A New Chapter in the Slim d’Hermès Story

In 2026, Hermès turns its creative attention to the art of skeletonisation across three distinct watch lines, and the Slim d’Hermès Squelette Lune sits at the collection’s most poetic extreme. Where many skeleton watches celebrate mechanical complexity through density, this piece pursues the opposite — openness, lightness, and the quiet drama of a lunar complication suspended within a barely-there movement. The result is a timepiece that invites contemplation rather than demanding admiration. You can explore the broader context of Hermès’s 2026 output at Watches and Wonders, where the collection made its debut.

At 39.5 mm in diameter, the case strikes a balance between presence and refinement. Two material paths define the offering: a satin-brushed DLC-treated titanium case paired with an anthracite DLC-treated titanium bezel, and a polished 950 platinum case with a matching polished bezel. The former carries a distinctly contemporary edge; the latter speaks an older, more classical horological language. Both are water-resistant to 3 bar and fitted with anti-glare sapphire crystal and a sapphire caseback that fully exposes the movement beneath.

The H1953 Movement — Colour as Architecture

The Manufacture Hermès H1953 calibre is, by any measure, an accomplishment in miniaturisation. At just 3.57 mm thick and 30 mm in diameter, it qualifies as a genuine extra-thin movement, yet accommodates 178 components and 29 jewels without visual crowding. The mechanical self-winding system operates via a micro-rotor, keeping the movement profile as slim as possible while preserving wearability. Beating at 21,600 vibrations per hour and delivering a 48-hour power reserve, the H1953 is designed and crafted in Switzerland.

What makes the H1953 immediately distinctive is its use of colour as a structural element rather than mere decoration. In the vert d’eau version, the bridges and mainplate carry that characteristic pale aqua tone throughout — visible through the openworked black gold dial above. The blue version follows the same principle with equal conviction. Hand-chamfered and bead-blasted bridges catch and scatter light differently depending on angle and ambient conditions, ensuring the watch reads differently across morning, noon, and evening light — a quality that rewards long-term ownership.

The Double Moon Phase — Science and Symbolism

The complication at 6:00 is the watch’s defining gesture. A double moon phase display tracks the lunar cycle as seen simultaneously from the Northern and Southern hemispheres — a technically demanding function that also carries genuine poetic weight. For a collector who travels between continents, the display remains relevant regardless of latitude. Hermès frames this not as a technical exercise but as an invitation: to follow time as it moves across the sky, to observe cycles rather than simply read minutes.

The functions are deliberately edited: hours, minutes, and the double moon phase at 6:00. Nothing else competes for attention. Rhodium-plated baton-type hands read cleanly against the openworked dial, while a white transfer-printed minutes track provides the only conventional reference point. This restraint is characteristic of Hermès’s approach to complication — the brand adds only what genuinely enriches the wearing experience, then removes everything that doesn’t. The official Hermès website provides further context on the Slim d’Hermès collection’s place within the maison’s broader creative vision.

Straps, Clasps, and the Question of Wearability

The Slim d’Hermès Squelette Lune is offered with straps across two groups. The titanium version pairs with matt gris étain alligator, matt black alligator, or black Barénia calfskin. The platinum variant adds matt bleu abysse alligator and bleu navy Swift calfskin to the matt black alligator option. Each strap connects via a folding clasp — in titanium or white gold, at 17 mm — that disappears on the wrist rather than drawing attention away from the case and dial. At 39.5 mm, the watch wears comfortably on a range of wrist sizes, and the slim movement profile ensures it sits low and close to the skin.

Why It Matters

The Slim d’Hermès Squelette Lune is a precise argument for restraint in haute horlogerie. By pairing an ultra-thin double moon phase movement with colour-coded architecture and a meticulously edited dial, Hermès demonstrates that complexity need not mean density. For collectors in the GCC who prize originality alongside craftsmanship, the two expressions — vert d’eau and blue — offer a genuinely distinctive entry into one of watchmaking’s most demanding creative disciplines.
