2460 R31L/2 description
This 275-component movement can be admired through the sapphire caseback, notably the circular-grained surface of its mainplate and its 22K gold oscillating weight adorned with a stylised compass rose recalling the themes travel and exploration. The moon phases are displayed through a 6 o'clock aperture graduated from 0 to 29½ and thus serving to read off the number of days elapsed since the last new moon. This complication, known as the age of the moon, corresponds to the actual cycle of this heavenly body which completes one full rotation around the Earth in exactly 29 days, 12 hours and 45 minutes. The precision moon-phase mechanism requires a one-day correction only every 122 years. The retrograde date indication by central hand occupies the upper part of the dial.
For enhanced user-friendliness, all adjustments are done via the crown: winding, correction of the date and moon phases, as well as setting the time.
