Discover the Kerbedanz Maximus GR8 2-Minute Tourbillon – the world’s largest central flying tourbillon, redefining avant-garde Swiss watchmaking.
A Bold Evolution in Haute Horology

The Kerbedanz Maximus GR8 2-Minute Tourbillon isn’t just a watch—it’s a revolution. Recognized as the largest central flying tourbillon ever placed in a wristwatch, this masterpiece redefines the boundaries of contemporary watchmaking. Limited to only 33 pieces worldwide, it fuses monumental design with cutting-edge micromechanics, offering collectors not just a timepiece but a living sculpture of speed, precision, and elegance.
Unlike its predecessor—the monumental Maximus 6-Minute Tourbillon—the GR8 is faster, more futuristic, and uncompromisingly avant-garde, embodying the spirit of innovation that defines Kerbedanz.

Why the Maximus GR8 Matters
At first glance, the tourbillon dominates the dial with its 27mm titanium cage, three times larger than conventional designs. But scale is not excess here—it’s performance.
The 2-minute rotation speed, achieved by multiplying the pace of its tourbillon, results in a spectacle of engineering precision. Each oscillation unfolds in plain view, turning the very act of timekeeping into an immersive mechanical ballet.

Engineering the Impossible
Creating the Maximus GR8 required reimagining every component from scratch. The KRB08-2 manual-winding movement, with 381 components and 73 dedicated to the tourbillon cage, is a technological tour de force.

- Tourbillon Cage: Grade 5 titanium, 27mm diameter, weighing just 1.35 grams.
- Power System: 4 coplanar barrels operating in parallel for high torque and 54+ hours of reserve.
- Escapement: Swiss straight-line lever escapement, reducing energy loss and improving precision.
- Balance Wheel: High-inertia design at 400 g/cm², closer to a clock than a wristwatch, ensuring chronometric stability.
- Frequency: 18,000 vibrations/hour (2.5Hz).
Every component is meticulously finished: polished chamfers, sun-brushed bridges, satin steelwork, and mirror-polished screws. This is watchmaking art elevated to a monumental scale.
The Architecture of Grandeur
The case architecture is as daring as the mechanics within.
- Dimensions: 57mm x 46mm.
- Material: Grade 5 titanium or 18K gold.
- Crystal: A spherical sapphire dome, double-coated with anti-reflective treatment, allowing full immersion into the tourbillon’s kinetic dance.
- Back Design: Transparent sapphire crystal showcasing the winding system and four-barrel torque transmission.

The winding is performed via an exclusive back-mounted system with a ratchet clutch, a patented design ensuring effortless operation despite the immense power demands.
Symbolism: The Meaning of Maximus
In Roman antiquity, “Maximus” was not a name but a title, bestowed upon the Pontifex Maximus, the supreme priest of Rome. It symbolized grandeur, legacy, and ultimate authority—values immortalized in the Circus Maximus, the largest monument of ancient Rome.
The Kerbedanz Maximus GR8 draws from this heritage but projects it forward. Where the original Maximus recalled Roman grandeur, the GR8 is unapologetically futuristic, breaking free from classical forms to create a timepiece of tomorrow.
Three Reasons Behind Its Monumental Scale
- Performance Optimization – A cage large enough to use a straight-line escapement, reducing energy loss.
- Visual Spectacle – A central, oversized tourbillon under a sapphire dome, designed for pure admiration.
- Technological Challenge – Integrating such a massive structure required unprecedented innovation in watch architecture.

Beyond Time: Redefining Luxury
Owning the Maximus GR8 is not about possession—it’s about participating in a revolution. Each of the 99 timepieces is a gateway into Kerbedanz’s uncompromising philosophy: time redefined through grandeur, meaning, and modernity.
- Strap: Ergonomic FKM rubber, integrated with Kerbedanz chevrons, available in light gray, blue, or red.

- Water Resistance: 30 meters (3 ATM).
Every detail emphasizes comfort, innovation, and exclusivity.
