Astronef Techno

A visual revolution in mechanical art

ASTRONEF TECHNO is an innovative and very expressive timepiece matching revolutionary mechanics with high-end materials. This unique timepiece pairs a silicon wafer engraved with microelectronic circuits with an ingenious double satellite tourbillon, thus producing a never-seen visual spectacle.

As the namesake of the brand did in his time, Louis Moinet is paving the way to the future of watchmaking with this outstanding creation.

A continuous quest for innovation

Louis Moinet has generated horological adrenaline by matching revolutionary mechanics with high-end materials.

The result: a series of masterpieces that are both innovative and very expressive, like the ASTRONEF TECHNO. This timepiece pairs a silicon wafer engraved with microelectronic circuits with an ingenious double satellite tourbillon, thus producing a never-seen visual spectacle.

ASTRONEF's revolutionary mechanics in action.

Animating a work of art

Two satellite tourbillons revolving around the dial and creating a harmonious ballet in the process.

They cross paths 18 times per hour (every 3 minutes and 20 seconds) and are built on two different levels.

They are inside cages each rotating at a different rate, the one in ten minutes, the other in five. Every three minutes and twenty seconds, the two tourbillons align perfectly, which demands perfect synchronization and accuracy, the ASTRONEF’s superpower, as it were.

These tourbillons, with their delicate and crisp lines, barely weigh 0.25 grammes each. The counterweight is a real exploit in terms of design and engineering. It adds to the spectacle, creating a kind of intimate pas de trois, merging art, engineering, and motion, thanks to a central differential. Needless to say, it increases the watch’s precision.

The movement side of the ASTRONEF TECHNO is just as impressive. The open case back reveals two barrel springs, one for each tourbillon, delivering a 48-hour power reserve. The LM 105 calibre, which includes sixteen ceramic ball bearings, runs this mechanical show. It took three intense years to make.

And there are other innovations. The crown, for instance, has been entirely reinvented and no longer needs to be pulled. Instead, a selector, cleverly integrated into the case back, is used to control two key functions, time-setting and winding.

The epitome of tech-art

The ASTRONEF TECHNO has taken an edgy material and turned it into a work of animated art. The timepiece’s double satellite tourbillon travels over a canvas carefully cut from a silicon wafer, an exacting material upon which the engraved microelectronic circuits appear as a kind of complex technological decoration. The modern dial catches the light with every move of the wrist, turning it into a kaleidoscope of sparkling reflections and transforming this masterpiece of mechanical watchmaking into a mesmerising visual experience.

Harmony of content and form

The case for the ASTRONEF TECHNO’s exceptional mechanism is the product of imaginative engineering: It is made up of a bold ensemble of sapphire band, flange and top resting on a grade-5 titanium frame.

The lugs have been carefully openworked, which enhances the feeling of lightness. It’s a unique concept for a casing and it gives the timepiece its resolutely avant-garde look.

The Louis Moinet ASTRONEF TECHNO weaves together time and space on a canvas that appears to be constantly in motion. This fusion of the visually compelling microelectronic wafer with the dance of the tourbillons above it creates a unique artistic event that opens a new era in horology.

The technical construction of the case is unusual:
  • a sapphire container mounted on grade 5 titanium frame
  • openworked lugs and case middle
  • a sapphire dome and welded inner bezel ring

A mysterious mechanism

The mechanism is hidden in the base of the frame, which is only 3.75 mm thick. The advantage of this construction is that it clears the stage to enhance the magic of the show being staged.

Secrets of the mechanism

For enhanced accuracy

Perfect rotation and poising of the rotating elements

Five ball-bearing mechanisms with seven ceramic bearings
One ball-bearing mechanism with nine ceramic bearings

Two barrels

Each supplies its energy to the tourbillon

Original time-setting

Placing the selector on the back of the case enabled a gain in volume and this device plays two distinct roles: time-setting or winding. The crown is no longer pulled out; it is used to set the hands or to wind the mechanism.
