HM4 TUNDERBOLT Titanium

A traditional wristwatch has a relatively straightforward role: to tell the time. All that is needed is a hand for the hours, another for the minutes and perhaps a power reserve indicator to keep track of running time. Horological Machine No 4 has a hand for the hours, another for the minutes and a power reserve indicator.

HM4 tells the time. HM4 is not a traditional wristwatch.

The HM4 engine is the culmination of three long years of development. Each of the 300-plus components – including the regulator and even the screws – was developed specifically for this anarchistic calibre. Horizontally configured dual mainspring barrels drive two vertical gear trains, transferring power to the twin pods indicating hours/minutes and power reserve.

Description

The sleek aerodynamic form of Horological Machine No 4’s envelope has its roots in Maximilian Büsser's childhood passion for assembling model plane kits, though none looked remotely as futuristic as these. The striking transparent sapphire section of the case requires over 185 hours of machining and polishing to transform an opaque solid block of crystal into a complex, exquisitely curved panel allowing the light to come in and the beauty of the HM4 engine to stand out. Every component and form has a technical purpose; nothing is superfluous and every line and curve is in poetic harmony. Articulated lugs ensure supreme comfort. Highly legible time is a fringe benefit.

HM4 TUNDERBOLT Titanium

The Creator

Maximilian Büsser and Friends

After decades of conforming to the rules of corporate watchmaking, Max Büsser broke the chains and started a rebellion in 2005; a rebellion called MB&F - Maximilian Büsser & Friends.

MB&F is an artistic concept laboratory based around a simple idea: to assemble collectives of independent watchmaking professionals to develop radical watches - Horological or Legacy Machines. By nurturing teams of talented individuals, harnessing their passion and creativity and crediting each person's essential role, MB&F uses their synergy to become much greater than the sum of its parts. Respecting tradition, but never constrained by it, MB&F reinterprets traditional, high-quality watchmaking into three-dimensional kinetic sculptures.

While MB&F’s futuristic Horological Machines have a firm foundation in the very best of traditional horology, Büsser wanted to pay homage to that rich tradition by imagining the type of timepieces he might create if he had been born 100 years earlier, i.e. 1867 instead of 1967. This gave birth to the more classic Legacy Machine collection.
