Within its Geneva Watchmaking Workshops, the Maison perpetuates and brings these know-how to life, in particular through an enamel workshop and a training school. Van Cleef & Arpels perfects traditional methods such as plique-à-jour or grisaille enamel. This technique, a hallmark of the Pont des Amoureux collection, allows for striking chiaroscuro effects.

First developed in 16th-century France, the grisaille enamel technique uses two different shades to create chiaroscuro effects and a sense of perspective. Colored grisaille enamel follows the same process but with pastel tones. Adding depth or delicate beauty to the dials of the Pont des Amoureux collection, these hues recreate, in turns, the magic of a starry night and the dreamlike tones of every minute of the day.

This métier d'art allows light to pass through the enamel like stained glass. An open-worked gold structure filled with thin layers of enamel forms the motif. On the Lady Féerie watch, this technique gives the fairy’s wings a transparent effect, accentuating her airy silhouette.

Using the enamel decal technique, the story on the dial continues on the back of the watch. On the Lady Arpels Jour Nuit creation, the case is graced with a fairy in a dreamlike setting. To achieve this magical effect, the craftsman creates an enamel design on a steel plate, before stamping this motif onto the sapphire crystal that protects the oscillating weight.
