MB&F Horological Machine Condition and Care

The History Behind MB&F Horological Machines

The belief that only flawless MB&F Horological Machines attract serious interest is a common myth. In reality, honest assessment of each piece’s individual history and condition leads to fair and transparent outcomes.

Maximilian Büsser founded MB&F in 2005 after leaving the traditional watch industry with a clear vision: to create horological machines rather than conventional watches. The first Horological Machine, HM1, appeared in 2007 and immediately established a new genre. Its movement was presented as the centrepiece of an object that resembled a futuristic spacecraft more than a wristwatch, with twin balance wheels and a jumping-hours display arranged in a highly three-dimensional layout.

Subsequent models expanded this philosophy. HM2 introduced a moon-phase complication within an even more sculptural case than the HM1. HM3 brought biomorphic curves reminiscent of a frog, with its time displays on raised pods. HM4 took inspiration from aviation, shaped like a jet engine and worn along the wrist. Later pieces such as HM6, HM7 and HM9 continued to push boundaries, with spaceship, aquatic and flowing case designs that blur the line between mechanical engineering and kinetic art.

Each Horological Machine is developed in close collaboration with independent watchmakers, case designers and artisans. Production is deliberately limited, often to small series per reference, using materials chosen for both technical performance and visual impact. Titanium is frequently employed for its lightness and strength, while precious metals add weight and warmth. The design story of every model is therefore inseparable from its physical construction, which is why understanding the history helps when evaluating condition and originality.

Because these objects are conceived as limited-edition works of horological art, their long-term appeal rests on preserving the integrity of the original vision. Any assessment therefore considers not only mechanical soundness but also how closely the piece retains the crispness and presence intended by its creators.

Identifying Your Specific Horological Machine Generation

Horological Machines are primarily identified by their HM designation followed by any edition suffix. Within each family there can be several evolutions. For example, HM1 editions differ mainly in case metal, surface finish and limited-edition detailing rather than in a wholly redesigned architecture. Similar edition differences exist across the HM3, HM4 and HM6 families.

To identify your piece accurately, examine the overall silhouette from above and from the side. Note the precise layout of the time-telling elements, whether the hours are shown on rotating discs, cones or other indications, and how the minutes are displayed. The shape and finish of the crown or pushers can also distinguish one generation from another. The specialist checks the case, caseback, engravings and movement.

Material choice is another identifier. Certain editions were offered only in grade-5 titanium, others exclusively in 18-carat rose gold, while some combined metals or introduced new surface treatments. Comparing the visible architecture and any markings against documented examples from each series prevents confusion between closely related models.

High-resolution photographs taken in even lighting from every angle, including direct overhead, profile, caseback, crystal edges and any bracelet or strap, allow specialists to confirm the exact version. This step is essential because subtle differences between generations influence how condition is weighed during assessment.

Key Condition Factors That Matter in Assessment

The case edges receive particular attention because they define the architectural sharpness that characterises every Horological Machine. Rounded or softened bevels often indicate previous polishing, which can diminish the intended geometry of the design. Light surface scratches consistent with careful ownership are accepted as part of the piece’s story, whereas deep gouges or uneven wear require careful evaluation.

Crystal condition is critical given the large, multifaceted sapphire components used across the range. Fine hairlines may be inevitable over time, but chips, haze or deep scratches that interfere with reading the displays affect both aesthetics and perceived care. Because many models feature domed or angled crystals positioned above complex indications, even minor imperfections become visually prominent under normal lighting.

Dials, hands and three-dimensional indications must be examined for consistency of colour, alignment and surface quality. Discolouration of lacquered or plated elements, fading of any applied markers or misalignment of rotating discs can detract from the overall harmony. The intricate nature of these displays means that small flaws are more noticeable than on a traditional dial.

Functional aspects are assessed where possible without disassembly. Smooth winding, correct operation of any setting mechanisms and the reliable movement of jumping hours, rotating discs or other signature complications are noted. Full testing and regulation occur only after the piece has been received and inspected in the workshop.

