At the revealing of the manufacture's latest offering, Jean-Marie Schaller, CEO of Louis Moinet, waxes lyrical. "Sideralis is an invitation to embark on an interstellar journey,” said Schaller. "A whole new kind of discovery that’s singularly technical and poetic." This description, in itself, speaks volume. Defying comparison and elevating itself among all the other watches created by man, Louis Moinet Sideralis is in a class of its own. This model has been borne out two patent applications, created by a fully-independent firm whose sole desire is to invest in new components that will satisfy and inspire lovers of Swiss luxury watches.

Perhaps the word to describe Sideralis is staggering—it is a watch structured around two exemplary tourbillons, both of which are hefty in size, being placed inside cages of 14.9 mm. This is double the size of a regular tourbillon. Schaller notes that this approach "adds a fascinating visual dimension to the watch; a touch of magic that we've decided to gift lovers of fine watches, just so they can contemplate beauty and horological art in all its splendour." The second intriguing feature of the two tourbillons is that they are designed above the movement, even the dial. The two raised cages are wholly visible, portraying the balance wheels with stunningly designed screws, among its absolutely unique aesthetic appearance. Last but not least, these tourbillons rotate in opposite directions; they come and go not for style appeal, but for counter rotation. This provides the motive power as demanded by the central complication: the star of Sideralis.

Louis Moinet has truly moved the stars in order to create such new mechanism. A time dial, found at 12 o'clock position, is made with two layers of discs. The top features a hand painted mural. This tiny spectacle depicts the universe and the thousands of stars as well as planet, all painted one by one on a dark blue sideral canvass. The animation is completed through a counter-clockwise movement every 60 seconds. A circular opening on this upper disc is a glimpse of three planets painted on the lower disc, running on the same pace, but going on a different direction. These planets, it must be said, are chosen for a reason; they depict a heavenly body which has travelled across the galaxy to reach us, a stone oldest known to mankind. It is said to have come from Mercury and contains elements of moon dust and Mars. The shooting star, Sahara99555, a gift from the universe aged billions of years, a prized gem whom everyone alludes to as the Rosetta Stone.
