An outer hull of sapphire crystal and precious metal, curved and bubbled and precisely fitted together in three parts, is sealed with a proprietary combination of patented three-dimensional gasket and high-tech compound bonding process. Two fully independent cantilevered balances channel data into a differential that turns two heartbeats into one coherent time-pulse. Ultra-precise conical gears efficiently turn the engine’s energy and information current through a 90° angle to feed the time display on a sapphire crystal dial, marked with Super-LumiNova.
On the reverse, co-axial beneath each of the balances are propellers: twin turbines that spin freely as an element of pure visual interest, waiting for someone to begin a new type of exploration. After the initial HM9 Flow ‘Air’ and ‘Road’ editions conquered land and sky, HM9-SV takes us to the depths of the ocean – the last realm on Earth that still holds a wealth of untold secrets. Before you is an exploratory vessel from Atlantis, powered by a divergent technology both familiar and strange to our eyes.
After decades confirming to the rules of corporate watchmaking, Max Büsser broke the chains and started a rebellion in 2005; a rebellion called MB&F - Maximilian Büsser & Friends.
MB&F is an artistic concept laboratory based around a simple idea: to assemble collectives of independent watchmaking professionals to develop radical watches - Horological or Legacy Machines. By nurturing teams of talented individuals, harnessing their passion and creativity and crediting each person's essential role, MB&F uses their synergy to become much greater than the sum of its parts. Respecting tradition, but never constrained by it, MB&F reinterprets traditional, high-quality watchmaking into three-dimensional kinetic sculptures.
First presented in 2018, Horological Machine N°9 – nicknamed HM9 ‘Flow’ – was a tribute to the extraordinary automotive and aeronautic designs of the 1940s and 50s. The result was a case like no other that echoed the epoch’s flowing, aerodynamic lines.
