Sideralis by Louis Moinet

For the first time ever, a complication is driven by a double tourbillon: a time dial, situated at 12 o’clock, comprising two discs, one atop the other. The top one features a tiny hand-painted picture. This hand-crafted marvel depicts the universe and its constellations of stars and planets, painted one by one on a dark blue sidereal background. The animation completes one counter-clockwise rotation every 60 seconds. At 12 o’clock on this upper disc there is a circular opening, through which can be glimpsed the three planets painted on the lower disc, seen to be rotating in the opposite direction at the same speed. The feature represents a wholly new conceptual and artistic approach.
