Louis Erard Unveils the Limited-Edition Gravée Main

Since 2021, Louis Erard has been redefining the boundaries of Métiers d’Art, from Grand Feu enamel and guilloché to wood marquetry, and soon, gold wire inlay. Now, Gravée Main opens a new chapter, paying tribute to one of the oldest crafts in watchmaking hand engraving.
Gravée Main represents a new milestone in Louis Erard’s Métiers d’Art series. This limited edition of 99 unique timepieces places hand engraving at center stage, with every metal element entirely engraved and finished by hand, a meticulous process that requires more than 50 hours of work. 

Glossary

Atomic clock

Atomic clock's refers to a highly accurate timekeeping mechanism that utilizes the oscillations of atoms to measure time. Atomic clocks are based on the principle of atomic resonance, typically using the vibrations of atoms such as cesium or rubidium. These clocks are extremely precise, with accuracies reaching one nanosecond per day, which is equivalent to one second every 2.7 million years. Atomic clock technology is often utilized in conjunction with radio signals or satellite synchronization to ensure accurate timekeeping. By incorporating atomic clock technology, watches can maintain exceptional time accuracy, making them reliable and highly sought after by those who require precise timekeeping.
