Mobilis is an inverted double tourbillon by the brand Louis Moinet. The two tourbillons in the bottom half of the dial rotate in opposite directions, and are both linked to the gear train in the top half. It’s a mesmerizing sight to watch, because, with sapphire glass front and back, the two tourbillons seem to be floating. While everything is in any case on view, the way that the gear train has been placed at the top of the watch, behind the open-worked dial, creates a remarkable sense of space.

The hand-wound movement was made in collaboration with Tec Ebauches SA, and it includes two inventions that are patent pending and so are for the moment entirely secret. The detailing of the piece is superb, and there is even a secret Louis Moinet signature on the inner bezel flange. It is made in white gold, a limited edition of 12 pieces. Price is 245,000 Swiss francs, available from spring 2017.

The name, Mobilis, continues the tradition of words ending in “is,” and they are all invented by CEO and Creative Director Jean-Marie Schaller. He said, at the presentation, “Yes, I think of the names, and then we have to check if we can use them for a watch. I myself had a surprise. I recently discovered that Louis Moinet himself had a daughter. And do you know what her name was? Anais!”
