MB&F

HM9 Sapphire Vision

First presented in 2018, Horological Machine N°9 – nicknamed HM9 ‘Flow’ – was inspired by the dynamic profiles of automotive and aviation design from the 1940s and 50s. The result was a case like no other that echoed the epoch’s flowing, aerodynamic lines

Despite its striking external appearance, the HM9 movement inside was described as the most beautiful movement MB&F had created to date. What other logical step was there to take, if not to encase the engine in a transparent sapphire crystal shell?

Horological Machine N°9 ‘Sapphire Vision’ or "HM9-SV" comes in four editions each limited to only five pieces: two editions with 18K 5N+ red gold frame, combined with a NAC-coated black or PVD-coated blue engine, and two editions with 18K white gold frame, featuring a PVD-coated purple or red gold-plated engine.

Worldwide shipping is offered free of charge. Local customs duties and other taxes applicable in the country of delivery are borne by the buyer.

Description


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. Two years 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.

The Creator

Maximilian Büsser and Friends

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 independant 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.
