The Louis Moinet Astronef is a mechanical watch built around two satellite tourbillons that orbit in opposite directions on separate levels. They cross paths 18 times an hour—once every three minutes and 20 seconds—beneath a domed sapphire crystal. The effect is an unusual moving display, supported by a highly openworked construction and a movement the brand identifies as calibre LM 105.
How does the Astronef double tourbillon work?
Ateliers Louis Moinet describes the Astronef’s display as two tourbillons rotating in opposite directions and at different levels. Their paths intersect 18 times per hour. The brand counts six moving elements in the display: the two satellite tourbillons, their cages and their counterweights. This is a kinetic presentation, not evidence of superior timekeeping; the cited reports provide no independent accuracy comparison.
The tourbillons and counterweights
According to the brand, each cage weighs 0.25 grams and completes one rotation in 60 seconds. Each is paired with an 18-karat gold counterweight described as weighing 0.4 grams. These figures are manufacturer descriptions, not independently measured specifications.
The movement behind the display
Ateliers Louis Moinet identifies the movement as calibre LM 105. Its brand materials describe two barrels and 471 components; the 2024 brand-news account also specifies 16 ceramic ball bearings and different rotation rates for the two tourbillons. The 2022 brand-news item says one movement is crafted per month. These are brand-reported details.

What makes the Astronef’s construction distinctive?
The moving display sits beneath a domed sapphire crystal, with a case architecture that combines a sapphire container and an 18-karat gold frame. Brand materials also describe openworked lugs and case middle, plus an applied inner bezel.
The dial plate is described by the brand as 0.6 mm thick, with 0.2 mm hollowed out to expose the numerals and a rack. The stated aim is to create visual depth while helping legibility. The resulting design makes the mechanism part of the display rather than hiding it behind a conventional dial.
Which Astronef editions have been reported?
Ateliers Louis Moinet’s March 2022 brand-news item said eight Astronef watches would be produced. In January 2024, a separate brand-news item described a Grade 5 titanium edition, also limited to eight pieces, alongside the original 18-karat red-gold edition. The dated accounts establish separate eight-piece limits; they do not establish that the first production statement covered both editions.

Is the Louis Moinet Astronef available in titanium?
Yes, a Grade 5 titanium edition was described in a January 2024 Ateliers Louis Moinet brand-news item. It was reported as limited to eight pieces and paired with red-gold tourbillon cages and counterweights. The report confirms the edition’s description, not current stock or availability.
Why the Astronef is more than a technical display
The Astronef’s identity comes from the way it stages its mechanism: two small rotating systems crossing on separate planes, framed by sapphire and openworked case elements. Ateliers Louis Moinet’s 2022 brand-news text cites the maxim, “Produce an excellent and curious effect”, attributing it to Louis Moinet. It is apt as a description of the watch’s visual ambition, though the cited source does not independently verify the quotation as archival.
