Architecture in Gold. Mechanics in Suspension.

Created during Gucci's extraordinary push into high watchmaking, the 25H Skeleton Flying Tourbillon places an openworked manual-wind calibre inside an extraordinarily slender 40mm architecture, then executes the case and integrated five-link bracelet in solid 18K yellow gold.

At six o'clock, the flying tourbillon appears almost detached from the structure around it, turning technical complexity into the visual center of the watch.

Intro

The remarkable thing about the Gucci 25H Skeleton Tourbillon is not simply that Gucci made a tourbillon.

It is how completely the house committed to the idea.

At only approximately 8mm thick, this 40mm high-watchmaking piece combines an open architecture, a flying tourbillon, an integrated gold bracelet and the manually wound Gucci-exclusive Calibre GG727.25.TS. Contemporary coverage confirms that the precious-metal bracelet editions were produced in 100% recycled yellow or white gold.

Description

The Gucci 25H marked a fundamental shift in the house's approach to watchmaking.

Rather than treating the wristwatch principally as an accessory to the fashion collections, Gucci began building the 25H around increasingly ambitious Swiss mechanical movements. The Skeleton Flying Tourbillon represents one of the clearest expressions of that transformation.

Its design begins with proportion.

The approximately 40mm case measures only around 8mm in thickness, creating an unusually thin silhouette for a watch incorporating a flying tourbillon. Gucci constructed the watch around the movement itself, allowing the mechanics to appear suspended above a sequence of horizontal structural bridges.

There is effectively no conventional dial competing for attention.

Instead, the architecture of the GG727.25.TS becomes the dial.

At six o'clock sits the flying tourbillon, unsupported by a conventional upper bridge and visually isolated within the skeletonized composition. Above it, the openworked hour and minute hands cross a landscape of bridges, wheels, jewel settings and the prominent Interlocking G motif.

The movement is manually wound and operates at 3 Hz, or 21,600 vibrations per hour. The Gucci specification sheet supplied with this watch states 20 jewels and approximately 72 hours of power reserve, specifications independently corroborated by contemporary coverage of the calibre.

The case and bracelet transform the technical object into something considerably more sculptural.

The supplied Gucci specification sheet identifies a 40mm multi-layered case and five-link bracelet in 18K yellow gold, and specifies an average gold weight of approximately 189.3 grams of 18K yellow gold. That figure is a manufacturer specification rather than an independently weighed figure for this individual watch.

The horizontal construction of the bracelet continues the geometry of the movement. Instead of treating the bracelet as a separate attachment, the five-link structure appears to flow directly outward from the case.

Contemporary reporting confirms that Gucci offered the Skeleton Tourbillon with matching precious-metal bracelets in both yellow and white recycled gold. The yellow-gold bracelet edition was originally publicized at approximately €140,000 at launch, while another industry reference placed the bracelet version at HK$1,460,000.

The caseback provides another view of the movement.

Horizontal bridges decorated with repeated Interlocking G motifs frame the visible gear train, while the inscription GG727.25.TS / 20 TWENTY JEWELS identifies the calibre architecture visible in the photographs supplied with this example.

This is therefore not simply a gold version of a conventional Gucci watch.

It belongs to the period in which Gucci deliberately entered the terrain of serious contemporary haute horlogerie, using the 25H architecture to explore ultra-thin movements, openworked construction and high complications.

Condition Report

Case

The watch is almost unused in mint condition.

The supplied photographs show the yellow-gold case retaining a strong, coherent brushed finish and well-defined multi-layer architecture. Fine handling marks or extremely light surface hairlines may be present under directional lighting, which is normal for large surfaces of 18K gold.

There are no obvious major dents, structural deformations or deep impacts visible in the photographs supplied.

No claim is made that the watch is completely unworn or unpolished.

Skeleton Display

The openworked display presents cleanly in the photographs.

The structural gold-tone elements, movement components and flying tourbillon remain visually crisp, with no obvious dial-side corrosion, moisture intrusion or displaced components visible from the supplied images.

Movement

The photographed caseback clearly presents the skeletonized movement architecture and the GG727.25.TS designation.

The visible seller description does not provide timing-machine results, amplitude, service history or an explicit mechanical test report.

Accordingly, Japonista should not claim a particular daily rate or recent servicing until those points are confirmed before acquisition.

Bracelet

The integrated five-link yellow-gold bracelet presents strongly and appears structurally complete in the supplied photographs.

Because bracelet sizing materially affects both wearability and value, maximum wrist circumference and presence of all original removable links should be confirmed before purchase.

Crystal / Caseback

Front and rear sapphire surfaces appear clear in the supplied photographs without obvious major impact damage.

Fine handling marks cannot be excluded from photography alone.

Why Collectors Want This Piece

The 25H Skeleton Tourbillon comes from a particularly unusual moment in modern watchmaking.

Gucci had already produced Swiss watches for decades, but the 25H represented a conscious move toward proprietary movement architecture and genuine high complications. Gucci itself identifies the 25H as the collection that introduced its first original movement in 2021, and the Skeleton Tourbillon followed during the house's 50th-anniversary watchmaking celebrations.

This particular configuration adds three ingredients that considerably change its collector profile.

First is the GG727.25.TS flying-tourbillon movement.

Second is the extraordinary thinness. Housing a skeleton flying tourbillon in a watch approximately 8mm thick gives the object a delicacy that contradicts the visual mass of the gold bracelet.

Third is the full precious-metal architecture. The bracelet edition carries the concept much further than the rubber-strap configuration because the case and five-link bracelet form a single uninterrupted gold structure.

The model was also entered in the 2022 Grand Prix d'Horlogerie de Genève Tourbillon category, placing it directly among specialist high-horology pieces rather than Gucci's conventional fashion-watch offering.

That combination makes the watch intellectually interesting even to collectors who would not ordinarily consider Gucci a traditional haute-horlogerie marque.

Brand Heritage

Founded in Florence in 1921, Gucci developed its Swiss watchmaking activity during the twentieth century and began producing watches in Switzerland in 1972.

The arrival of the Gucci 25H in 2021 marked a new phase. The collection introduced Gucci's first original movement architecture and adopted an ultra-thin, integrated-bracelet design influenced by contemporary architecture.

For the house's 50th year of Swiss watchmaking, Gucci expanded the concept dramatically through the Gucci Wonderland high-watchmaking collection, including the Skeleton Flying Tourbillon seen here.
