Introducing The New Louis Erard x Vianney Halter Futur Antérieur

Louis Erard and Vianney Halter have done something quietly audacious: they have taken the most recognizable idea in Halter’s universe: the riveted, porthole-like architecture of the Antiqua, and rebuilt it as an entirely new watch. The result is the Futur Antérieur, offered in Gold and Silver editions, each carrying not one but two automatic movements beneath two separate dials.

The name is a grammatical pun with real emotional weight. In French, the futur antérieur describes an action that will have happened by a future point in time. It is an unusually precise title for a collaboration between two watchmakers who already share a history and who have now chosen to make something that feels simultaneously archaeological and futuristic.

A collaboration with a past

Louis Erard and Vianney Halter first joined forces in 2020, beginning a partnership that has become one of the more intellectually coherent recurring dialogues in contemporary watchmaking. Louis Erard, founded in 1929 in the Swiss Jura, has built its modern identity around accessible mechanical craft, distinctive regulators, and collaborations with unconventional creators including Alain Silberstein, Konstantin Chaykin, and Halter.

Halter, meanwhile, needs little introduction among collectors. An independent watchmaker since 1984, the French-born, Switzerland-based Halter has long occupied a rare position in horology: part engineer, part dreamer, and entirely resistant to convention. His Antiqua, with its riveted bezels and multiple displays, remains one of the defining independent watches of the past three decades, an object that seems to have arrived from a future imagined by Jules Verne.

Their earlier Louis Erard collaborations translated Halter’s visual language into the accessible framework of Louis Erard’s regulator platform. The new Futur Antérieur goes much further. The intention with this latest project is not merely to place two names on a dial, but to create something that could not have existed without both parties.

The Antiqua, through two portholes

At first glance, the Futur Antérieur is unmistakably Halter. Two raised, riveted bezels dominate the dial side, framing two circular displays like windows into separate mechanical worlds. One aperture carries the hours and minutes, the other, a central seconds hand. Each is powered by its own automatic movement.

That dual-movement construction is the watch’s central mechanical conceit. Rather than using a single caliber to drive two displays, Louis Erard has fitted two Sellita SW100 automatic movements side by side, one configured for hours and minutes, the other for seconds. Each measures 17.20 mm in diameter and 4.80 mm in thickness, contains 25 jewels, beats at 28,800 vph, and offers a power reserve of approximately 42 hours.

On the new collaborative product, two raised, riveted bezels frame two entirely separate dials.

It is a deliberately theatrical solution. The seconds are not merely a subsidiary function, they inhabit their own chamber, with their own crystal, crown, movement, and visual rhythm. The effect is less like a conventional watch dial and more like a miniature instrument panel: two synchronized but independent mechanical observations of time.

A new case, built for obsession

The Futur Antérieur is also significant for what Louis Erard has never done before. The stainless-steel case is an entirely new construction, assembled from 67 components, yet it retains a remarkably slim profile of just 8.85 mm. Its dimensions are 38 mm by 44 mm, with 20 mm lug width and water resistance of 5 bar, or 50 meters.

That slimness matters. A watch with two raised bezels, two sapphire crystals, two crowns, and two movements could easily have become bulky and overwrought. Instead, the case keeps the sculpture close to the wrist, preserving wearability without surrendering the dramatic presence that makes the design compelling.

The finishing is unusually layered for a watch at this price with brushed and polished surfaces. Each bezel carries 12 polished yellow-gilt rivets, while each of the two Vianney Halter signature crowns is set with six more. The dials themselves combine grained baseplates with circular-brushed applied outer rings and polished chamfers.

Gold and Silver: two temperaments

Louis Erard presents the Futur Antérieur in two editions, each limited to 178 pieces, the brand’s signature number for collaborations.

For collectors unable, or unwilling, to choose, Louis Erard will offer a Duo Set of 78 examples, pairing the Gold and Silver references in a wooden box. The set is priced at CHF 9,900.

Why this watch matters

The Futur Antérieur succeeds because it avoids the most common failure of celebrity-designer collaborations: borrowing a signature without understanding its meaning. Halter’s Antiqua is not simply about rivets or multiple dials. It is about the romance of mechanical construction, about making timekeeping feel like an engineered object from an alternate history.

Louis Erard has understood that. The two movements, two crystals, two crowns, and two display apertures are not gimmicks, they are the conceptual engine of the watch. They make the Antiqua’s visual language functional, giving the design a reason to exist beyond nostalgia.
