Presented at Baselworld 2016, the creation stands out by its concept and execution.

The 2 oversized tourbillons (14.9 mm) are rotating in opposite directions. They are also linked to the discs (two, on top of each other) at 12 o’clock. Their motion on the dial is pure pleasure! The development of the mechanical complications was very challenging as they are placed (the tourbillons) above the movement and even above the dial… Nice!

Exclusive to Louis Moinet, the caliber has 2 patents pending.

Regarding the two discs at 12 o’clock, the first one (on top) is hand painted and represents a constellation with stars & planets. The second (lower one) shows through an aperture, Three planets: Mars - Mercury - Moon.
Here is a quote from Jean-Marie Schaller, ceo of Louis Moinet :

“Each of the micro-paintings includes genuine dust from the heavenly body in question: a fragment of Mars, moon dust, and extremely rare fragments of the Rosetta Stone, whose scientific name is Sahara 99555. This stone has travelled across the universe to reach us: it’s the oldest known to mankind, believed by the scientific community to have come from Mercury and to be four and half billion years old. Fragments of meteorites from Mars, the Moon and Sahara 99555 also appear on the lower disc, positioned between the planets, floating in the cosmos, or included in a hand-painted shooting star.”

Amazing mechanical timepiece! We can stay hours looking at the tourbillons and its Sideral aesthetic is as original as well executed.

Bravo! Louis Moinet.
