As we mentioned in our introduction to the watch, the Grand Récital is built around a tellurium – this is a type of astronomical complication which shows the relative positions of the Earth, Moon, and Sun. The Earth, in the Grand Récital, is represented by a hand-lacquered hemisphere, showing the Earth as seen from a vantage point above the North Pole. The hemisphere rotates once every 24 hours, and around it, a sphere representing the Moon orbits once every synodic month (29.53 days). The Sun is represented by the cage of the flying tourbillon. The hour is read off the Arabic numerals at the periphery of the globe, and there’s a retrograde minute display to the left, and a power reserve indication to the right. You can get an approximate idea of the current phase of the Moon from its position with respect to the Earth and Sun, and to help you along, the various phases of the Moon are also printed on a sort of rehaut around the Earth.
