Over the moon with the Hermès Arceau L’heure De La Lune

The Arceau L’heure De La Lune watch, showcased at SIHH 2019, offers a unique vision of the moon, with the simultaneous display of moon phases in both northern and southern hemispheres.

The Arceau L’Heure De La Lune shows a pair of stationary mother-of-pearl moons with a complementary pair of lacquer dials floating over the top that rotate around the dial once every 59 days, covering and uncovering the moons to indicate the current moon phase in both the southern and northern hemispheres at once.

One of the floating dials shows the hours and minutes, while the other counts the date. Hermès has furthered the dreamy effect by inverting the moons – the top one showing the southern hemisphere and the lower one showing the northern hemisphere.
