# MB&F HM7 Aquapod Review – The Jellyfish‑Inspired Horological Machine The MB&F HM7 Aquapod arrives like a living organism on the wrist: a round, 53.8 mm sapphire‑capped sphere that houses a flying tourbillon, a tentacle‑like winding rotor and a floating bezel that seems to orbit the whole piece. Unveiled at SIHH 2017, this is the brand’s first foray into an aquatic theme, and it pushes the “Horological Machine” concept into three‑dimensional territory that feels more like a work of kinetic sculpture than a conventional sports watch. In the following 1,500‑plus words we’ll dissect its heritage, design, movement, wearability, appropriate occasions, and finally ask whether the six‑figure price tag is justified. --- ## Heritage — the model's place in the brand's line and its launch context When MB&F introduced the HM7 Aquapod at the Salon International de la Haute Horlogerie (SIHH) in 2017, the Swiss independent watchmaker was already known for turning avant‑garde engineering into wearable art. The “HM” (Horological Machine) line began with the HM1 “Flying Saucer” in 2005 and has since evolved through increasingly audacious concepts: the HM4 “Thunderbird” (a mechanical airplane), the HM5 “Cactus” (a desert‑inspired chronograph), and the HM6 “Time Cube” (a three‑dimensional perpetual calendar). The HM7 marks a thematic pivot from sky‑bound machines to the depths, positioning itself as MB&F’s first “aquatic” creation. The SIHH debut was deliberate. By choosing the industry’s premier showcase for high‑horology rather than BaselWorld, MB&F signaled that the Aquapod was meant to be seen alongside the most technically daring pieces of the season, not merely as a novelty at a trade fair. Its limited production—33 titanium pieces and 66 in 18 k red gold—reinforces its status as a collector’s item rather than a mass‑market sports watch. In the brand’s hierarchy, the HM7 sits at the top tier (Tier 1), sharing the same pricing philosophy as other flagship HMs while exploring a new aesthetic vocabulary inspired by marine life. --- ## Design & Case — case dimensions, materials, dial ### Size and Form At 53.8 mm in diameter and roughly 21.3 mm thick, the Aquapod is unmistakably large. The spherical case is the first round‑cased HM, a departure from the more angular or irregular silhouettes of its predecessors. Its diameter is comparable to a small pocket watch, and the thickness is dictated by the three‑dimensional arrangement of the movement’s components. The case is crafted from either grade‑5 titanium or 18 k red gold, each finished to a high polish that catches light in a way that mimics the iridescence of a jellyfish’s bell. ### Sapphire Crystal Elements Sources describe the case as “spherical … with sapphire crystals.” While it would be inaccurate to claim the entire sphere is wrapped in sapphire, the watch does feature sapphire crystal on the front and on the side “windows” that expose the floating bezel and the winding rotor. These crystal elements give the Aquapod an almost aquarium‑like transparency, allowing the wearer to observe the concentric rotation of the rotor, the tourbillon, and the unidirectional bezel that appears to orbit the central axis. ### Dial and Indicators The dial itself is a minimalist black canvas punctuated by a single luminous marker—a bright blue “martini‑glass” shape on the titanium version (the red‑gold model uses a similar hue). Super‑LumiNova and AGT lume bathe the marker and the hour‑hand in a subtle glow after dark, reinforcing the aquatic theme. The floating bezel, made of a thin sapphire ring, is unidirectional and rotates independently, reminiscent of Saturn’s rings or a jellyfish’s tentacles drifting in water. The central flying tourbillon sits at the 12 o’clock position, its cage visible through the crystal dome. ### Materials and Finishes Titanium offers a lightweight, matte‑to‑polished finish that reduces the overall heft despite the watch’s size, while the red‑gold version adds a warm, luxurious heft that emphasizes its status as a high‑end collector’s piece. Both versions share the same sapphire‑crystal treatment and the same internal architecture, making the choice essentially a matter of personal aesthetic preference. --- ## Movement & Performance — caliber, power reserve, accuracy Inside the Aquapod beats MB&F’s in‑house automatic caliber, a marvel of compact engineering that houses a central flying tourbillon. The tourbillon rotates around a vertical axis, a nod to the watch’s three‑dimensional ethos and a visual centerpiece that draws the eye upward through the crystal dome. The movement also incorporates a “tentacle‑like” winding rotor at the base of the sphere; unlike traditional rotors, this piece resembles a jellyfish’s oral arms and rotates concentrically with the rest of the mechanism. Key specifications: | Spec | Detail | |------|--------| | **Movement** | Automatic, in‑house, central flying tourbillon | | **Power reserve** | 72 hours | | **Water resistance** | 50 m (5 atm) | | **Frequency** | Not explicitly stated in sources (typical MB&F automatic rates are 28,800 vph) | | **Accuracy** | No COSC certification disclosed; MB&F typically relies on in‑house regulation | The 72‑hour power reserve is generous for a watch of this size, especially given the energy demands of a flying tourbillon and the rotating bezel. However, the 50 m water resistance—equivalent to a shallow dive—means the Aquapod is more a “water‑friendly” piece than a true dive watch. MB&F themselves note that “HM7 is not a diving watch,” underscoring that the water resistance is more a design statement than a functional requirement. Because MB&F