Minerva Brings Its Goddess Back on the Exo Tourbillon Skeleton

Minerva’s return to centre stage now has a watch to match the moment.

The Exo Tourbillon Skeleton Limited Edition places the Villeret manufacture’s name, mechanics and mythology firmly in view, without the dual branding that previously framed much of its modern high-watchmaking work.

Limited to 18 pieces in rose gold, it combines a skeletonised manual-winding calibre with an agate cameo of the Roman goddess Minerva, turning a technical showpiece into a statement of identity.

At a glance

• Minerva has introduced the Exo Tourbillon Skeleton Limited Edition as part of its move into a standalone brand structure.
• The watch features the patented Exo Tourbillon mechanism with a 14.5mm balance wheel positioned above and outside the rotating cage.
• Production is limited to 18 pieces in rose gold, with pricing still to be confirmed.

Minerva steps out under its own name

Minerva’s modern story has often been intertwined with Montblanc, following Richemont’s acquisition of the manufacture in 2006 to strengthen Montblanc’s watchmaking credentials.

That arrangement produced serious haute horlogerie, but it also created a certain ambiguity around authorship.

With Minerva moving to a standalone brand structure in 2026, the Exo Tourbillon Skeleton feels less like a relaunch exercise and more like a clarification.

The manufacture remains connected to the Montblanc Maison, but the emphasis here is unmistakably on Minerva’s own heritage, its finishing culture and its Villeret identity.

A skeleton calibre built around the Exo Tourbillon

The watch is built around Minerva’s patented Exo Tourbillon, a mechanism introduced in 2010 that separates the balance wheel from the rotating tourbillon cage.

The name comes from the Greek word “exo”, meaning outside, and the architecture makes that idea literal.

A large 14.5mm balance wheel is raised above the cage, sitting on a higher plane rather than being carried inside it.

The 60-second tourbillon cage turns beneath it, with a heat-blued Minerva arrow hand marking the running seconds.

At 6 o’clock, the mirror-polished cage is held by a one-arm bridge and carries the number 10 written in Sumerian.

The suspended balance beats at 2.5Hz and reveals 18 small gold regulation screws, a detail that gives the open dial a strong mechanical focal point.

The manual-winding calibre M18.69 is composed of 188 hand-assembled components and is skeletonised to allow light through both sides of the case.

Its openworked bridges show hand-chamfered angles, while the movement is finished with 400 hand-polished inner bevels, mirror-polished surfaces, frosting and circular graining.

The caseback continues the visual argument with details including a mirror-polished ratchet wheel and a winding pawl shaped like a Minerva arrow.

The goddess returns to the dial

Minerva’s official emblem, Minerva’s Arrow, was registered in 1887, and the Roman goddess herself has long appeared in the brand’s visual history.

On this watch, she returns as a cameo on the hours and minutes sub-dial.

The cameo uses a polished Persian blue agate base beneath a white agate profile of Minerva, recalling the hardstone relief carvings associated with antiquity.

The white agate element is recessed and laser-textured before being engraved and painted by hand.

It’s a small but significant choice, because it avoids treating heritage as a logo exercise.

Instead, the watch brings Minerva’s patron figure into the mechanics of time display, where she becomes part of the dial architecture rather than a decorative afterthought.

A related classical motif appears on the rose gold-coated tourbillon frame, which is decorated with a frieze pattern and engraved with the Minerva name filled in blue lacquer.

Rose gold, fluting and Villeret finishing

The case measures 44.8mm in diameter and 15mm thick, giving the watch the scale needed for an exposed construction of this kind.

It is fully polished in 18k rose gold, with stepped lugs and a fluted winding crown.

The bezel also carries Minerva’s signature fluting, a house detail dating back to 1927 and appearing here for the first time on an Exo Tourbillon.

The rose gold tone extends into the movement itself, where much of the skeletonised architecture is rose gold-plated, including the curved bridges, going train and suspended tourbillon bridge.

The result is warm and highly legible, with the Persian blue agate and matching alligator strap bringing contrast to an otherwise luminous composition.

The watch is fitted with a rose gold triple-folding clasp.

Details & Specifications

The Exo Tourbillon Skeleton is clearly aimed at collectors who care as much about authorship and finishing as they do about complication count.

For Minerva, it’s a symbolic piece of watchmaking, with the goddess, the arrow, the fluting and the openworked calibre all pointing in the same direction.
