A Miniature Theatre of Horology and Equestrian Poetry – Hermès Arceau Cavalier en Formes

The Hermès Arceau Cavalier en Formes is a watch that tell a story, and a piece that seems to exist in an entirely different philosophical register. Since Henri d’Origny conceived the Arceau in 1978, Hermès has used that round case with its signature asymmetrical stirrup-shaped lugs as a canvas for its most ambitious artistic and horological ambitions. The Cavalier en Formes is, without exaggeration, one of the most complex expressions of that philosophy to date. It brings together a flying tourbillon, a minute repeater, miniature painting on sapphire, and hand-engraving, all orchestrated by artist Gianpaolo Pagni, who drew inspiration from an equestrian lithograph in the Émile Hermès collection to produce a composition originally conceived for a silk scarf. That final detail matters enormously: this is not a decoration designed for a watch face, but an artistic language transplanted from one medium to another, retaining every gram of its evocative power in the process.

Painting, Engraving, and Sculptural Depth

The dial of the Cavalier en Formes represents one of the most technically demanding surfaces in contemporary Haute Horlogerie. Hermès places a sapphire crystal directly onto the dial plate, then applies miniature painting on both its upper and lower faces, creating a layered visual landscape where colour, transparency, and depth interact in ways that shift with every change of light. Finely engraved leaves unfurl across the surface, and hand-painted blue flat-colour blocks in square and round shapes bring Pagni’s cubist-inspired rider to life, a figure suggested through geometry rather than depicted literally. At the centre, an engraved yellow gold horse stands as the compositional anchor, while the interplay of superimposed engraving, painting, and transparency produces what the Maison aptly describes as almost sculptural depth.

Calibre H1924 and Its Grand Complications

The hand-wound Manufacture H1924 calibre sits at the heart of this piece, and it is a movement of genuine substance. Measuring 30 mm in diameter and 6.1 mm thick, it beats at 21,600 vibrations per hour (3 Hz) and delivers a remarkable 90-hour power reserve. The calibre carries two complications of the highest order: a flying tourbillon positioned at 6 o’clock, and a double-gong minute repeater. The tourbillon carriage replicates the iconic “double H” motif from the wrought-iron lift inside the Hermès boutique at 24 Faubourg Saint-Honoré, a detail that is both architecturally precise and quietly poetic.

The barrel bridge takes the form of twin horse heads, reinforcing the equestrian narrative at the mechanical level. Finishing on the H1924 includes dark rhodium-plated bridges with vertical brushing and polished, bevelled edges, black-polished repeater hammers, and a tourbillon cage that alternates between brushed and polished surfaces. Produced by Manufacture Haute Complications (MHC) in Geneva, the movement is a well-regarded platform that Hermès has made unmistakably its own through the architectural choices built into each iteration.

White Gold and Restrained Architecture

The 43 mm round case in white gold continues the Arceau’s foundational design logic: apparent simplicity in service of extraordinary content. The asymmetrical stirrup-shaped lugs remain the defining gesture, and Hermès pairs them here with an anti-glare sapphire crystal on both the front and the case-back, allowing the movement to remain visible from either side. Water resistance reaches 3 bar, and the bleu abysse alligator strap, crafted in the Hermès Horloger workshops, completes a colour dialogue with the hand-painted blue blocks on the dial. The case-back view reveals the full architectural spectacle of the H1924, with its rhodium-treated bridges and the double-H tourbillon cage rotating against the dark mechanical landscape below.

A Unique Object in Six Copies

Hermès issues the Arceau Cavalier en Formes in a limited edition of just six pieces, placing it firmly in the territory of objects one acquires through conversation with the Maison rather than from a retail shelf. The watch is a fully realised dialogue between Hermès’s leather and silk heritage, its watchmaking workshop, and a tradition of decorative arts that the house has cultivated over nearly two centuries. The Arceau Cavalier en Formes does not ask to be understood at a glance, but it asks to be worn, listened to, and studied and enjoyed over time.
