Inspired by the aerodynamic principles first adopted in the 1940s and 1950s, MB&F’s HM9 Flow Watch carries on that tradition of curvilinear forms. The HM9 has the appearance of being a tiny jetpack strapped to your wrist. The three distinct parts have the rounded and swooping forms popularized by the automotive and aeronautic industries. MB&F aficionados will also recognize the influence of the HM4 Thunderbolt and the HM6 Space Pirate.
Craftsmanship is taken to the next level with the milled sapphire crystals and the titanium case elements. The case is highly complex. Twin balance wheels can be viewed in the flanking pieces of the watch. Their beat is powered by the manual winding movement. The central portion—the Machine—reveals the HM9 gearbox, which is a planetary differential. The average of the output of the two balance wheel determines the time reading.
HM9 is water resistant up to 30 meters, and uses a patented 3D gasket. It measures 57mm X 47mm X 23mm—so it will sit very prominently on anyone’s wrist. It is available in two launch editions. The Road edition features gold plated movement and speedometer style dials. The Air edition has a darkened NAC movement and aviation style dials.
