In 2026, the Parisian maison Hermès consolidates its unique vision of high watchmaking by redefining the design language of openworked mechanics and geometric form. Through a perspective where movement architecture transforms into a play of light, shadow, and depth, the maison introduces its latest key novelties within the H08 and Slim d’Hermès families: timepieces that skeletonize their calibres to elevate functionality into a work of art.
Hermès H08 Squelette: Graphic Transparency and Titanium Calibre
The iconic silhouette of the H08 line, created under the direction of Philippe Delhotal with its signature cushion-shaped case fusing the circle and the square, evolves into a purely architectural dimension. The new Hermès H08 Squelette reveals the inner workings of its mechanics while retaining every bit of its sporty, urban character.

Housed in a 39 mm satin-brushed titanium case with a matte DLC treatment, the timepiece is crowned by a refined black ceramic bezel featuring sunburst satin brushing and mirror-polished chamfers. The construction invites the eye to explore the gear train of the new manufacture movement, Calibre H1978S—an automatic skeletonized mechanism whose mainplate and bridges are crafted in dark-toned titanium.


⚙️ Geometry and Typography: The signature aesthetic of the H08
Applied Arabic numerals coated in Super-LumiNova® in blue or grey preserve the futuristic typography custom-designed for this collection. Suspended over the floating minute track, their graphic layout adds striking three-dimensional depth against the brass and steel wheels of the movement.
The ensemble is completed by a rubber strap featuring a «tissu» webbed pattern that accentuates the piece’s contemporary lines. On the reverse, the sapphire crystal case back offers a clear view of the openworked oscillating weight signed by the maison.

Slim d’Hermès Squelette Lune: Ultra-Thin Haute Horlogerie and Dual Moon Phase
The Slim d’Hermès collection represents the maison’s most streamlined, poetic, and purist expression. In this Squelette Lune iteration, Hermès blends the subtlety of an ultra-thin profile with striking openworked architecture surrounding one of watchmaking’s most poetic astronomical complications: the dual moon phase.

Measuring 39.5 mm in diameter, the model is offered in two contrasting executions: a polished 950 platinum case and a contemporary variant in satin-brushed DLC titanium. The openworked dial in blue or black titanium reveals a network of hand-chamfered, sandblasted bridges finished to the highest artisanal standards.

At 6 o’clock, an openworked disc displays the lunar cycle simultaneously as seen from both the Northern and Southern Hemispheres. This complication is driven by the manufacture Calibre H1953, an ultra-thin movement measuring just 3.57 mm in thickness, complete with an engraved micro-rotor integrated seamlessly into the mainplate.

Hermès H08 Chronographe: Graphene Composite and Monopusher Architecture
For enthusiasts seeking sportiness paired with high-tech materials, the Hermès H08 Chronographe elevates the collection by introducing a multi-layered composite case crafted from carbon fiber and graphene powder. This mineral compound creates a unique visual pattern on every case while ensuring light weight and high structural rigidity.

The mechanical genius of this chronograph lies in its operational simplicity: it functions via a monopusher mechanism seamlessly integrated into the black PVD titanium crown at 3 o’clock. A single press on the pusher—accented with a contrasting ring—starts, stops, and resets the chronograph mechanism.
⚡ Modular Calibre H1837: Precision and urban ergonomics
The automatic manufacture Calibre H1837 pairs with a chronograph module composed of 212 components measuring 3.3 mm thick. Notable features include highly legible sub-dials with softened contours and a date window discreetly angled at 4:30.

Reflection: The Triumph of Form Over Convention
With this trio of releases, Hermès once again demonstrates that its approach to Haute Horlogerie bypasses traditional industry conventions. Where other manufactures treat skeletonization purely as a display of technical bravado, the Parisian house employs it as a design medium—one where typography, shadow, and light take center stage. From the architectural presence of the H08 Squelette to the poetic astronomy of the Slim d’Hermès Lune and the high-tech lightness of the H08 Chronographe, the maison reinforces in 2026 a portfolio that is mature, cohesive, and above all, unmistakably its own.
