Maison Alcée x MB&F Nostromo Hands-On: 222 Parts, Three Feet, and Ten Hours at the Bench

By Brent Robillard

Designed by MB&F’s Maximilian Maertens and delivered as a 222-component kit, the Nostromo turns a desk clock into ten hours at the watchmaker’s bench.

First contact

Buying the Maison Alcée x MB&F Nostromo starts a ten-hour appointment with 222 components. The completed clock has an alien profile, a peacock-blue dial, and three legs that look ready to carry it across the desk. But before any of that can happen, its owner has to build it.

I met the Nostromo at M.A.D.Gallery Geneva on September 1. M.A.D.Gallery was the first retailer to support Maison Alcée, and this clock was created for the gallery’s 15th anniversary. It also gave me the useful, slightly strange opportunity to meet the finished creature before imagining what it would be like to assemble one myself.

To begin, it was smaller than I imagined it would be. This is a good thing. I wondered, prior to seeing it, where in my home I would keep such an item. But it really would not look out of place on my work desk. And it would certainly transform the space. The first detail that captured my attention was the blue dial arc and then the exposed train. The press photos had prepared me for the experience, but not for the curiosity it would evoke.

A clock with assembly required

Maison Alcée was founded in 2021 by Alcée and Benoît Montfort. Its first clock, the Persée, arrives as a kit with 233 components, tools, and a 250-page illustrated instruction book. QR codes connect the owner to video guidance, while a private discussion group provides another layer of support. Some of the tools use beryllium-copper parts to reduce the chance of scratching components. This is careful hand-holding for a serious project, rather than a simplified model with a mechanical movement hidden inside.

I heard the broader philosophy behind the project from Alcée herself when we met in the salon of a home just around the corner from M.A.D.Gallery. She explained that Maison Alcée was founded to revive interest in clockmaking and watchmaking through education. The idea is rooted partly in her own childhood, when she loved building with Meccano and LEGO. Nostromo and Persée translate that instinct into horology, allowing owners to understand a mechanical movement by assembling one with their own hands.

Alcée also hopes the process will persuade people to step away from the pace of everyday life and spend meaningful time on something demanding patience and concentration. Ideally, that experience can be shared. She told us about a busy CEO who assembled one of the clocks with his son, the project giving them an opportunity to reconnect over the hours they spent together. It is a fitting story for an object built to measure time: the clock records its passage only after encouraging its owners to become more conscious of how they spend it.

The idea earned Maison Alcée the Audacity Prize at the 2023 Grand Prix d’Horlogerie de Genève. It also explains the appeal to M.A.D.Gallery. MB&F has spent years placing clocks, kinetic objects, and horological machines in the same room. The Nostromo adds participation to that mixture: the collector supplies the assembly labour and learns how the mechanism goes together along the way.

Partners in mechanical play

The collaboration was designed by MB&F Creative Designer Maximilian Maertens and engineered for owner assembly by Maison Alcée. Maertens is an admirer of H.R. Giger, and the references are explicit. The three organic feet, exposed structure, and skeletal profile belong to the visual language of science fiction. The name comes from the commercial spacecraft in Ridley Scott’s original Alien film.

There is also a familiar MB&F habit at work here: a mechanical object is treated like a character. The Calibrated Wrist has previously looked at the automotive version of that idea in the MB&F HM8 Mark 2. Nostromo swaps bodywork for a visible gear train and insect-like stance, but the same affection for machines with personalities remains.

Nostromo, sideways

The basic movement architecture is derived from a wristwatch and enlarged to clock scale. Maertens then turned it on its side and tilted the time display upwards. The clock rests on three feet and can rotate on them, giving the owner a way to alter the viewing angle after assembly. It measures 160mm by 135mm by 123mm and weighs 760g, so this is a compact desk object rather than a mantle clock.

The separated dial segments are finished in M.A.D.Gallery’s peacock blue, a colour repeated in the decorative wall orb used in MB&F spaces. Breaking the dial into an arc opens the view across the wheels beneath it. Black hands provide contrast against the steel and brass mechanism. On the right, the regulating organ appears almost suspended within the frame; on the left, the springs and barrels balance the composition.

Ten hours and 222 parts

Nostromo shows hours, minutes, and seconds, and its hour chime can be switched on or off. A full wind provides 14 days of running time. Maison Alcée estimates that a novice can complete the assembly in about ten hours. Only the regulating organ arrives pre-assembled, leaving the owner to install the gears, wheels, pinions, dial parts, and much of the supporting structure.

The kit includes professional tools and a 250-page illustrated manual with QR-linked videos prepared specifically for the Nostromo. That book may be the most important component in the box. A 222-part mechanism creates plenty of opportunities for hesitation, and the project has to teach sequence, handling, and diagnosis without a watchmaker standing beside the bench. The finished clock records the result, but the real test of Maison Alcée’s work is whether those ten hours remain absorbing when a wheel refuses to sit where the drawing says it should.

Final thoughts

Maison Alcée charges the owner with the work that creates the closest relationship to the object. MB&F supplies a design with enough humour and oddness to make the completed mechanism worth leaving in full view. Nostromo should appeal most to the collector who wants to understand a wheel train with their fingertips, and who will accept a little anxiety as part of the pleasure.
