Meet MB&F HM12: The Transforming Robot Watch

If you were to ask a group of watch collectors to define haute horlogerie, they would likely talk about classic round cases, hand-polished tourbillons, and centuries of Swiss tradition. But if you were to ask Maximilian Büsser, the founder of MB&F (Maximilian Büsser & Friends), he would likely show you a mechanical spaceship, a clock shaped like an arachnid, or, in this case, a watch that literally transforms into a robot.

MB&F has spent the last two decades tearing up the watchmaking rulebook and rewriting it with a sense of childlike wonder. Their “Horological Machines” are not just timekeepers; they are kinetic sculptures designed to capture the imagination. With their latest release, the HM12, MB&F has taken this philosophy to its most literal and thrilling extreme. The HM12 is not just a watch inspired by a robot—it is a watch that physically transforms into one. Let’s dive into the details of this spectacular mechanical marvel and explore how MB&F has turned childhood nostalgia into a masterpiece of luxury horology.

The Magic of Kinetic Art: How the HM12 Transforms

At first glance, the HM12 looks like a futuristic, aerodynamic instrument resting comfortably on your wrist. It features a beautifully sculpted, curved case made of Grade 5 titanium and polished sapphire crystal. But the real magic happens when you take the watch off. With a series of highly engineered, articulated movements, the watch body unfolds, extends, and reconfigures itself into a freestanding miniature robot that can sit proudly on your desk.

The transformation process is a masterclass in micro-engineering. To achieve this kinetic feat, MB&F developed a proprietary chassis system with multiple articulated joints, sliding tracks, and secure locking mechanisms.

• The Lugs as Limbs: On the wrist, the robot’s “arms” and “legs” fold inward to form the watch’s lugs, holding the custom-tapered strap securely in place. When detached, these limbs pivot outward on tiny ball joints, extending to reveal articulated hands and feet.
• The Torso and Head: The central watch dial, which acts as the robot’s torso, elevates on a vertical scissor-link mechanism. This movement reveals a hidden head segment featuring glowing, super-luminova “eyes” that peer out at the observer.
• Precision Tolerances: Because the watch must function flawlessly in both states, the tolerances for these moving parts are measured in microns. Every hinge must be tight enough to prevent rattling when worn on the wrist, yet smooth enough to transform without putting stress on the delicate mechanical movement inside.

By utilizing Grade 5 titanium, MB&F ensured that the HM12 remains incredibly lightweight on the wrist while possessing the structural integrity required for repeated transformations. It is a tactile, interactive experience that reminds us that high-end watchmaking can—and should—be incredibly fun.

A Mechanical Heart: The Movement and Display

While the transformation of the HM12 is undoubtedly the star of the show, the watchmaking craft housed within this titanium shell is equally mind-blowing. Developing a movement that can withstand the physical movement of its outer casing while keeping perfect time is no small feat. MB&F, in typical fashion, rose to the challenge by creating a fully integrated, three-dimensional engine.

The display of the HM12 is cleverly integrated into the robot’s anatomy. Rather than a traditional flat dial with ticking hands, the time is indicated via two rotating aluminum domes housed beneath a curved sapphire crystal canopy. These domes represent the robot’s “eyes” when viewed from certain angles, with one dome displaying the hours and the other displaying the minutes.

At the very center of the movement—occupying the place of the robot’s heart—beats a mesmerizing flying tourbillon. This regulating organ defies gravity and provides a constant, hypnotic pulse that brings the machine to life. The tourbillon is suspended by a elegantly curved bridge, allowing light to flood in from all angles and highlight the hand-finished chamfering, frosting, and mirror-polishing of the movement components.

The hand-wound movement boasts a generous power reserve, which is tracked by a subtle indicator located on the back of the robot’s torso. Winding the watch is an interactive ritual in itself, accomplished via a custom-designed crown shaped like a miniature winding key, paying homage to the classic tin toys of yesteryear.

The Inspiration and Legacy of Playful Horology

To truly appreciate the HM12, one must understand the philosophy of its creator. Maximilian Büsser famously likes to say, “A creative adult is a child who survived.” The HM12 is the ultimate physical manifestation of this quote. It draws heavy inspiration from the Japanese anime, Shogun Warriors, and transforming robot toys of the late 1970s and 1980s—the very toys that captured Büsser’s imagination during his childhood.

MB&F has flirted with robotic designs in the past, most notably through their table clock collaborations with Swiss clockmaker L’Epée 1839 (resulting in beloved characters like Melchior, Sherman, and Balthazar). However, shrinking this concept down to a wearable, transforming wristwatch required a completely different level of horological wizardry.

By bridging the gap between high-end Swiss craftsmanship and playful pop culture, the HM12 challenges the often stuffy and conservative world of luxury watches. It proves that a watch does not have to look like an heirloom from the 19th century to be considered a serious piece of art. It appeals to a new generation of collectors who value creativity, storytelling, and emotional connection over mere status.

Conclusion

The MB&F HM12 is much more than a device for telling time; it is a mechanical sculpture, a nostalgic time capsule, and a triumph of modern engineering. By successfully creating a high-end watch that transforms into a freestanding robot, MB&F has once again pushed the boundaries of what is possible in watchmaking.

In a world where digital smartwatches are increasingly taking over our wrists, the HM12 reminds us why mechanical watchmaking still matters. It is because of the sheer human ingenuity, the artistry, and the joy of interacting with a complex, completely analog machine. For the lucky few who will get to own this extremely limited-edition masterpiece, the HM12 offers a daily dose of wonder—and a direct link to the inner child inside us all.
