MB&F, short for Maximilian Büsser & Friends, is one of the most unconventional names in contemporary independent watchmaking. Rather than following the traditional approach of producing watches with familiar case shapes and standard dial layouts, the brand creates mechanical objects that challenge the boundaries between horology, engineering and sculpture.
Among its most recognisable creations is the Horological Machines collection, commonly known as HM. These watches are designed to look and function like miniature mechanical sculptures worn on the wrist. Inspired by subjects such as aviation, space exploration, automobiles, architecture and the natural world, the collection demonstrates how traditional watchmaking can be reinterpreted through an imaginative design language.
The Creative Philosophy Behind Horological Machines
The Horological Machines collection reflects the founding philosophy of MB&F: to bring together talented individuals from different disciplines and create mechanical objects that would be difficult to produce within a conventional watchmaking structure.
The brand's founder, Maximilian Büsser, established MB&F as a creative platform rather than a traditional watch manufacturer. Each Machine is developed through collaboration between designers, engineers, watchmakers and specialist partners. This approach allows the team to explore ideas that may initially appear impractical or unconventional.
The result is a collection that does not follow a single visual formula. Some models resemble futuristic vehicles, while others draw inspiration from architectural structures or science-fiction imagery. Despite their different appearances, they share an emphasis on three-dimensional construction and visible mechanical engineering.
Three-Dimensional Cases and Unconventional Time Displays
One of the defining characteristics of Horological Machines is their sculptural case design. Instead of using a conventional round case with a flat dial, many HM models feature unusual shapes, raised components and multi-level constructions.
The way time is displayed is also different from that of a traditional wristwatch. Depending on the model, the hours and minutes may be shown through inclined indicators, rotating discs, domed displays or separate mechanical modules.
For example, the HM10 Bulldog features distinctive domed time displays and a mechanical jaw that opens and closes to indicate the movement's power reserve. The design transforms a practical mechanical indication into an expressive visual feature.
Other creations explore different forms of display and movement architecture. The HM11 Architect, for instance, takes inspiration from architectural concepts and presents time through an unconventional arrangement integrated into its distinctive case structure.
Mechanical Engineering as a Design Feature
In many conventional luxury watches, the movement is hidden behind the dial, with only the hands and markers visible to the wearer. Horological Machines take a different approach by making the movement an important part of the overall design.
The mechanical components are often positioned to create depth and visual movement. Bridges, gears, balance systems and other elements may be visible from multiple angles, allowing the wearer to appreciate the construction beyond the usual view through a caseback.
This approach requires careful engineering. An unusual case shape must still protect the movement, provide suitable support for the components and allow the watch to operate reliably. The display system also needs to remain readable despite the unconventional layout.
The combination of mechanical function and sculptural design is what makes the HM collection particularly distinctive within independent haute horlogerie.
A Collection Inspired by Different Worlds
Rather than developing a single design language, MB&F uses each Horological Machine as an opportunity to explore a new concept.
Aviation-inspired models often feature aerodynamic lines and cockpit-like details. Automotive references may incorporate mechanical elements reminiscent of engines or vehicle bodies. Space-themed creations use futuristic shapes and unusual displays to evoke the appearance of instruments from another world.
The HM collection also includes designs inspired by animals and architecture. These references are not simply decorative themes added to an existing watch. They influence the shape of the case, the arrangement of the movement and the way the time is displayed.
This creative freedom means that two Horological Machines can look completely different while still belonging to the same collection.
Materials and Finishing
MB&F uses a variety of materials to support the distinctive character of its Machines. Depending on the model, cases may incorporate titanium, stainless steel, gold, sapphire crystal and other specialised materials.
Sapphire crystal is particularly important in certain designs because it allows the wearer to observe the movement from unusual angles. Some models use transparent or highly sculpted crystal components that form an integral part of the visual construction.
Finishing is equally important. Polished surfaces, brushed sections, carefully shaped bridges and detailed mechanical components all contribute to the final appearance. Since many parts remain visible, the quality of their finishing becomes part of the watch's identity.
Why Horological Machines Appeal to Collectors
The appeal of the HM collection extends beyond conventional luxury-watch ownership. These creations are aimed at enthusiasts who appreciate originality, mechanical experimentation and artistic design.
Collectors may be drawn to a particular Machine because of its inspiration, movement architecture or unusual time display. Others value the collaborative nature of MB&F, where each creation represents the combined expertise of specialists from different fields.
The collection also offers considerable variety. Rather than choosing between a dress watch and a sports watch, collectors can explore mechanical objects that occupy a category of their own.
Caring for an MB&F Horological Machine
The unusual construction of Horological Machines makes proper maintenance especially important. Depending on the model, the movement may contain specialised display systems, complex gear arrangements and components that are not found in conventional watches.
Owners should avoid strong impacts and follow the handling instructions provided for their specific model. Watches with exposed or specially shaped sapphire components should be protected from accidental knocks, as damage to these parts may require specialist attention.
It is also advisable to keep the watch away from strong magnetic fields and extreme environmental conditions. If the time display becomes irregular, the power reserve changes unexpectedly or the movement stops, a professional inspection should be arranged.
Servicing should be carried out by technicians familiar with the watch's specific construction. A standard maintenance procedure may not be suitable for every MB&F Machine, particularly when the model uses an unusual display or specialised mechanical module.
Conclusion
MB&F Horological Machines demonstrate how far mechanical watchmaking can go when traditional rules are challenged. Through sculptural cases, unconventional time displays and imaginative movement architecture, the collection transforms the wristwatch into a miniature work of mechanical art.
For collectors who value creativity as much as technical craftsmanship, the HM collection offers an extraordinary perspective on modern independent watchmaking. Each Machine tells a different story, making the collection one of the most distinctive expressions of MB&F's creative philosophy.
