The R9's quiet authority doesn't come from any single tone — it comes from the way three of them sit together, with a fourth held in reserve for the parts that count most. Gold at the hub and across the propeller blades. Copper through the connecting links. Silver down the eighteen push-rods and across the valve caps. And, under the heads, a quiet silver-gold alloy on the pistons themselves — a finish that catches the light from one angle and disappears from another. Every surface is hand-finished in our Miami atelier and held to a single standard: built once, perfected once.
The propeller hub, the bullet cone, and the three propeller blades — finished in a warm gold tone, hand-polished one piece at a time. The lustre catches the light from every angle, and the propeller becomes the optical centre of the object. The first thing the eye finds.
Polished · WarmEighteen connecting links and rocker arms — finished in copper, hand-textured to read like forged metal at scale. Each link is seated and aligned by hand. No two sit exactly the same way. None are meant to.
Hand-textured · IndustrialEighteen push-rods run from the crankcase out to the cylinder heads — two per cylinder — finished in a cool, brushed silver, together with the valve caps that crown each head. Inside each cylinder, the pistons themselves carry a subtle silver-gold alloy finish. Cool against the warmth of the gold and copper above.
Brushed · Cool · Alloyed
Gold above. Copper between. Silver down the spine. Alloy at the heart.
From across the room, the R9 reads as a single object.
Up close, every tone speaks for itself.
Each Aero Mécanique R9 passes through over fifty hours of studio work — production, multi-stage hand-painting, controlled curing, individual assembly, and final inspection. There is no production line. Every unit is built one at a time at our Miami atelier.
The result is a precision object — a 9-cylinder radial engine arranged in star configuration, finished with a gold-toned hub and propeller, copper-toned connecting links, eighteen brushed-silver push-rods and valve caps, and silver-gold alloy pistons. Set on a carbon-textured composite base. Hoffmann Atelier produces, finishes, numbers, and certifies every unit personally.
The Aero Mécanique R9 — essentials
The full Hoffmann Atelier experience
Both editions share the same hand-finished precision object, the same laser-engraved certificate, and the same technical blueprint. The Collector’s Edition adds the gallery display case — hand-finished wood base with acrylic vitrine cover — and coordinated delivery with founder updates at each stage. Open production — each piece is sequentially numbered, signed by the founder, and registered in the atelier archive. Production is paced by hand, not by quota.
Every unit receives a multi-coat hand-painted finish, individually cured and inspected. The surface treatment is what separates a Hoffmann Atelier piece from any production replica.
Production is paced by hand, not by quota. Each unit is sequentially numbered, signed by the founder, and registered for life in the atelier archive — your number is yours alone.
Every Aero Mécanique R9 ships with a numbered Certificate of Authenticity, signed by Alain Hoffmann. Both editions include a laser-engraved technical blueprint on plywood.
Gold-toned hub and blades, copper-toned links, brushed-silver push-rods, silver-gold alloy pistons. Four tones, each hand-finished by the master craftsman. Built to be passed down.
Both editions ship inside the Sashimono crate. The Collector's Edition adds a gallery display case — hand-finished wood base, acrylic vitrine cover — not included with the Standard Edition.
One year on manufacturing defects of finish, assembly, and structural components — including base integrity. Direct atelier support, no intermediaries. Excludes user-caused wear and natural patina of the metallic tones.
Every dimension calculated. Every tolerance verified. Hoffmann Atelier production specifications.
"Some objects must be made by hand to be made at all."
The Aero Mécanique R9 is one of these. Each is built in the atelier in Miami — slowly, in sequence, by a single pair of hands. Fifty hours per piece. Ninety-three components. Nine cylinders, three blades, one signature.
I began this atelier for a quiet reason: there is a kind of authority that only an object built carefully — by someone who knew where it was going — can carry. It cannot be hurried, cannot be scaled, cannot be borrowed. It can only be earned, fifty hours at a time, by hands that care where the piece ends up.
When yours leaves the atelier, it carries its number, its signature, and its place in the ledger — which now belongs to you, for as long as the object exists.
There are still some things made this way.
Welcome.
Hoffmann Atelier
When yours leaves the atelier, it carries a number assigned to no one else, a signature in the founder's own hand, and a permanent entry in the archive. Paced by hand, not by quota.
Numbered, atelier-certified pieces are final sale — with one exception: a 14-day exchange window for shipping damage, with photographic evidence and unopened presentation packaging. Every unit ships fully insured via tracked, signature-required carrier. Continental U.S.: insured shipping included (7–10 business days). Hawaii, Alaska & international: shipping quoted separately and settled by the acquirer (7–14 business days); customs, import duties and carrier fees are the acquirer’s responsibility.
