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.

Isochronism

Isochronism

In watches refers to the ability of a watch to keep consistent time regardless of the power reserve or the amount of winding. A watch with good isochronism will maintain the same accuracy throughout its running time, this is achieved through the use of a high-quality balance wheel and hairspring system, which ensures that the oscillations of the balance wheel remain consistent and regular. Isochronism is an important quality in a watch as it ensures reliable timekeeping and accuracy over an extended period.
