Official description

If watchmaking is born of astronomy, the Moon is the inspirational element. The Moon allowed ancient peoples to understand the early divisions of time and the passage of the seasons. It helped us grasp the notion of time that comes and goes at a steady pace: a concrete manifestation of the “cycles” that structure our comprehension of time to this day.

Waxing and waning through the phases of the new moon, first quarter, full moon and last quarter, the Moon brings poetry to watchmaking. It breathes into the mechanical the tender mystery of a celestial body, the secret of a satellite that remains –despite its relative proximity to us– largely unknown. The dark side of the Moon continues to be one of the great mysteries in space exploration.
