MB&F Horological Machine No 4 Thunderbolt
The Thunderbolt’s 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. The sleek aerodynamic form of the Thunderbolt’s titanium and sapphire envelope has its roots in Maximilian Büsser’s childhood passion for assembling model plane kits. 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.