does not publicly provide COSC certification for the HM7, we must rely on the brand’s reputation for fine regulation. In practice, owners report a respectable day‑to‑day accuracy, though the complex layout may require more frequent servicing than a conventional three‑hand chronometer. --- ## On the Wrist — wearability, lug‑to‑lug, comfort notes Putting a 53.8 mm sphere on the wrist is an experience that borders on performance art. The lug‑to‑lug spread is essentially the case’s full diameter, meaning the watch sits almost directly on the skin without the usual overhang of a traditional bracelet. MB&F equips the Aquapod with a custom‑engineered bracelet that curves around the wrist, using either titanium or red‑gold links that match the case material. The bracelet’s curvature helps distribute the watch’s weight, but the overall feel remains substantial—roughly 120 g in titanium, a bit heavier in red gold. The spherical shape creates a unique ergonomics challenge: the watch can roll slightly on the wrist if not secured tightly, and the large surface area may feel intrusive under a shirt cuff. Nevertheless, the internal cushioning of the bracelet’s inner links, combined with the smooth sapphire crystal, provides a surprisingly comfortable wear once the piece is properly adjusted. The watch’s thickness (≈21 mm) means it sits prominently, making it difficult to conceal under a shirt cuff—a factor to consider for those who need a discreet profile. Thermal expansion is negligible thanks to the titanium’s low coefficient of expansion, but the red‑gold version can feel warmer on the skin in hot climates. The bright blue “martini‑glass” marker, while visually striking, can be a point of visual distraction for some wearers, especially in low‑light environments where it glows more intensely than the surrounding lume. --- ## When to Wear — occasion, setting and dress‑code fit The HM7 Aquapod is a statement piece that thrives in environments where avant‑garde design is celebrated. Its size, price, and sculptural nature make it a perfect fit for: * **High‑profile events** – gala evenings, art openings, and red‑carpet appearances where a conversation‑starter is welcome. * **Private collections and watch‑shows** – as a centerpiece among other horological machines, its uniqueness shines. * **Creative industry gatherings** – fashion shoots, design conferences, or tech‑forward festivals where the blend of art and engineering resonates. Conversely, the Aquapod is less suited for: * **Formal business settings** – the watch’s size and flamboyance can clash with a classic suit and tie. * **Active sports or diving** – the 50 m water resistance and bulky profile make it impractical for genuine underwater activities. * **Everyday casual wear** – while the titanium version is lighter, the watch’s silhouette still draws attention, potentially feeling out of place in a low‑key café or office. In short, think of the Aquapod as a “watch‑as‑art” piece meant to be displayed on the wrist during moments when you want to be noticed, rather than a utilitarian timekeeper for daily chores. --- ## Value & Verdict — price‑positioning + final take **Price** – The Aquapod is priced at $97,150 for the grade‑5 titanium version and $116,950 for the 18 k red‑gold edition. These figures place it firmly in the six‑figure tier, aligning with MB&F’s flagship Horological Machines. The limited production (33 titanium, 66 red gold) adds scarcity value, and the bespoke engineering justifies a premium beyond typical luxury sports watches. **Strengths** * **Innovative three‑dimensional design** – The spherical case, floating bezel, and visible rotating rotor create a visual experience rarely seen in watchmaking. * **Technical prowess** – An in‑house automatic movement with a central flying tourbillon and 72‑hour power reserve showcases MB&F’s engineering capabilities. * **Material quality** – Titanium and red gold cases are expertly finished, and the sapphire crystal elements provide a clear view of the mechanics. * **Collectibility** – Limited numbers and the brand’s reputation for iconic HMs make the Aquapod a likely future collector’s item. **Weaknesses** * **Size and wearability** – At 53.8 mm and 21 mm thick, the watch can feel cumbersome for many wrists. * **Water resistance** – 50 m is modest for a “aquatic” watch and precludes genuine diving. * **Aesthetic quirks** – The bright blue martini‑glass marker may feel out of place to purists. * **Service considerations** – The complex architecture may demand more frequent, and expensive, maintenance than a conventional chronometer. **Verdict** The MB&F HM7 Aquapod is less a conventional sports watch and more a kinetic sculpture that pushes the boundaries of what a time‑telling device can look like. Its launch at SIHH 2017 signaled a bold new direction for MB&F, and the watch delivers on that promise with a blend of artistic daring and mechanical sophistication. For collectors who value uniqueness, are comfortable with a six‑figure investment, and appreciate a piece that doubles as a conversation‑starter, the Aquapod is a compelling acquisition. For those seeking a practical, understated sports watch, the HM7 will feel more like a museum exhibit than a functional tool. In the end, the HM7 Aquapod lives up to its jellyfish inspiration: it drifts gracefully on the wrist, its luminous tentacles turning in silent harmony, reminding us that haute horology can be as much about visual poetry as it is about precision. If you can accommodate its size, price, and limited water resistance, the Aquapod is a bold, technically impressive addition to any serious watch collection.
