Maximilian Busser from MB&F:
"So here we are… the HM4 Thunderbolt Engine !
I think people will start finally understanding why we call our movements “engines”.
I wanted to present the Engine alone so that all attention can be given to this amazing piece of machinery/horology. The whole idea of MB&F being about creating “kinetic art which gives time”, this HM4 engine symbolizes pretty well our creative philosophy."
