MB&F Horological Machine N°11

Introduction: A Sphere of Horological Audacity

As a daily-wear watch reviewer for Vivir.com, my mandate is to dissect not just the horological brilliance but the tactile reality of a timepiece on the wrist. When MB&F unveiled the Horological Machine N°11, aptly dubbed 'Architect,' the horological world collectively gasped. It is, by any measure, a radical departure from traditional watchmaking, a kinetic sculpture designed to evoke a miniature, futuristic house.

My task, however, transcends mere admiration of its avant-garde aesthetics. I must ask: how does this architectural marvel survive a real week on the wrist? What does it feel like to wear a spherical titan that rotates on command, revealing not just time but a thermometer and a flying tourbillon in its distinct 'rooms'? This review delves into the HM11's audacious design, its complex mechanics, and critically, its surprising, yet undeniably demanding, wearability.

The Genesis of a Horological Machine: MB&F's Vision

Founded in 2005 by Maximilian Büsser, MB&F (Maximilian Büsser & Friends) is less a watch brand and more a creative laboratory. Their mission is to collaborate with talented 'Friends'—independent watchmakers, designers, and artisans—to create three-dimensional horological machines that challenge conventional notions of timekeeping. Unlike traditional brands that refine existing designs, MB&F consistently reinvents the wheel, or in this case, the sphere.

The 'Horological Machine' series, to which the HM11 belongs, is the purest expression of this philosophy. Each HM is a kinetic sculpture, a fantastical engine designed to inhabit a unique, often sculptural, case. The HM11 'Architect' is a continuation of this legacy, drawing inspiration from modernist architecture and the idea of a living space. It’s a testament to MB&F’s unwavering commitment to pushing the boundaries of what a timepiece can be, transforming it from a simple instrument into a piece of wearable art.

First Impressions & Design Philosophy: A Spherical Statement

Unboxing the HM11 Architect is an event in itself. The watch doesn't just sit there; it presents itself. Its spherical Grade 5 titanium case, with four distinct pods or 'rooms' emanating from its central core, immediately captivates. This isn't a watch you glance at; it's a watch you study, a miniature world on your wrist. The architectural inspiration is palpable – each pod serves a specific function, much like rooms in a house.

The design is a masterclass in three-dimensional horology. The central sphere houses the main movement and the mesmerising flying tourbillon, visible through a large sapphire crystal. The four surrounding pods are dedicated to specific displays: one for hours and minutes, another for the power reserve indicator, a third for a whimsical thermometer, and the fourth, of course, for the crown. The ability to rotate the entire case a full 360 degrees, allowing the wearer to orient the displays as desired, is not just a technical feat but a playful interaction that encourages engagement with the machine. This interactivity is central to MB&F’s ethos, turning passive observation into active participation.

On the Wrist: Wearability & Comfort Redefined

Let's address the elephant in the room – or rather, the sphere on the wrist. With an overall diameter of 46mm (including the pods) and a staggering thickness of 23mm, the HM11 Architect is, without question, a substantial timepiece. It's a watch that demands attention, both from onlookers and from the wearer navigating tight spaces.

However, the genius of its construction lies in its material: Grade 5 titanium. This choice dramatically reduces the overall weight, making the watch surprisingly comfortable despite its volume. Unlike a heavy gold watch of similar dimensions, the HM11 doesn't drag the wrist down. The integrated rubber strap, available in vibrant blue or crisp white, is incredibly supple and contours beautifully, hugging the wrist securely. The deployant clasp is robust and contributes to the watch's overall secure feel.

While it lacks traditional lugs, the four pods effectively create a footprint on the wrist, with an approximate span of 48mm where the strap attaches. This ensures it doesn't feel like a floating orb but rather a well-anchored, albeit tall, presence. Wearing it for a week, I found that while it never disappeared under a cuff (an impossibility), its ergonomic design prevented it from feeling unwieldy. Balance is key here; the weight distribution is excellent, preventing any top-heavy sensation. That said, prepare for frequent encounters with doorframes and desk edges – this is a watch that asserts its presence in every dimension.

The Engine Room: Movement & Complications Unpacked

At the heart of the HM11 Architect lies the bespoke MB&F HM11 engine, a manually wound movement developed specifically for this spherical architecture. It's a testament to the brand's commitment to integrated design, where form and function are inextricably linked. The movement boasts a robust 72-hour power reserve, a respectable figure for a manual-winding calibre, ensuring it will keep ticking through a long weekend.

The frequency is 18,000 vibrations per hour (2.5 Hz), a slower beat rate that allows for a more mesmerising view of the central flying tourbillon. This isn't a high-speed engine; it's a finely tuned, visually captivating mechanism. Comprised of 29 jewels, the calibre is designed with a three-dimensional architecture that complements the watch's external form. The finishing, as expected from MB&F, is exquisite, though much of it is hidden by the case's unique design, with the focus being on the visible tourbillon and the individual displays.

