First presented in 2018, MB&F Horological Machine N°9 – nicknamed HM9 ‘Flow’ blow our minds, but with this new Horological Machine No. 9 Sapphire Vision (HM9-SV) it’s downright astonishing. The automotive, aerodynamic shape of the HM09 is a world away from flat.
Thanks to a a transparent sapphire crystal shell and precious metal, the HM9 engine is now revealed in all its amazing details precisely fitted together in three parts, sealed with a proprietary combination of patented three-dimensional gasket and high-tech compound bonding process. Two fully independent cantilevered balances slowly beating at the frequency of 2.5 Hz (18,000 vibrations per hour), provide two sets of chronometric data that can be translated by a differential to produce one stable averaged reading. 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.
Each of the domes houses its own independent balance assembly, which meet in the middle to regulate the watch. The time is then displayed on a superluminova-marked sapphire crystal dial, all fed by a single barrel. Comprised of 301 components and 52 jewels, the HM9 engine is equipped with a single barrel delivering an autonomy of 45 hours when fully wound.
The HM9 ‘Sapphire Vision‘ comes in four editions, all with the same sapphire case: each limited to only five pieces: two editions with 18K white gold frame, featuring a PVD-coated purple or red gold-plated engine, and two editions with 18K 5N+ red gold frame, combined with a PVD-coated blue or NAC-coated black engine.
The retail price for each of the MB&F Horological Machine N°9 ‘Sapphire Vision’ editions is CHF 390,000/ Euro 362,000/ US$ 440,000. mbandf.com
