto the movement bridge, crafted from 18K rose Gold and finished with a “Clous de Paris” guilloché, a signature aesthetic of the 1991 prototype. . #fpjourne #fpjourneofficial #tourbillonsouverain #tourbillon #horology #watchmaking #watches