Beyond time, the HM11 offers three compelling complications. The power reserve indicator is intuitive, providing a clear visual cue for when winding is required. The flying tourbillon, suspended elegantly in its own sapphire 'room,' is a constant source of fascination, showcasing the pinnacle of horological artistry. Perhaps the most whimsical complication is the thermometer, a charming nod to the domestic inspiration, reminding the wearer of the ambient temperature – a playful, rather than strictly practical, addition.

Legibility & Practicality: A Different Kind of Read

Legibility on the HM11 is a unique proposition. Unlike a conventional watch with a single dial, the time, power reserve, and thermometer are housed in separate, distinct pods. While each individual display is clear and well-contrasted, reading the time quickly requires a deliberate glance at its dedicated 'room.' The Super-LumiNova application on the hour and minute hands ensures readability in low-light conditions, but again, it’s not a quick-fire glance.

Practicality for a watch of this calibre is always relative. Its water resistance is a modest 20 meters, meaning it's splash-proof but certainly not designed for swimming or even heavy rain. This underscores its role as a luxury art piece rather than a rugged tool watch. The ability to rotate the case is a delightful interaction, allowing the wearer to align the time with their line of sight or simply to admire the tourbillon. While not essential for time-telling, it adds an engaging layer of user experience.

The Collection & Variants: A Limited Architectural Series

The MB&F HM11 'Architect' was launched in two distinct, yet equally striking, variants, each limited to just 25 pieces. Both share the same Grade 5 titanium case, but differ in the accent colours of their 'pods' and integrated rubber straps:

• Reference 61.T.B: Features captivating blue accents on the pods and a matching blue rubber strap, evoking a cool, futuristic aesthetic.
• Reference 61.T.W: Presents with crisp white accents on the pods and a clean white rubber strap, offering a brighter, more minimalist architectural feel.

These limited editions ensure the HM11 remains an exclusive possession for a select few collectors worldwide.

Family Connections & Brand Lineage

The HM11 stands proudly within the lineage of MB&F's 'Horological Machine' series, a collection known for its audacious designs and groundbreaking mechanics. It follows in the footsteps of iconic models like the HM1 (the brand's inaugural piece), the space-inspired HM6 'Space Pirate,' and the automotive-inspired HM8 and HM9 'Flow.' Each Horological Machine is a distinct chapter in MB&F's narrative of mechanical artistry, pushing the boundaries of what a wristwatch can be.

Beyond the Horological Machines, MB&F also offers the 'Legacy Machine' collection, which, while equally complex and innovative, presents a more classical aesthetic. Notable models include the Legacy Machine No.1, the Legacy Machine Perpetual, and the captivating Legacy Machine FlyingT, each showcasing traditional haute horlogerie finishing within MB&F's unique vision.

Beyond the Horizon: Similar Philosophies

While truly direct comparisons are challenging given MB&F's unique niche, collectors who appreciate the HM11's avant-garde approach to timekeeping and its sculptural presence might also find themselves drawn to brands like Urwerk, with models such as the UR-100V, which shares a similar futuristic aesthetic and innovative time display. De Bethune, with its sculptural movements and unique case designs like the DB28, also appeals to those seeking horological art. And for sheer high-tech, performance-oriented extremity, Richard Mille, exemplified by models like the RM 011, often resonates with the same discerning collectors who value groundbreaking materials and audacious design.

Investment & Ownership: A Collector's Perspective

Priced at an MSRP of $220,000 USD, the MB&F HM11 Architect firmly positions itself in the upper echelons of luxury independent watchmaking. For a piece of this complexity, limited production, and artistic merit, the price point is commensurate with its unique proposition. As a recent release, its current retail pricing remains consistent with its launch price, reflecting its exclusivity.

In the secondary market, given its newness and extreme rarity (only 50 pieces total), pre-owned examples are likely to command prices within the $200,000-$250,000 range, potentially higher depending on condition and demand. The trend for MB&F pieces, especially limited-edition Horological Machines, has historically been one of appreciation or stable value retention, making the HM11 a strong contender for an investment piece, provided one views it through the lens of collectible art.

My hold recommendation for a sophisticated collector is strong: a unique, highly limited-production piece from a respected independent brand like MB&F is likely to hold or even increase its value over time, especially given its architectural theme and mechanical innovation. There is no major auction history for the HM11 yet, as it is a very recent release, but future auctions will undoubtedly see intense bidding for these rare machines.

The Cost of Exclusivity: Service & Maintenance

Ownership of an MB&F timepiece comes with the understanding that maintenance is a specialized affair. The recommended service interval for the HM11 is approximately 5 years, consistent with most high-end mechanical watches. However, the approximate cost of servicing, around $2,500 USD, reflects the complexity of the movement and the specialized expertise required. Servicing is exclusively available through authorized MB&F service centers, as the intricate mechanics and unique construction demand specific tools and knowledge. This ensures the longevity and optimal performance of your horological machine.
