MB&F announces limited edition HM9-SV watch series
The bold Haute Horlogerie brand MB&F has become a favorite among enthusiasts in its relatively young history, due to the movement design of its movement and its continuous efforts to blur the line between watchmaking and modern sculpture. In recent years, one of the most extreme examples of the brand is the Horological Machine “Flow” No. 9 (ie HM9).
The aerodynamic “triple teardrop” form of HM9 is designed to evoke the smooth Streamline Moderne form of the 1930s and 1940s, and also contains the most exquisite movement of the brand so far claimed by MB&F founder Maximilian Büsser.
To celebrate this complex design work, MB&F returns to HM9 with a new interpretation, aiming to put the focus directly on this movement. The new limited edition MB&F Watch Machinery No. 9 “Sapphire Vision”, namely MB&F HM9-SV, reshapes one of the brand’s most fashionable appearances with a dazzlingly complex sapphire case.
The 57mm x 47mm x 23mm case of the limited edition MB&F HM9-SV may be one of the most ambitious sapphire cases ever, with a total of five anti-reflective sapphires, each with a unique shape. The largest fragment, the two covering the top and bottom of the main body shell, is an extremely complex form, with three different drop-shaped domes in addition to its unusual profile. A connected cylindrical part mates this main case with a side-mounted dial, which has both top crystal and sapphire crystal dial surfaces.
The brand claims that processing and polishing a set of crystals for each HM9-SV requires 350 hours of manual work, excluding installation to the entire structure itself. Combining all these parts together is a skeleton frame of 18K white gold or red gold, which allows the inner movement to be seen almost uninterruptedly, but adds a bit of sculptural feeling to the design. After switching to the basically sapphire-colored case, the image looks like the original HM9, with a slight change in the proportions of the case. Its spherical shape and organic impression are slightly more prominent than its predecessor.
The dial of the MB&F HM9-SV is located at the 6 o’clock position of the case, using an example inspired by the original HM9 Flow Air. The dial surface itself is equipped with a sapphire crystal, with eye-catching printed Arabic numerals and hollow Roman sword needles to ensure unobstructed views of the gear train below.
MB&F provides internal HM9 manual winding movement inside HM9-SV. There are four different surface treatments. The dial and bridge of the red gold case style are NAC coated black or PVD coated blue, while the platinum style accepts Purple PVD coating or 18K rose gold plating. The increase in colors, especially the vibrant jewel shades of blue and purple variants, greatly increases the otherworldly effect of the design.
Interestingly, although the HM9 movement is equipped with a pair of balance wheels, each pontoon on the side of the main cylinder is equipped with a balance wheel. MB&F replica deliberately avoids resonance. The movement uses a planetary differential system to balance and combine the paired speeds. More complicated is a single barrel, which divides the power between the two balances, then recombines the output and sends it to the hand. This also makes it impossible for the HM9 movement to be adjusted in a standard way, because two balances will produce two different oscillations, but the brand has developed a proprietary technology specifically for adjusting the movement. The performance of this complex power unit is a 45-hour power reserve and a beat rate of 18,000 bph.
To make the HM9-SV more spectacular, MB&F matched each color scheme with a sharp hand-stitched alligator leather strap. Both platinum case models are equipped with a deep warm mahogany brown strap, while the PVD blue movement is matched with the navy blue case. The PVD black movement version, perhaps the most conservative version in the series, is paired with a clean and simple black.
Combining one of the brand’s most eye-catching movements with one of the most ambitious and labor-intensive cases carried by the watch, there is no doubt that the limited edition MB&F HM9-SV has a pure mechanical beauty. Only five examples of each color will be produced.
