Limited Editions of 3 watches



An interstellar inverted double tourbillon
“Acasta is an invitation to embark on an interstellar journey through a complete skeletonized movement – a whole new kind of discovery that’s singularly technical and poetic”. The timepiece in question defies comparison, simply because to date, Acasta does not have any equivalent anywhere in the world of watchmaking, and is protected by two patent applications.

Sidereal – and staggering
Acasta is structured around two especially extraordinary tourbillons:
- Both of these tourbillons are oversized, with cages measuring 14.9 mm – half as big again as the average. This is the largest assembly of two tourbillons
ever to have existed.
- The two tourbillons are designed to be physically above the skeletonized movement. The two raised cages are revealing balance wheels with beautifully styled screws – and an absolutely incomparable aesthetic appearance.

Tourbillons move a blue-tinted titanium disc
This exceptional timepiece is presenting an exclusive movement to Louis Moinet. Suspended in mid-air, the two tourbillon cages weigh a mere 0.4 grammes each, but nonetheless generate enough energy to power a rotating disc – made from blue-tinted titanium and featuring openwork arabesque patterns adding a further touch of mystery.

Acasta gneiss
A rock that has had to withstand the forces of erosion and tectonics for four billion years. It’s a fragment of the early earth’s crust, preserved intact ever since. Today, thanks to Louis Moinet, Acasta has become an outstanding dial on which to display the time.
