Swiss watchmaker, Maximilian Büsser and friends (MB&F) have been busy creating yet another horological machine and it is ready for its close-up. The MB&F HM9 Sapphire Vision is the latest iteration of the now-iconic Horological Machine N°9 introduced in 2018. Inspired by automotive and aviation design from the ‘40s and ‘50s, it was named HM9 Flow and introduced a design unlike any other before – or after. HM9-SV the latest addition to the prestigious line, or Horological Machine N°9 Sapphire Vision, maintains the same outstanding design and throws in a full, clear case of sapphire crystal for good measure – and for watching the complications inside for hours on end. This limited-edition MB&F piece, like its predecessor, is massive in size, with a shape meant to replicate the aerodynamic, curved lines of retro autos. It is remarkable for the fact that, for the first time, it allows a clear view of its internal movement from all sides.
The sapphire hull is scratch- and shatter-resistant and has a metal framework that is fused to the clear case. A patented 3D rubber gasket joins the case around the movement and the three sapphire pieces are fused to the metal frame using a vacuum and high-temperature process then sealed with a special bonding compound. The result is a 52-component case, water-resistant to 3 ATM (100 ft). MB&F offers four models of the HM9-SV: two with an 18K red gold frame with either a black engine or a blue engine, and two with an 18K white gold frame with either a purple or red gold plated engine. Only five examples for each MB&F model will be made.
