At the end of 2018, MB&F launched one of their most aggressive watchmaking machines, the HM9 "Flow".
In 2021, this Geneva-based brand further launched the new HM9 "Sapphire Vision". Thanks to the transparent sapphire crystal shell, the HM9 engine is now shown in all its amazing details.
HM9'Sapphire Vision' is inspired by the design route of cars and aviation in the middle of the last century, and is reminiscent of jet engines in a way. There are four versions, each limited to five pieces: two versions with 18K white gold mirrors Frame with PVD-coated purple or red gold-plated engine, and two versions of 18K 5N + red gold frame, and PVD-coated blue or NAC-coated black engine.
The watch case is characterized by the outer hull of sapphire crystal and precious metal, which is bent and blistered, and is divided into three parts precisely, and sealed by a proprietary combination of patented three-dimensional gaskets and high-tech composite bonding process. Ensure that the water resistance reaches 3 ATMs (approximately 30 meters / 100 feet).
