A lifetime car aficionado, MB&F founder Maximilian Büsser first channelled the visual cues of the mid 20th century in the 2014 HM6 Space Pirate, particularly in its “Streamliner” SV editions. Now in 2018, MB&F goes even further and presents one of its most ambitious designs yet.

Presenting Horological Machine N°9 ‘Flow’, inspired by the dynamic profiles of automotive and aviation mid-century design.

Horological Machine N°9 ‘Flow’ is audacious in its design, not simply because of its unconventional form, but because of the extremes to which it takes this form. Mould-breaking, transgressive case shapes are nothing new to the MB&F Horological Machine collection, but HM9 has rejected all limits. Its extreme curves and acute angles required new manufacturing standards and techniques to obtain a complete milled and finished case.

Reminiscent of a jet engine, a highly complex titanium case in alternating polished and satin finishes encloses an equally complex manual winding movement, developed fully in house. Independent twin balance wheels beat at a leisurely 2.5Hz (18,000bph) on each flank of Horological Machine N°9, visible under elongated domes of sapphire crystal. A third pane of sapphire crystal on the central body reveals the gearbox of the HM9 engine: a planetary differential that averages the output of both balance wheels to provide one stable reading of the time.

HM9 Flow treads the path first opened by the HM4 Thunderbolt and subsequently by the HM6 Space Pirate, utilising a geometrically complex combination of milled sapphire crystal and 18k 5N+ red gold case elements. However, HM9 goes beyond its predecessors, redefining what was thought to be possible in case design.

Two launch editions of Horological Machine N°9 ‘Flow’ in 18k 5N+ red gold**, limited to 33 pieces each:**- Road edition with rose gold movement and speedometer-type dial;- Air edition with darkened NAC movement and aviation-style dial.
