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.

Oils

Oils

Are substances used to lubricate and protect the components of a watch movement. The oils work to reduce friction between the moving parts and minimize the wear caused by constant rubbing. This helps improve the performance of the watch and ensures smooth and accurate operation.

The types of oils used in watches vary depending on their function and where they are applied. There are oils specifically designed for lubricating bearings, pivots, and pallets, and there are oils specifically formulated for lubricating the mainsprings and the gear train of the watch. These oils differ in their viscosity, saturation level, and resistance to oxidation.
