90.RL.AB : MB&F Horological Machine N°9 HM9 Flow Air Edition Red Gold


Inspired by the dynamic profiles of automotive and aviation mid-century design, HM9 Flow treads the path first opened by the HM4 Thunderbolt and HM6 Space Pirate, utilizing a geometrically complex combination of milled sapphire crystal and titanium case elements. But HM9 goes beyond its predecessors, redefining what was thought to be possible in case design.

Reminiscent of a jet engine, the highly complex case encloses an equally complex manual winding movement, developed fully in house. Twin balance wheels beat independently on each flank of the Machine, while the central body reveals the gearbox of the HM9 engine: a planetary differential that averages the output of both balances to provide one stable reading of the time.
