The 2026 Vault Release Limited Return // Bounded Horizon

The Return of the "Twin Form" Axis

In 2014, to honor our half-century Golden Jubilee milestone, the Maison debuted a design silhouette that altered our archival landscape forever: the platinum "Twin Form." Produced as an absolute singular tier of fifty configurations, the works instantly vanished into private archives.

Over the subsequent decade, a quiet but persistent whisper among institutional collectors has requested its resurrection. This year, the house answers. While the initial dense platinum architecture remains safely retired inside our historic vault, our ateliers have authorized a secondary, strictly bounded series of fifty sibling allocations executed in high-density White Gold.

To distinguish this modern era, the white gold variant holds an absolute privilege: an internally flawless, vibrant pink micro-diamond hidden entirely within the interior wall—visible strictly to the bearer as a quiet, sacred devotion.

Savoir-Faire

Behind each graphic silhouette lies generations of refined French setting techniques. Our master artisans spend upwards of eighty hours on a singular form, achieving a symmetry so seamless it mirrors the laws of nature.

We do not produce to fulfill trends; we create legacy properties designed to outlast generations.

Beyond the Jewel — Object Commissions Since 1974

The Applied Registry

A decade into the Maison, a patron arrived with a request that fit no catalogue: not a ring, but a case he already owned, asking that our hand be applied to it. We accepted. Since then, the request has widened in every direction it could — a walking stick, a private aircraft cabin, occasionally a limited run made alongside a house entirely outside jewelry. The rule has stayed narrow even as the objects have not: we set, engrave, and finish whatever a hand meets or an eye sees. What makes the object work — its engine, its circuitry, its mechanism — remains exactly as its own maker built it.

Ref. 74/01

The First Case

18k Yellow Gold · Hand-Engraved

Our first commission outside the jewel box: a monogrammed cigarette case for a patron who refused to carry anything unconsidered.

Ref. 91/06

The Recased Movement

Platinum · Client's Own Movement

A treasured wristwatch, its movement decades old, is freed from its original case and reset entirely in one made for it alone.

Ref. 08/03

The Device Frame

White Gold · Diamond-Dust Finish

A telephone's outer casing and controls, remade by hand — never the circuitry inside, which stays exactly as its maker intended.

Ref. 15/09

The Walking Stick

Sterling Silver Handle & Ferrule

Not every request arrives grand. A stick carried daily for forty years returns to us simply to be made worthy of the hand that holds it.

Ref. 19/11

The Coachwork Detail

Rose Gold-Plated Trim · Private Commission

Interior trim and badging for a single private motorcar, fitted by our ateliers rather than the manufacturer's own.

Ref. 22/04

The Cabin Commission

18k Rose Gold Hardware & Inlay

Door handles, seatbelt fittings, the smallest touchpoints of a private aircraft cabin, set the same way as a bracelet clasp. The airframe itself is never ours to open.

Ref. 23/07

The Collaboration Capsule

Limited Edition · Co-Signed

Occasionally a house outside jewelry entirely — a sportswear or outerwear label — asks us to sit alongside their name on a capsule run. We accept rarely, and only where a jewel earns its place on the piece.
