Hermès ARCEAU L’heure de la lune, New Models

In 2020, Hermès is unveiling new interpretations of its ARCEAU L’heure de la lune, a high horology creation that offers a unique vision of Earth’s satellite with the simultaneous display of moon phases in both northern and southern hemispheres.

The new Hermès ARCEAU L’heure de la lune watches are available in white gold or platinum case. Two mobile counters gravitate on a lunar, Martian or Black Sahara meteorite dial, revealing mother-of-pearl moons in step with an exclusive module, coupled with a Manufacture Hermès movement. Meteorite inlaid with mother-of-pearl form a cosmos in which satellite dials float above hemispherical moons. These mischievous displays have swapped cardinal points, with the south above and the north below.

The new models being released this year are white gold versions with Black Sahara meteorite dial (limited edition of 30 pieces) or lunar meteorite dial (limited edition of 36 pieces) and a Platinum version with Martian meteorite dial (limited edition of 2 pieces).

The horse, representing the origins of Hermès, gallops elegantly into the world of dreams. At 12 o’clock, the moon is adorned by a Pegasus designed by the “dreamer-designer” Dimitri Rybaltchenko. Entitled Pleine Lune (Full Moon), this portrayal of the winged horse hints at a passage between two worlds, where magic and reality merge.

On the other side, at 6 o’clock, the view of the moon from the northern hemisphere provides a realistic depiction of its surface. The mobile counters displaying the time and date turn weightlessly to reveal the moon discs, while maintaining their horizontal orientation. This contemporary dance is choreographed by a module exclusively developed for Hermès and for which a patent has been fled.

With a total thickness of just 4.2 mm, its 117 polished and bead-blasted components are incorporated within the Manufacture Hermès H1837 movement: a technical challenge designed to preserve the slenderness of the overall mobile chassis, which sweeps around the dial in 59 days.

The mother-of-pearl moons set into the stone display the lunar cycles in the northern and southern hemispheres. This mysterious game of hide-and-seek reveals nothing of its technical complexity, so as to give pride of place to dreams. Within this space-time, metal, stars and rock seamlessly merge the watch exterior with the movement to form an unprecedented technical and aesthetic display of simple and graphic readability.

The double moon here eclipses a traditional aperture-type display, instead covering the entire surface of the dial. The result is a free-spirited and impertinent vision of mechanical watchmaking according to Hermès.

The Arceau case with its asymmetrical lugs, designed by Henri d’Origny in 1978, becomes a lunar crater made of meteorite stone, while the lacquered dials, gravitating like satellites, display Arabic numerals with a distinctive sloping font.

The ARCEAU L’heure de la lune timepiece is fitted with a matt alligator strap in black, Havana or Veronese green, depending on the versions.