Bracelet or strap condition forms another important part of the evaluation. On metal bracelets, stretch between links, polished high spots on the outer surfaces and clasp wear are considered in proportion to the age of the piece. Original straps, whether rubber, leather or fabric, are checked for flexibility, colour retention and any cracking at stress points. A well-matched replacement strap does not negatively affect assessment provided the proportions and quality are appropriate.

The Role of Polishing History and Surface Finishing

Many owners wonder whether light polishing improves a Horological Machine. In most cases it does the opposite. These pieces are finished with specific brushing, bead-blasting or high-polish contrasts that are integral to their sculptural identity. Over-polishing can erase these deliberate contrasts, soften crisp edges and remove a small but meaningful amount of material from the case.

Specialists look for evidence of previous polishing by studying the transition between brushed and polished surfaces, the sharpness of any chamfers and the uniformity of the finish across flat planes. A piece that retains its original surface treatment, even with honest signs of wear, is generally preferred to one that has been refinished.

Titanium models are especially sensitive because the material does not patinate in the same way as gold. Scratches on titanium tend to remain bright rather than blending in, making the history of care immediately visible. Understanding this helps owners appreciate why the assessment values originality of finish over an artificially refreshed appearance.

Paperwork, Boxes and Supporting Materials

Original presentation boxes, outer packaging, certificates of authenticity, instruction booklets and any limited-edition cards are appreciated when they have been kept. Their condition and completeness provide additional context about how the piece has been stored over the years.

Importantly, the absence of paperwork does not prevent a valuation or sale. The physical object and its serial markings remain the definitive identifiers. Any available documents should correspond to the specific limited-edition number engraved on the case or movement.

Previous service invoices or records can be useful for understanding maintenance history but are not required. The current mechanical and aesthetic state of the Horological Machine takes precedence during assessment. Clear photographs of the piece itself, rather than reliance on documents, form the basis of the initial offer.

Recommended Storage and Care Practices

Proper storage begins with a stable environment. Maintain the Horological Machine at a steady room temperature and moderate relative humidity, away from extremes of heat or damp. Avoid locations near radiators, windows that receive direct sunlight or areas prone to sudden temperature swings that could affect the lubricants within the complex movement.

When not being worn, keep the piece in a dedicated watch box lined with soft, non-abrasive material. The box should hold the watch securely without pressing on the crystal or any protruding elements. For models with prominent rotors or spherical components, ensure nothing can make contact with these delicate parts during storage or transport.

If the watch will remain unworn for extended periods, it is safer to let it rest than to assume a watch winder is appropriate. These horological machines use complex and sometimes hand-wound movements, so unnecessary winding or constant rotation is best avoided until a specialist has inspected the piece.

Routine care consists of gentle dusting with a lint-free microfibre cloth. Never use solvents, ultrasonic cleaners or abrasive polishes. Avoid contact with perfumes, creams or household chemicals that could damage surface finishes or rubber straps. When travelling, use a robust travel case that cushions the watch against impact and vibration. These simple habits preserve both the mechanical integrity and the visual character of the piece without the need for professional intervention before selling.

Why It Is Best Not to Polish or Service Before Selling

Professional polishing or servicing immediately prior to sale can unintentionally alter the character of a Horological Machine. Polishing removes microscopic layers of metal, which over time can change the intended proportions of the case and soften the crisp lines that distinguish one generation from another. What an owner may see as restoration is often viewed by specialists as a loss of originality.

Recent service records can sometimes prompt additional questions about the quality and extent of work performed. It is far more transparent to allow the receiving team to inspect the piece in its current state, identify any genuine requirements and factor those into the final assessment. This approach respects the history of the individual object rather than presenting an altered version.

MB&F movements are highly complex, sometimes incorporating multiple balances, unusual gear trains and innovative winding systems. Unnecessary disassembly before sale risks introducing dust or minor alignment issues that were not present originally. Sending the watch exactly as it has been kept and used gives the clearest and most honest picture, leading to a more accurate and confident valuation.

The guiding principle is preservation of authenticity. Honest signs of use are understood and accepted; artificial refreshing is not. This philosophy ensures that both parties engage with the piece on genuine terms.
