Catalogue Note

With a MB&F warranty booklet, instruction manual and presentation box.

MB&F stands for Maximillian Büsser & Friends, representing the ideal to gather the talents of various artists and watchmakers, the brand sets out on its mission to create unconventional and original horological masterpieces. Launched in 2010, Horological Machine No 4 Thunderbolt (HM4) was regarded as one of the most visually spectacular and ingenious wristwatches the watch world has ever seen. With its futuristic appearance, one would imagine the HM4 was created straight out of a science fiction but in reality, it was inspired by paintings of WWII aircrafts. The aerodynamic case and turbine-like pods bear much resemblance to the sleek form and engines of a military plane. Fitted with a three-dimensional horological engine which consists of 311 parts and a horizontal twin mainspring barrel, it took the brand 3 years to develop this technical marvel. In spite of the complex nature of the movement, the functionality of the HM4 is rather practical with separated indication of time and power reserve in individual dials. Available in only 18 pieces in pink gold and titanium, HM4 Thunderbolt serves a testament to MB&F's tireless drive to break down barriers and uncover the realm of limitless possibilities. This is the first time for HM4 in pink gold and titanium to appear in auction.
