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.

Pendulum

The pendulum is the swinging weight (back and forth) in mechanical pendulum clocks or some specialized timepieces. The pendulum swings in a regulated manner to regulate the timekeeping function of the clock.

Typically, a pendulum consists of a long metal rod with a circular disc at its end, suspended from a fixed point inside the clock movement. It swings under the influence of gravity, and its motion is controlled by the escapement mechanism or the main spring, which provides regular impulses to keep the pendulum moving.

The oscillating motion of the pendulum regulates the time and governs the movement of the clock's gears and hands. It divides time into equal periods with precise and regular oscillations, allowing for accurate timekeeping. The length, weight, and design of the pendulum are carefully calibrated to achieve the desired accuracy in displaying time.
