THE ART OF GUILLOCHE
Guilloché (also called engine-turning) is a decorating technique in which intricate geometric patterns are engraved onto dials and, sometimes, cases. Lines are etched into the part via a hand-operated lathe, either in straight lines or in circles. The difficulty of this process does not only rely on the precision required but also on the right and continuous pressure of the hand in order to get a perfectly regular pattern. Most of the current Master-Guillocheurs, learned through an apprenticeship with another Master as this art is not taught anymore in watchmaking schools.
CZAPEK GUILLOCHE RICOCHET ®
The Quai des Bergues “Sea Salt Grey”
The Czapek exclusive “Ricochet” Guilloché pattern takes the inspiration from an ancient design created by Francois Czapek in the 1850s. Its main characteristic and unique feature is the presence of a double focal point, unlike traditional Guilloché patterns with only one focal point at the centre of the dial. The two focal points, corresponding to the two iconic Czapek subdials – indicating small seconds and power reserve – create a fascinating “wave interferences” in the dial, hence the name: Guilloché Ricochet ®.

CZAPEK’S GUILLOCHE RESONANCE
Called Résonance, this special guilloché is derived from the Ricochet ® pattern of the Quai des Bergues collection: concentric circles originating from the two sub dials at 3 and 9 o’clock intersect and form bas-relief squares. But this time, the lines are much deeper and wider, creating a sporty guilloché, tnever made in watchmakingunique in watchmaking. It took our Master Guillocheur a lot of effort and time to get the right result but the biggest challenge was elsewhere: in order to enhance the light effects, we decided to add to this pattern a curvy, “bombé” shape. So, to avoid any deformation or distorted lines, we had to find a special allow, replacing the too soft 18 carat gold used traditionally. This is why all our dials featuring the “Résonance” guilloché are made out of our special 401 alloy, a combination of 55% gold completed by a mixture of platinum, palladium and silver.

THE ART OF ENAMEL
The Czapek “Grand Feu” enamel dial is one of the most difficult technique of the art of watches decorating which offers as well the highest durability. The master artisan of our Manufacturing Partner Donze Cadrans in Le Locle, does not paint the motif directly on the watch but applies more oxides on the dial in gold. Then, the enameler moves the dial into fire (800-900° C) several times to allow motif and colors appear gradually. The “Grand Feu” enamel sets unalterable and refined decoration… including a secret signature in the case of Czapek.

THE FLINQUE TECHNIQUE
The Quai des Bergues Sapphir Blue S
“Flinqué” is a technique combining the stamping of geometric patterns, which have been initially engraved on a die using the guilloché technique, with enamelling. The guilloché pattern used with the original “flinqué” technique was so recognizable that it gave it its name. Nowadays any pattern can be used in a “flinqué” dial
Czapek had its partner Metalem recreate its own “Ricochet ®” design – a motif inspired by the ripples of a stone skipped on a lake – on a stamping tool. Once the décor is stamped on a silver plate, an intense ‘moiré’ enamel is applied by another Czapek partner, Donzé Cadran. It is then finally fired in a kiln to harden the enamel. The process is repeated several times until the right hue is achieved.
