Evolution of horological mode, as seen by J.D. Rubeli, designer with the firm of Patek Philippe. The first sketches correspondent to the changes of the past five years - from the traditional round shape to the new “widened soft look” which makes its appearance at the Montres et Bijoux Salon this year. The last shape, oval, still has a large question mark hanging over it, but is most strongly tipped to succeed as the dominant watch shape of the future.
