Inspired by airplane’s engine shape, Switzerland’s MB&F Horological Machine No. 4 Thunderbolt is an artistic time piece as well as a master work by Maximilian Busser. Horological Machine No. 4 Thunderbolt is designed with 50-jewel titanium and sapphire and the ‘engine’ itself consists of 311 components, all of which were designed specially for this particular watch over a period of three years.


“The aviation-inspired case and engine of the Thunderbolt are one,” states the MB & F website. “Neither would, nor could, exist without the other, yet each is so transcendental as to be able to stand alone as a work of art in its own right.”

There are two mainspring barrels connecting in parallel mode to keep MB&F Horological Machine No. 4 Thunderbolt running for up to 72 hours, powering the two separate jet-turbine like dials vertical gear trains, one displays minutes and hours, and the other one to displays how much power it has left.
