Born in 1978, the Arceau watch combines understatement and creativity. Its round white gold case set with 70 diamonds rests on a stirrup, creating a timeless yet singular shape.

An astral world sculpted in aventurine, mother-of-pearl, aragonite and opal appears framed by a halo of diamonds is a play on materials and textures and invites contemplation of distant planets. Relief and depth effects are the result of meticulous artisanal work that involves refining aventurine until it becomes translucent and associating it with Tahitian mother-of-pearl, whose iridescent shimmer evokes the Northern Lights.

As if about to stage an eclipse from the dial, a generous freshwater mother-of-pearl moon faces the luminescence of a planet made of aragonite. In the distance an opaline star shines amid a constellation of diamonds, bright stars in the night sky.

This dreamlike interpretation of the solar system beats to the rhythm of the Manufacture Hermès H1837 self-winding movement and the Petite Lune module, driving displays of the hours and minutes, as well as the moon phases between 10 and 11 o’clock. A blue sapphire alligator strap crafted in the Hermès Horloger workshops sets the perfect finishing touch to the Arceau Petite Lune watch.
