The brand's first creation, Horological Machine 1 (HM1) speaks of MB&F's endeavour towards cutting-edge innovations. The striking shape and size of the case design tells of MB&F's forward-looking approach, with the hour and minute dials separated by a flying tourbillon in the centre. In order for the two dials to communicate, a masterly made ultra-flat and mirror-polished wheel centrally located under the dial is used.  It floats between two layers of precision-adjusted jewels as it is too thin to be supported from its axis.

In addition, HM1 is the first wristwatch to feature a movement with four barrels connected in both parallel and series, and the first one to have two sources transmitting energy to the regulating system simultaneously. These four main barrels greatly improve accuracy, lessen wear and raise durability of HM1 by reducing the torque of each mainspring.

MB&F's HM1 is an avant-garde masterpiece that blends the groundbreaking aesthetics of micro-engineering and architecture with an astonishing level of artisan minutia into the three-dimensional timepiece.

Please note MB&F has generously offers a complimentary service for the successful buyer of this watch within six months after purchase, including shipping fee of the watch to the MB&F atelier in Switzerland. An one-year warranty will also be provided.
