The Cintrée Curvex, like all Franck Muller creations, has its own story. The project was to make a very complicated watch within totally new contours.
Franck Muller devised a completely new watch-case: all research was based on the discovery of a single spherical point at which the three axes of the watch's curves had to meet.
Scientific calculations were made based, among others, on perfect balance, which resulted in this famous three-dimensional watch-case, so characteristic of the Franck Muller style.
The achievement of this creation is the curvature at 3 o'clock, 9 o'clock, 6 o'clock and 12 o'clock. For a better understanding of this aspect, it should be noted that the contours of a classic tonneau watch-case are less elaborate in design and are curved only at 6 and 12 o'clock.
The three curves of the Cintrée Curvex watch are in perfect balance. The manufacturing procedure is Franck Muller exclusivity. The most sophisticated machines are needed to produce it, as not only the watch-case but also the back, dial, hands and glass are shaped.
