Unveiled at this year’s World Presentation of Haute Horlogerie (WPHH), the Vanguard Aero Revolution 3 Skeleton sees Franck Muller return to its tri-axial tourbillon lineage through a far more exposed and spatially ambitious construction, pairing the complication with a fully openworked case designed to frame the movement from multiple angles.

The new watch shifts the emphasis from the complication alone to the architecture around it, turning visibility, structure and mechanical theatre into part of the proposition. The Revolution 3, the world’s first tri-axial tourbillon, was first introduced in 2004 by Franck Muller, and this new Vanguard Aero Revolution 3 Skeleton is now presented as a new interpretation of that expertise, with case and movement closely intertwined.

A Revolution 3 lineage revisited

The Vanguard Aero Revolution 3 Skeleton is housed in an 18K rose gold Vanguard case, measuring 43.90mm by 52.10mm, and is openworked on all four sides.

To understand why the Vanguard Aero Revolution 3 Skeleton matters, it helps to place it within Franck Muller’s own technical history. The Revolution 3 occupies a significant place within the house, not simply as a grand complication, but as one of its landmark “world premieres”. It introduced the first tri-axial tourbillon in 2004 after years of development, creating a system designed to counter the effects of gravity in all positions rather than only in the vertical positions addressed by a classical tourbillon. For the Vanguard Aero Revolution 3 Skeleton, the significance  lies less in the complication itself than in the way Franck Muller has chosen to reconstruct its presentation.

What is genuinely new here is an architectural treat. With the Vanguard Aero Revolution 3 Skeleton, Franck Muller places unusual emphasis on the case as a technical instrument rather than a simple container. The 18K rose gold Vanguard case, measuring 43.90mm by 52.10mm, is openworked on all four sides and reduced to what the brand describes as the strict minimum, with the aim of allowing unobstructed views of the movement from multiple angles while preserving structural integrity and wearability.

More importantly, the movement here is mounted directly onto the caseback in an unprecedented configuration for the brand. Rather than treating the case and calibre as separate elements, Franck Muller has rethought the bridges, barrels and gear train around this open architecture so that the movement can effectively inhabit the case in a more integrated way. The crown system, too, has been re-engineered to work within this openworked structure while preserving water resistance, while a corrector discreetly integrated into the caseback crystal allows adjustment without interrupting the visual purity of the watch.

This is where the real advancement lies: not in inventing a new complication, but in re-staging a familiar one through a more radical union of movement and case.

A tri-axial tourbillon, staged for maximum exposure

The new in-house manually wound calibre, MVT FM 2031-SMR-VS-NR, consists of 280 components.

At the centre of the watch remains the tri-axial tourbillon that gives the Revolution 3 its identity. The complication’s theatrical and technical appeal is preserved, with three concentric cages rotating on different axes: the inner cage completing one rotation every 60 seconds, the intermediate cage every eight minutes, and the outer cage every hour. As the brand has long explained, the purpose of this arrangement is to multiply the positions of the balance wheel in space and thereby compensate for gravity in all positions.

In the Vanguard Aero Revolution 3 Skeleton, however, that mechanism is no longer simply something to be admired through apertures in the dial. The new in-house manually wound calibre, MVT FM 2031-SMR-VS-NR, consists of 280 components and has been developed specifically for this open architecture. Its skeletonised construction, off-centred hands and extended sightlines place the tri-axial regulator at the centre of a far more immersive visual experience. The new movement pairs that continuous motion with twin barrels delivering a 10-day power reserve, an especially notable figure given the energy demands of such a system.

The Vanguard case is part of the challenge here, and arguably, part of the achievement. Franck Muller’s signature tonneau-shaped Vanguard architecture has always carried strong visual identity, but in this instance its curved form becomes a technical constraint as well. The curved contours demand exceptional precision in machining and assembly, all the more so in a case that has been opened on all sides and reduced so dramatically in visual mass.

A new architectural expression of a house signature

The crown system has been re-engineered to work within this openworked structure while preserving water resistance.

The most accurate way to understand the Vanguard Aero Revolution 3 Skeleton, then, is not as a wholly new invention, but as a new architectural expression of one of Franck Muller’s signature inventions. The tri-axial tourbillon remains a cornerstone of the house’s technical identity, but here the emphasis has shifted towards the way that complication is housed, supported and revealed. By opening the case on four sides, mounting the movement directly to the caseback and treating the case itself as a frame around the mechanism, Franck Muller has turned an already dramatic complication into something more spatial, more immersive and more structurally resolved.
