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.

century leap year

A century leap year refers to a specific year within a century that is considered a leap year in the Gregorian calendar. Normally, a leap year occurs every four years, but there is an exception for century years. According to the rules of the Gregorian calendar, a century year is only considered a leap year if it is divisible by 400. This means that years such as 1600 and 2000 are leap years, while years like 1700, 1800, and 1900 are not. This rule helps maintain the accuracy of the calendar system and ensures that the length of a year remains consistent over time.
