INSIGHT

With its exquisitely enamel-adorned balloon, L’Epée 1839 once again ventures boldly into new artistic territory. Enameling is one of the oldest and most revered decorative arts in watchmaking, passed down through generations of highly skilled artisans. 
From the earliest days of horology, enameling has been cherished not only for its beauty but also for its ability to transform a timepiece into a true work of art. Watchmakers soon recognized that beyond precision, visual appeal made timepieces more desirable and enduring.
This meticulous craft involves applying layers of colored vitreous enamel onto a metal surface, then firing it at high temperatures—typically between 800°C and 860°C—to create a smooth, luminous finish. L’Épée draws on the time-honored Grand Feu technique, rooted in the Russian Fabergé tradition. This demanding process yields colors of exceptional depth and permanence—unaltered by time—while requiring absolute precision from the enameller.
The technique often begins with hand-decorated metal, engraved with radiating lines or intricate curves, then coated with transparent enamel to reveal the patterns beneath. In cloisonné enameling, ultra-fine gold wires—thinner than a strand of hair—are shaped into delicate cells that are filled with enamel, color by color. Each hue, created by adding specific metal oxides, is fired separately at its ideal temperature. Some pieces demand 12 to 15 firings, as even a few seconds too long in the kiln can undo days—or weeks—of painstaking work.
