MB&F Horological Machine History and References

Origins of the Horological Machine Concept

Which Horological Machine do you own and where does it sit in the MB&F story? Understanding its place among the generations helps you appreciate its design decisions and technical choices.

MB&F was founded in 2005 by Maximilian Büsser with the intention of assembling teams of independent watchmakers, engineers and designers to create radical three-dimensional timepieces. The Horological Machine name first appeared in 2007 with the launch of HM1. Rather than a conventional wristwatch, it presented time through rotating cones and a battle-axe shaped rotor, both visible beneath sapphire crystals. This established the core philosophy that each machine would explore a new way of displaying or interpreting time.

The early machines rejected the round dial entirely. Instead they embraced architectural forms that resembled miniature kinetic sculptures. Every element served both a mechanical and aesthetic purpose. The decision to call them Horological Machines rather than watches signalled that these objects existed outside traditional horological categories. This approach attracted collectors who sought pieces that combined advanced mechanics with narrative-driven design.

Subsequent models built on this foundation while exploring entirely new concepts. Each generation introduced fresh complications or display methods, from dual time zones and moon phases to flying tourbillons and jumping hours. The common thread remained the uncompromising commitment to three-dimensional movement architecture.

Identifying the First Generation: HM1 to HM3

HM1 is recognised by its twin conical displays for hours and minutes, a date window and a power reserve indicator. The case features a distinctive curved profile that sits high on the wrist. Early examples were produced in white gold and rose gold versions. The case was designed by Eric Giroud, while the movement was developed with Peter Speake-Marin and Jean-Marc Wiederrecht.

HM2 followed in 2008 with its biomorphic shape and dual independent time zones shown on separate dials. Its most recognisable trait is the curved sapphire crystal that follows the contours of the titanium or gold case. The piece also introduced a moon phase and a date function arranged in a manner that felt more organic than classical.

HM3, launched in 2009, is perhaps the most iconic early machine. It displays time through two rotating discs, one for hours and one for minutes, read against fixed markers on a raised bridge. A battle-axe shaped rotor is visible from above and appears to float over the movement. Variations include the HM3 Frog, the Starcruiser and the Megawind, offered in different metals and finishes. The specialist checks the case, caseback, engravings and movement to determine precise placement within the HM3 family.

Mid-Period Evolution: HM4 through HM6

HM4 Thunderbolt arrived in 2010 and marked a departure in form. Its elongated case was inspired by aviation and featured time displays at each end connected by a central bridge. The hour and minute pods are read from above, so the watch does not need to be turned on the wrist. Sapphire crystals on multiple planes reveal the intricate gearing. Materials ranged from titanium to rose gold, with selected editions distinguished by their finish.

HM5 adopted a more compact, almost rectangular profile and introduced the perpendicular time display. Its design drew on 1970s inspiration yet remained unmistakably MB&F. The on-demand jumping hours and trailing minutes are viewed through a prism that corrects the image so the numerals appear upright.

HM6 introduced the concept of the space pirate vessel with its central flying tourbillon mounted between two spheres that indicate hours and minutes. The movement appears to hover within the case, supported by intricate bridges. Limited editions explored different finishes and materials, each requiring careful examination of the case shape, sphere design and any unique engravings or markings to determine exact variant.

Later Generations and Technical Ambition

HM7 Aquapod, released in 2017, took the machine into new territory with its rotating bezel that indicates hours and a central minutes hand. The case resembles a jellyfish with undulating sapphire elements. Different versions exist in titanium and rose gold, each with distinct colours and rotor designs. The specialist checks the case, caseback, engravings and movement to confirm the exact variant.

HM8 Mark 2 simplified some elements of the earlier HM8 while retaining the engine block aesthetic. The time is displayed vertically through rotating cones viewed in a mirror. Its more wearable size and cleaner lines distinguish it from the first-generation machines.

HM9 Flow and HM10 Bulldog mark a later chapter in the series. HM9 features a streamlined, automotive-inspired case with dual balances and a central time display. HM10 uses a jumping hours and trailing minutes system within a case that echoes classic car design. Each new model builds on the accumulated knowledge of previous machines while exploring fresh mechanical narratives. Comparing the overall silhouette, the arrangement of indicators and the case materials helps situate any example within the broader timeline.

Comparing References and Generations Side by Side

Early machines such as HM1, HM2 and HM3 tend to have more complex, multi-plane cases with pronounced curves and multiple sapphire crystals. Later pieces such as HM9 and HM10 often adopt more wearable proportions while maintaining mechanical drama. The rotor shape, presence or absence of a tourbillon, and the precise method of time indication provide immediate clues.

Material choices also evolved. Titanium appears frequently across generations for its lightness and strength, while precious metals and special coatings distinguish limited editions. The treatment of the bridges, the colour of the dials or spheres, and any unique engravings on the case or movement plates further differentiate one reference from another. Close inspection of the case, caseback, engravings and movement usually reveals the generation.

Certain signature elements persist. The battle-axe rotor, for instance, appears in several early models, while later machines explore new rotor geometries. By noting the exact layout of the time display, the presence of additional complications such as a power reserve or moon phase, and the overall architectural approach, an owner can accurately place their watch within the twenty-year story.

Assessing Condition and Completeness

The assessment of any Horological Machine focuses on the state of the case surfaces, the clarity of the sapphire crystals and the smooth operation of all functions. Scratches on titanium or gold, clouding within the crystals, or any misalignment in the rotating elements can influence how the piece is received. The movement should be examined for signs of consistent performance, although specialist servicing is best left to qualified technicians after a decision to sell has been made.

Completeness matters. While original boxes and papers are welcomed when available, they are not required to begin the process. The presence of the correct strap or bracelet, any specific tools supplied with the watch, and the overall harmony of the piece contribute to its story. Demand for particular references can vary according to their place in the MB&F narrative, the materials used and the rarity of the specific configuration. Every element is considered together to arrive at a fair and considered view.

Common pitfalls include mistaking later re-editions or colour variants for original releases. Checking serial numbers where present, verifying the exact movement layout against known references, and noting any limited-edition markings prevents confusion. Sending the watch exactly as it is received avoids any risk of accidental damage or loss of original patina that may form part of its character.

Photography Guidance for Accurate Assessment

Clear, well-lit photographs form the essential starting point for any valuation. Capture the watch from multiple angles: front, back, both sides and at an angle that shows the depth of the case and the complexity of the movement beneath the crystals. Include close-ups of the dial or display elements, the crown, the lugs and any engravings. Natural daylight or a soft, even light source reveals true colours and surface condition without harsh reflections.

Photograph the movement through the caseback if visible, ensuring the rotor and bridges are clearly shown. If the watch is on a strap or bracelet, include images of the clasp and how the strap attaches. Take separate shots of any surface marks, however small, so they can be properly accounted for. A simple white or neutral background helps the details stand out. High-resolution files are preferred, though the online form accepts common image formats and allows multiple uploads.

These images allow the team to identify the precise generation and reference, evaluate the overall harmony of the piece and understand any nuances that affect its reception. Good photography protects both parties by ensuring there are no surprises when the watch is inspected in person.
