Reine de Naples Jour/Nuit 8998

This model’s patented movement features a display with two dials, with one representing the hours and minutes in a traditional manner, and the second showcasing the complication that indicates the time of the day and the night. The sky is represented by a lapis-lazuli disc inlaid with natural white mother-of-pearl clouds, gold stars and a hand-engraved titanium moon. But the true star here is the sun, represented by the felloe of the faceted balance wheel that evokes the rays of the sun. It makes one rotation over the course of a full day, passing under the steel bridge that supports the mechanism and which faces the moon.
