Hermès Arceau Petite Lune

To mark its 35th anniversary, the iconic Arceau model designed by Henri d’Origny welcomes a horological complication displaying the moon phases. Interpreted in a more feminine version with a 38 mm diameter, the Arceau Petite Lune reveals a round steel case featuring asymmetrical lugs evoking the shape and curve of a stirrup – a motif that has become a signature of the Maison Hermès.

This collection comprises two versions with a shimmering white or black mother-ofpearl. The hours are elegantly marked off on sloping Arabic numerals reflecting the original model and extending a graceful invitation to discover time.

The Arceau Petite Lune displays the hours and minutes, along with two complications delicately framed by a rhodiumed ornamental fillet: moon phases, which appear on a deep blue disc with silvered moon and stars; and a pointer-type date indication which marks off the days of the lunar cycles.

Its mechanical self-winding movement is complemented by a module serving to power the moon-phase indication. Endowed with a 42-hour power reserve, its plates and bridges are circular-grained and snailed, while its oscillating weight is adorned with a Côtes de Genève motif.

Loyal to the Hermès saddle-making expertise, this timepiece is teamed with an alligator strap available in three colours – indigo blue, elephant grey or black, crafted in the company workshops using the saddle-stitching technique.
