GO WITH THE FLOW

Inspired by the aerodynamic design of mid-century sports cars and aircrafts, the mb&f hm9 ‘Flow’ with sexy titanium curves shows off twin, oversized balance wheels. Visible through sapphire portholes, they oscillate independently at

a frequency of 2.5Hz (18,000bph) and are linked by a planetary differential for a single, stable averaged reading. Perpendicular to the manual-winding movement

is the time display with an aviator-style dial for the

‘Air’ edition and a classic speedometer-style dial for the

‘Road’ edition, limited to 33 pieces each.
